Energy Saving Principle
For traditional injection molding machines with constant delivery pumps, valve adjustment is required to change load flow rate and pressure. In this case, input power changes slightly, and a large proportion of energy is consumed by the valve in the form of pressure difference, causing overflow.
CHV110 energy saver can automatically adjust the rotation speed and oil supply quantity of the oil pump based on the current working state of an injection molding machine, like mold clamping, injection, melting, mold opening, and ejector pin, and according to the set pressure and speed requirements, so that the actual oil supply quantity of the oil pump can be consistent with the actual load flow rate of the injection molding machine at any stage. As a result, it minimizes the energy consumption when the motor operates in its load range, eliminates overflow phenomenon, and ensures stable and precise operation of the motor.
Application of CHV110 energy saver makes soft start possible for the motor of injection molding machines, improves the power factor COS∮ of the motor, and dynamically adjusts the output power of the motor of injection molding machines. In this way, the energy is saved.

∙To prevent injection molding machine signals from interference, please select a shielded cable as the signal line of the injection molding machine card.
∙The shielding layer of the shielded signal line cable of the injection molding machine card should be grounded (such as terminal PE of the inverter), and furthermore, only one end is grounded, to prevent signal interference.
4.5 Signal Acquisition Method of Injection Molding Machine
To install an energy saver correctly for an injection molding machine, it is necessary to precisely identify the proportional flow and proportional pressure signals, which serve as input signals for the energy saver. There are three methods as follows:
Method 1: Collecting signals from proportional flow and proportional pressure ammeters. Most injection molding machines have these two ammeters. They are usually installed on the panel of or in the distribution box of an injection molding machine. The range of an ammeter is usually 0-1A. To distinguish a proportional flow ammeter from a proportional pressure ammeter, set an action parameter of the injection molding machine to 0 (for flow) or 50 (for pressure) and then perform the action. The ammeter whose pointer moves is the proportional pressure ammeter. The proportional flow ammeter is alike.
Proportional Flow Ammeter Proportional Pressure Ammeter
Method 2: Collecting signals from proportional pressure and proportional flow signal amplifier board. On the signal amplifier board, the user can find power amplification transistors for pressure and flow signals. In other words, the circuit board that has two power transistors is the proportional pressure and proportional flow signal board. Moreover, the first letters of pressure and flow are marked on the wiring terminals of the circuit: pressure (P+, P-) and flow (F+, F-). The user can also determine whether it is proportional pressure or proportional flow signal by the current scale of a multimeter.
Method 3: Collecting signals on the proportional pressure and proportional flow solenoid valves. On the oil way block on the both ends of an injection molding machine, there are a number of solenoid valves, most of which are directional valves. Unlike directional valves, the proportional pressure and proportional flow solenoid valves are often combined together and looks much bigger than flow valves. The user can also determine whether they are proportional pressure and proportional flow solenoid valves by the current scale of a multimeter.
Note: Proportional pressure and flow signals must be 0-1A current signals, and the signal acquisition card must be connected in series with such signals. Proportional pressure and flow signals flow into the signal acquisition card from 1IA/2IA, and flow out from 1IB/2IB. If the signal acquisition card is reversely connected, it cannot collect any signals and the injection molding machine has no action signal.

4.7 Operation Procedures
4.7.1 Parameter setting
Three-level menus:
1)Functional code group number (level-1 menu);
2)Functional code ID (level-2 menu);
3)Functional code set value (level-3 menu).
Note: In level-3 menu operation, press For example, change the value of the functional code P1.01 from 00.00 Hz to 01.05 Hz. Stop/Run Figure 4.7.1 Level-3 Menu Operation Flow Diagram In the level-3 menu, if no bit of parameters flickers, it indicates the functional code cannot be modified. The possible causes include: 1)The functional code cannot be modified, for example, actually measured parameters and operation record parameters. 2)The functional code cannot be modified in the operation state; you have to stop the equipment before modifying the functional code. 4.7.2 Shortcut menu Shortcut menu provides a quicker and more convenient means for viewing and modifying functional parameters. The user can add frequently used functional parameters to the shortcut menu. Parameter in the shortcut menu is displayed in the format of “hp0.11”, indicating that it is the functional parameter P0.11. Modifying a parameter in the shortcut menu has the same effect as modifying the parameter in the common programming state. A maximum of 16 functional parameters can be added t the shortcut menu. The user can add or delete functional parameters to or from the shortcut menu when the functional code F7-03 is set to 0. 4.7.2-1 Adding shortcut parameter: To set the functional code P0.00 as a shortcut parameter, for example, operate as follows: Stop/Run Figure 4.7.2-1 Example of Adding Shortcut Menu Note: Press 4.7.2-2 Operation of shortcut parameters The shortcut menu contains only two levels, corresponding to the level-2 and level-3 menus in the common programming state. An operation example is as follows: Figure 4.7.2-2 Example of Shortcut Menu Operation Note: In the stop or operation display interface, press If the “NULLP” appears when the user enters the level-1 shortcut menu, it indicates the shortcut menu is null. 4.7.2-3 Deleting shortcut parameters Figure 4.7.2-3 Example of Shortcut Menu Deletion Operation Note: Press 4.7.3 Fault reset If a fault occurs with the inverter, the inverter will give a prompt on fault information. The user can perform fault reset operation through the 4.7.4 Parameter copying For details, refer to the functional description of the external LCD keypad. 4.7.5 Motor parameter self-learning The user can select the operation mode with or without PG vector control. Enter the parameters on the name plate of a motor correctly before starting the inverter. For c series inverters, the user has to match the standard motor parameters according to the parameters on their name plates. Vector control mode depends largely on motor parameters. To ensure good control performance, it is required to obtain correct parameters of the controlled motor. Operating procedures for motor parameter self-learning are as follows: Firstly, select the operation command channel selection (P0.01) as the keypad command channel. Then, enter the following parameters according to the name plate of the motor: P2.01: Rated frequency of the motor; P2.02: Rated rotation speed of the motor; P2.03: Rated voltage of the motor; P2.04: Rated current of the motor; P2.05: Rated power of the motor. Set P0.17 to 1. For detailed description of motor parameter self-learning process, refer to the description of the functional code P0.17. Press P2.06: Resistance of the motor stator; P2.07: Resistance of the motor rotor; P2.08: Inductance of the motor stator and rotor; P2.09: Mutual inductance of the motor stator and rotor; P2.10: Motor no-load current; implementing motor parameter self-learning. Note: The motor must be separated from the load; otherwise, motor parameters obtained from self learning may be incorrect. 4.8 Installation and Debugging Procedures 4.8.1 Connection of lines 4.8.1-1 The connection method of the power line is as follows: Correctly identify the main AC contactor for the startup of the motor, disconnect the 3-phase AC wires between the air switch of the injection molding machine and the main AC contactor (Note that if the main AC contactor has other power lines, re-connect them to the air switch), and then connect the 4.8.1-2 The connection method of the signal line is as follows: Correctly identify proportional flow signal and proportional pressure signal. When the signal is the current signal, 1IA and 1IB on the signal acquisition card are input terminals for current signal channel 1, and the corresponding internal channel is AI3. The functional code is P0.03=2, and the corresponding parameters are set to P5.25-P5.29. Where the 1IA is the positive input terminal of differential current and the 1IB is the negative input terminal of differential current. 2IA and 2IB are input terminals for current signal channel 2, and the corresponding internal channel is AI4. The functional code is P0.04=1 and the corresponding parameters are set to P5.30-P5.34. Where the 2IA is the positive input terminal of differential current and the 2IB is the negative input terminal of differential current. Besides, the combination mode of these two signal channels is set by the parameter P0.06. Please pay attention to the flow direction of current on the signal line; the user can also make a judgment according to the on/off status of the indicator (the brightness of the indicator varies with the current signal). When the current signal is greater than 0.6A, all indicators become on, indicating the wiring is correct. 4.8.1-3 Upon completion of wiring, test the direction of mains supply mode and energy saving mode, make sure the phase sequence of corresponding motors of the injection molding machine is consistent, and measure signals on two channels with a multimeter to check whether the output is normal. 4.8.2 Perform motor parameter self-learning. Self-learning steps are precautions are as follows: 4.8.2-1 Enter correctly the parameters on the name plate of the motor. The corresponding functional codes are P2.01 to P2.05. a) Enter rated power of the motor (very important) 4.8.2-4 After self-learning of motor parameters, check the parameter P2.10. The value shall be less than 60% of the rated current of the motor (P2.04); otherwise, it is abnormal, and it is necessary to confirm whether the motor is free of load when the parameter self-learning takes place. 4.8.2-5 After the self-learning, the user cannot change parameters in group P2 at will. If any parameter on the name plate of the motor (P2.01-P2.05) changes, it is necessary to conduct the motor parameter self-learning again. 4.8.2-6 If parameters on the name plate of the motor are unavailable, use default parameters. In this case, enters motor power (P2.05) only, and it is unnecessary to carry out parameter self-learning. 4.8.2-7 If the user wants to change the result just after the completion of self-learning, the user can change the rated power of the motor (P2.05) to a different value, and then change it to the current required value. A default value will be generated automatically. 4.8.3 Before debugging, conduct commissioning with the keypad to observe whether the system runs normally and whether motor parameters are correct. 4.8.3-1 Set P0.00=0 (Open loop vector control), P0.11=0.1s (acceleration time), P0.10 = 50.00 Hz. Conduct acceleration and deceleration for several times. If no OC fault occurs, the system is normal. 4.8.3-2 When the motor reaches its rated frequency (P2.01), view the output voltage with the 4.8.3-3 When the motor reaches half of its rated frequency (P2.01), view the output voltage. If the output voltage is about half of the rated voltage, it indicates the system is normal; otherwise, motor parameters are incorrect. If the output voltage is excessively high, appropriately reduce the no-load current of the motor (P2.10); if the output voltage is excessively low, appropriately increase the no-load current of the motor (P2.10). 4.8.4 Debugging contents Enter the corresponding functional code and set the parameters by referring to the following settings: 4.8.4-1 Modify the following basic parameters: 4.8.4-3 During the use of the energy saver, if protection function is incorrectly enabled, motor parameters may be incorrect. Change P0.00 to 2 (V/F control) and try to identify the cause. 4.8.4-4 Make sure the motor is in the stop state during the switchover between the mains supply mode and energy saving mode; otherwise, the inverter will generate an OC fault. 4.8.5 If multi-step speed is required for the commissioning of some injection molding machines, try the following methods: 4.8.5-1 Set the following parameters through the JOG terminal (S2): 5.1 Switchover between Mains Supply Mode and Energy Saving Mode 5.1.1 Energy saving to mains supply operation ∙The energy saver operates in the energy saving state and the energy saving operation indicator is on. ∙Shut down the main oil pump motor and make sure the motor stops. ∙Turn the changeover switch and the mains supply operation indicator becomes on. The energy saver operates in the mains supply state. ∙Turn on the main motor of the injection molding machine and perform normal operations. 5.1.2. Mains supply to energy saving operation ∙The energy saver operates in the mains supply state and the mains supply operation indicator is on. ∙Shut down the main oil pump motor and make sure the motor stops. ∙Turn the changeover switch and the energy saving operation indicator becomes on. The energy saver operates in the energy saving state. ∙Turn on the main motor of the injection molding machine and perform normal operations. Key Point With the same mold and materials, the quantity of electricity consumed by an injection molding machine in the energy saving operation sate and in the mains supply operation state can be measured respectively by the switchover between these two modes. Therefore, the energy saving ratio can be calculated. During the switchover, production technicians must be on the site to inspect product quality. In the energy saving operation state, some injection molding machines may have different technological process flow rate (speed) parameters and pressure parameters from those in the mains supply operation state. Parameters of the injection molding machines in energy saving operation mode are set to values comparatively greater than those set in mains supply operation mode. For these injection molding machines, parameters have to be adjusted when performing the switchover between mains supply mode and energy saving mode to turn out qualified products. 5.3 Normal Operation Stage of Energy Saver After the energy saver is installed and debugged, always turn it to the energy saving operation mode unless it is required to have a test. It is not necessary for a user to adjust the parameters of the energy saver when a different type of mold is used. No matter what kind of product is produced, it is only required to set the flow (speed) and pressure parameters of the injection molding machine at different stages such as mold clamping, injection, melting, mold opening, and ejector pin, until the qualified products are turned out. Note: 1)Never turn the changeover switch when the equipment is running; otherwise, the energy saver may fail. 2)Do not perform the mains supply/energy saving mode switchover frequently; otherwise, it may lead to protection action of the energy saver. Warning! Do not connect the AC power with output terminals (U, V, W); otherwise, it may cause personal injury or accident. 6.1 Fault Diagnosis and Corrective Action If a fault occurs during the operation of the inverter, the LED display automatically shows the fault. At this time, energy saver has implemented effective protection against the fault. The output terminal stops output and the fault indicator flickers.

After reset, stop the energy saver and then turn it to the energy saving state, and start the motor. Shut down the main power supply of the energy saver and power on it again after all LEDs on the keypad are off, and then start the oil pump motor. 6.2.2 No display when energy saver powered on Check whether the power supply of the energy saver is consistent with the rated voltage. If there is a fault with the power supply, check and remove the fault. Check whether the 3-phase rectifier bridge is in good condition. If it is broken, seek for external service. Check whether the CHARGE indicator is on. If it is off, the fault usually lies on the rectifier bridge or buffer resistor; if it is on, the fault may lie on the switching power supply. In this case, seek for external service. 6.2.3 Power supply air switch tripped when energy saver powered on Check whether power supplies are grounded securely or short-circuited; remove the fault if any. Check whether the rectifier bridge is broken down. If it is broken down, seek for service. 6.2.4 Motor does not rotate after the energy saver runs Check whether U, V, W terminals have balanced 3-phase output. If yes, the motor lines or the motor itself may be damaged, or the motor is blocked due to mechanical reasons. Please remove the fault. It may have output but three phases are unbalanced. It may be a fault with the drive board or output module of the energy saver. Please seek for service. If there is no output voltage, it may be a fault with the drive board or the output module. Please seek for service. 6.2.5 The display is normal when the energy saver is powered on, but power supply air switch is tripped when energy saver is running: Check whether there is short circuit between output modules. If yes, seek for external service. Check whether leads of motor are short-circuited or grounded. Remove the fault if any. If the tripping occurs occasionally and the distance between the motor and the energy saver is far, an output AC reactor may be added. Note Only qualified and service-trained personnel can conduct maintenance operation. Before carrying out maintenance operation, shut down the power of the inverter first and wait at least 10 minutes. Do not directly touch components on the PCB; otherwise, the inverter may be damaged by static electricity. Upon completion of maintenance, make sure to tighten all screws. To prevent energy saver failure, ensure normal operation of the equipment, and prolong the service life of the energy saver, it is necessary to carry out daily maintenance for the energy saver. Daily maintenance covers: To prevent energy saver failure and ensure its long-term, high-performance and stable operation, users must carry out a periodic check (within six months) for the energy saver. The check covers: 2.Replace the fan The product warranty is subject to the following provisions: 8.1 In case of quality defects, the warranty covers: 8.1-1 For domestic use ∙A warranty of repair, replacement, or return in one month from the date of shipment; ∙Repair or replacement in three months from the date of shipment; ∙Repair in 18 months from the date of shipment. 8.1-2 For overseas use ∙For overseas use (excluding domestic use), the warranty covers repair in the place of purchasing in 12 months from the date of shipment. 8.2 Even within the warranty period, this warranty does not apply to (but paid maintenance service is available for): ∙Fault or damage caused by inappropriate operation or unauthorized repair or modification; ∙Fault or damage caused by use against the requirements specified in standards and specifications; ∙Component aging or fault caused by the use in an environment incompliant with the environment requirements provided in this manual; ∙Damage arising from natural disasters such as earthquake, fire, wind storm, flood, lightning strike, abnormal voltage or other consequential damage; ∙Equipment fault or damage when the purchaser fails to pay up the payment for the equipment as agreed. 8.3 Life-long paid maintenance service is provided for our products no mater when and where you buy it. Additional Information Based on frequency conversion and speed adjusting principles, the following difference may occur when the injection molding machine operates in the energy saving mode in comparison with operating with mains supply. It is normal if such difference is kept under certain limit. ∙Sharper Noise The energy saver adopts frequency conversion technology to drive the oil-pump motor of the injection molding machine. According to characteristics of CHV110 series of energy savers, energy savers are driven by multiple pulses. Therefore, the motor gives out sharp noise of different loudness when it is running at different speeds. ∙Higher Temperature (about 5°C) The energy saver is driven by multiple pulses. Therefore, the temperature of the motor operating in the energy saving mode is slightly higher than that of the motor operating in the mains supply mode. At the low-speed operation stage, the temperature may increase by 5 to 8°C. Since the oil-pump motor of an injection molding machine usually runs at a medium or low speed in the energy saving mode, the temperature is about 5°C higher than that in the mains supply mode. The temperature-resistant grade of all materials used for the oil-pump motor is at grade F (resistant to a temperature up to 135°C) or above. Therefore, the temperature raise of the motor is within the permitted scope and will not have any impact on the use and service life of the motor. Attachment 1: List of Functional Parameters Functional parameters of the CHV110 energy saver can be functionally divided into sixteen groups (P0 through PF). Where, PF refers to extended functional parameters. After the corresponding extension card is installed on the energy saver, the user can access to the group of parameters. Each functional group contains certain functional codes. Three levels of menus are used for the functional codes. For example, “P8.08” indicates the eighth functional code of the P8 functional group. For the convenience of functional code setting, upon operation through the operation panel, the functional group numbers correspond to the level-one menu, the functional code numbers to the level-two menu, and functional code parameters to level-three menu. 1. The contents of the functional list are described as follows: “Functional Code” in the first column: number of the functional parameter group and parameter; “Name” in the second column: complete name of the functional parameter; “Detailed Parameter Description” in the third column: detailed description of the functional parameter; “Setting Range” in the fourth column: valid setting range of the functional parameter; “Default Value” in the fifth row: original default setting of the functional parameter; “Change” in the sixth row: change property of the functional parameter (that is, whether to allow change and the change conditions); The description is as follows: “O”: indicates that the setting value of the parameter can be changed upon stop and running of the energy saver; “”: indicates that the setting value of the parameter cannot be changed during running of the energy saver; “●”: indicates that the parameter value is the actually detected and recorded value and cannot be changed. (The energy saver has conducted automatic detection restriction upon the modification properties of the parameters, so that the user can avoid modifications by mistake). ) “LCD Display” in the seventh column: brief description of the functional parameter name on the LCD display in the operation panel. “Serial No.” in the eighth column: sequence number of the functional code among all the functional codes, and likewise, it also indicates the register address in communications. 2. “Parameter Notation” is decimal (DEC) notation. If hexadecimal notation is used for parameters, the data of each bit is mutually independent upon parameter editing. The range value of some bits can be in hexadecimal notation (0~F). 3. “LCD Display Description” in the table is only valid when an external LCD operation panel is used. 4. “Default Value”: indicates the value after the refreshing of the functional code parameter upon default parameter operation recovery operation. However, the actually detected parameter values or recorded values will not be refreshed. 5. To protect parameters more efficiently, the energy saver provides password protection for the functional codes. After a user password (that is, the parameter if user password P7.00 is not zero) is set, when the user press Functional Code 1: Vector control with PG 2: V/F control 1: Terminal command channel (LED flashes) 2: Communication command channel (LED lights up) 1: Enabled, and not stored upon inverter power-off 2: Invalid 1: Analog AI1 setting 2: Analog AI3 setting 3: High-speed pulse setting (HDI1) 4: Simple PLC program setting 5: Multi-step running setting 6: PID control setting 7: Remote communication setting 1: Analog AI4 setting 2: High-speed pulse setting (HDI2) 1: Frequency A command 1: B 2: A+B 3: Max(A, B) 1: Running in opposite direction 2: Reverse running prohibited 1: Parameter self-learning 1: Recover default value 2: Clear fault files 1: Stop 2: Dormant and standby 1: Full-range enabled 2: Disabled upon deceleration 1: Automatic energy-saving running 1: HDI1 is digital input, HDI2 is high-speed pulse input 2: HDI2 is digital input, HDI1 is high-speed pulse input 3: HDI1 and HDI2 are digital inputs 1: Communication virtual terminal input 1: Forward running 2: Reverse running 3: 3-wire run control 4: Forward jogging 5: Reverse jogging 6: Free stop 7: Fault reset 8: Run pause 9: External fault input 10: Frequency setting increment (UP) 11: Frequency setting decrement (DOWN) 12: Frequency increase/decrease setting clear 13: Switching between A setting and B setting 14: Switching between (A+B) setting and A setting 15: Switching between (A+B) setting and B setting 16: Multi-step speed terminal 1 17: Multi-step speed terminal 2 18: Multi-step speed terminal 3 19: Multi-step speed terminal 4 20: Multi-step pause 21: Acceleration/deceleration time selection 1 22: Acceleration/deceleration time selection 2 23: Simple PLC reset 24: Simple PLC pause 25: PID control pause 26: Wobble frequency pause (stop at the current frequency) 27: Wobble frequency reset (return to center frequency) 28: Counter reset 29: Length reset 30: Acceleration/deceleration disabled 31: Torque control disabled 32~47: Reserved 1: Two-wire control, with separated enable and direction 2: Three-wire control 1 3: Three-wire control 2 UP/DOWN Frequency increment change rate 1: Counter input 2: Length count input 3: reserved 4: reserved 1: English 1: Valid for panel and terminal control 2: Valid for panel and communication control 3: Valid for all control modes 1: Phase U protection of inverter unit (OUT1) 2: Phase V protection of inverter unit (OUT2) 3: Phase W protection of inverter unit (OUT3) 4: Acceleration overcurrent (OC1) 5: Deceleration overcurrent (OC2) 6: Constant overcurrent (OC3) 7: Acceleration overvoltage (OV1) 8: Deceleration overvoltage (OV2) 9: Constant overvoltage (OV3) 10: Bus under-voltage fault (UV) 11: Motor overload (oL1) 12: Inverter overload (oL2) 13: Input phase failure (SPI) 14: Output phase failure (SP0) 15: Overheat fault of rectifier module (OH1) 16: Overheat fault of inverter module (OH2) 17: External fault (EF) 18: Communication fault (CE) 19: Current detection fault (ITE) 20: Motor self-learning fault (TE) 21: Coder disconnection fault (PCE) 22: Coder reverse direction fault (PCE) 23: System fault (OPSE) 24: FEPROM operation fault (EEP) 25: PID feedback disconnection fault (PIDE) 26: Brake unit fault (BCE) 27: reserved 1: Action 1: protection enabled 1: protection enabled 1: Common motor (with low-speed compensation) 2: Variable frequency motor (without low-speed compensation) 1: corresponding to the rated current of the motor, tested at constant speed 2: corresponding to the rated current of the inverter, tested all the time 3: corresponding to the rated current of the inverter, tested at constant speed 1: protection enabled 1: protection enabled Brake resistor (option) Card No.: - Through strict quality control and inspected by the quality assurance department, the performance parameters of the product comply with the standard specified in the Operating Instructions delivered with the device, and the product is allowed to leave factory. 2 For overseas use (excluding domestic use), the warranty covers repair in the place of purchasing in twelve months from the date of shipment. 3.
