All Rights Reserved. 3 / 79 Main Circuit Wiring Method of the Three-Phase Converter (If the input is single-phase, only connect to any two phases (R+S, R+T, or S+T) Wiring Precautions: 1) Input Power Terminals R, S, T: ● No phase sequence is required for wiring the converter’s input terminaIs. ● Specifications and instaIIation methods of externaI power cabIes must compIy with IocaI reguIations and reIevant lEC standards. ● SeIect copper conductors according to the recommended vaIues in TabIe 8.3 of the manuaI. 4 / 79 2) DC Bus Terminals (+), ( -): ● Warning: After power-off, residual voltage may remain at the DC bus terminals (+), ( - ). Do not perform wiring until the CHARGE indicator is off and at least 10 minutes have passed, or there is a risk of electric shock. ● For models above 37kW (18.5kW for 220V), when using external braking units, make sure the polarity of (+), ( - ) is not reversed; incorrect wiring may cause converter damage or fire. ● The wiring length for braking units must not exceed 10 meters. Use twisted pair or closely parallel wiring. ● Do not connect the braking resistor directly to the DC bus, as this may cause serious damage or fire. 3) Braking Resistor Terminals (+), PB: ● These terminals are only valid for models 3 0kW and below (15kW and below for 220V) with built-in braking units. ● Select the braking resistor according to th e recommended values, and keep the wiring length less than 5 meters. Otherwise, it may cause damage to the converter. 4) External Reactor Terminals P, (+): For converters rated 75kW and above (37kW and above for 220V), an external reactor must be installed. When installing, remove the connection bar between terminals P and (+), and connect the reactor between these two terminals. 5) Converter Output Terminals U, V, W: ● Specifications and installation methods of external power cables must comply with local regulations and relevant IEC standards. ● Select copper conductors according to the recommended values in Table 8.3 of the manual. ● Do not connect capacitors or surge absorbers to the converter’s output side, as this may cause frequent protection trips or damage. ● For long motor cables, distributed capacitance may cause electrical resonance, damaging motor insulation or causing leakage current and converter overcurrent trips. If the motor cable exceeds 100 meters, install an AC output reactor near the converter. 6) Ground Terminal PE: ● The PE terminal must be reliably grounded. Ground resistance must be less than 0.1Ω, or it may cause malfunction or damage. ● Do not share the PE terminal with the power supply neutral (N). ● The protective ground conductor must be capable of withstanding the maximum possible short-circuit current in case of a fault. ● Select the grounding conductor size according to the table below. The cross - sectional area of a phase wire (S) The minimum cross - sectional area of the protective wire (Sp) S ≤ 16mm 2 S 16mm 2 ＜ S ≤ 35mm 2 16mm 2 35mm 2 ＜ S S/2 The protective grounding conductor must use yellow-green cables. 7) Requirements for Upstream Protective Devices: Appropriate protective devices must be installed on the input distribution circuit, providing overcurrent protection, short- 5 / 79 circuit protection, and isolation functions. When selecting protective devices, factors such as power cable current capacity, system overload capability, and short-circuit capacity of the upstream distribution must be considered. 2. Operation Display and Application Examples 2.1 Introduction to Operation and Display Interface Using the operation panel, you can modify function parameters, monitor the converter’s operating status, and control its operation (start, stop, etc.). The appearance and functional areas are shown in the figure below: Operation Panel Diagram 2.2 Function Indicator Lights Description: RUN: When lit, indicates the converter is running; when off, indicates the converter is stopped. LOCAL/REMOTE: Indicates operation mode — keypad operation, terminal operation, or remote operation (communication control). 6 / 79 LOCAL/REMOT ： Off Keypad operation LOCAL/REMOT ： On(steady) Terminal operation LOCAL/REMOT ： Blinking Remote operation FWD/REV: Forward/Reverse rotation indicator. When lit, it indicates the converter is running in reverse rotation. TUNE/TC: Tuning / Torque Control / Fault indicator Steady on: Torque control mode active Slow flashing: Tuning in progress Fast flashing: Fault condition detected Keypad Function Table Key Name Function PRG Key Enter or exit the first-level menu. Enter Key Enter the menu screens step by step and confirm the set parameters. Increment Key Increment the data or function code. Down Key Decrement the data or function code. Shift Key Under the stop display interface and the running display interface, the display parameters can be cyclically selected; when modifying parameters, the modification digit of the parameters can be selected. RUN In the keyboard operation mode, it is used for running operations. Stop / Reset Key When in the running state, p ressing this key can be used to stop the running operation; when in the fault alarm state, it can be used for reset operation. The characteristics of this key are restricted by the function code P7-02. Multifunction Select Key According to the function switching selection of P7-01, it can be defined as the command source or rapid direction switching. Potentiometer Knob According to the value in P0-03, when the value is 4, it means the frequency is controlled by the panel potentiometer (default). 2.3 Parameter Settings To achieve correct application programming, several related parameters usually need to be set. The parameter configurations are stored inside the converter and can be accessed and modified through the following operations: (1) After powering on, enter the main screen and press MODE to access the P0 parameter group. (2) Use the ▲ or ▼ buttons to browse parameter groups, and press ENTER to enter a selected group. Inside the group, continue using ▲ or ▼ to select the parameter to modify, then press ENTER to enter edit mode. 7 / 79 (3) While in parameter edit mode, use ▲ or ▼ to change the parameter value, and press to switch the digit position. (4) After modifying the value, press ENTER to save. (5) Press MODE to exit edit mode or return to the previous menu. Example: Changing function code P3-02 setting from 10.00 Hz to 15.00 Hz. If the parameter value does not have a flashing digit, it means that the function code cannot be modified. Possible reasons include: 1) The function code is a non-modifiable parameter, such as converter type, actual measurement parameters, operation record parameters, etc. 2) The function code cannot be modified while the converter is running and requires the converter to be stopped before modification. 3. Start/Stop Control of the Converter Selection of Start/Stop Signal Source The start/stop control commands of the converter come from three sources: panel control, terminal control, and communication control. The source is selected via function parameter P0-02. P0-02 Command Source Selection Factory Default: 0 Description Setting Range 0 Operation panel command channel (LED off) - Start/stop Using RUN and STOP buttons 1 Terminal command channel (LED on) DI terminal configured as start/stop command input 2 Communication command channel (LED blinking) MODBUS-RTU protocol 3.1 Panel Start/Stop Control When function code P0-02 = 0, the converter operates in panel control mode. Pressing the RUN key on the keypad starts the converter (the RUN indicator lights up). While the converter is running, pressing the STOP key stops the converter (the RUN indicator turns off).

Press MODE twice to return to the main screen. (4) Press RUN on the control panel to start the converter. Press STOP on the control panel to stop the converter. 3.2 Terminal Start/Stop Control The terminal start/stop control mode is suitable for applications where toggle switches or electromagnetic push buttons are used to start and stop the system. It is also ideal for electrical designs where the converter is controlled by a controller using dry contact signals. The control terminal layout is shown in the diagram below: Description of Control Terminal Functions Category Terminal Symbol Terminal Name Function Description Power Supply +10V-GND External +10V Power Supply It provides an external +10V power supply with a maximum output current of 10mA. It is generally used as the working power supply for an external potentiometer. The resistance range of the potentiometer is: 1kΩ~5kΩ +24V-COM External +24V Power Supply It provides an external +24V power supply, which is generally used as the working power supply for digital input and output terminals and the power supply for external sensors. The maximum output current is 200mA. OP External Power Input Terminal It is connected to +24V by default at the factory. When using an external signal to drive DI1~DI5, OP needs to be connected to an external power supply and disconnected from the +24V power supply terminal. Analog Input AI1-GND Analog Input Terminal 1 1.Input voltage range: DC 0V - 10V 2.Input impedance: 22kΩ AI2-GND Analog Input Terminal 2 1.Input range: DC 0-10V/0-20mA, which is determined by the selection of the J8 jumper on the control board. [Note: When facing th e control board, when the J8 jumper is on the right side, it is in the voltage input mode (default setting at the factory); when the J8 jumper is on the left side, it is in the current input mode.] 2.Input impedance: 22kΩ in the voltage input mode and 500Ω in the current input mode. Digital Input DI1- OP Digital Input 1 1.Optocoupler isolation, compatible with bipolar input. 2. Input impedance: 2.4kΩ 3.Voltage range for level i nput: 9V~30V. DI2- OP Digital Input 2 DI3- OP Digital Input 3 DI4- OP Digital Input 4 DI5- OP High - Speed Pulse Input Terminal In addition to the characteristics of D I1~DI4, it can also be used as a high-speed pulse input channel. 9 / 79 The maximum input frequen cy: 100kHz. Analog Output AO1-GND Analog Output 1 It is determined by the J5 jumper on the control board to select the voltage or current output. The output voltage range is 0V - 10V, and the output current range is 0mA - 20mA. Digital Output DO1-CME Digital Output 1 Optocoupler isolation, bipolar open-collector output. Output voltage range: 0V~24V Output current range: 0mA~50mA [Note: The digital output ground CME and the digital input ground COM are internally isolated. However, CME and COM are externally short-circuited at the factory (at this time, DO1 is driven by +24V by default). When DO1 needs to be driven by an external power source, the external short circuit between CME and COM must be disconnected.] FM- COM High - Speed Pulse Output It is restricted by the function code P5 - 00 "FM Terminal Output Mode Selection". When used as a high - speed pulse output, the maximum frequency can reach 10 0kHz. When used as an open - collector output, it has the same specifications as DO1. Relay output T/A-T/B Normally Closed Terminal Contact driving capacity: 250Vac, 3A, COSØ = 0.4; 30Vdc, 1A T/A-T/C Normally Open Terminal Auxiliary interface J12 Function Expansion Card Interface 28 - core terminal, interface with optional cards (such as I/O expansion cards, PLC cards, various bus cards, etc.) J3 PG Card Interface Options available: OC (Open Collector), differential, UVW, resolver and other interfaces. J7 External Keyboard Interface externally connected keyboard Others J4 PE GGN ND Connection Selection Jumper Select whether to connect PE to GND. In case of interference, connecting PE to GND can improve anti - interference. The default setting at the factory is not connected (when facing the control board, the jumper is on the left). J13 PE-COM Connection Selection Jumper Select whether to connect PE to COM. In case of interference, connecting PE to COM can improve anti - interference. The default setting at the factory is not connected (when facing the control board, the jumper is on the left). The converter supports multiple terminal control modes. The switch signal mode is determined by function code P4-11, while the input terminals for start/stop control signals are configured using function codes P4 - 00 to P4- 09. For detailed configuration, please refer to the explanations of function codes P4-11 and P4-00 to P4- 09 in the manual. Operation Procedure: 1. After powering on, enter the main screen and press MODE to access the P0 parameter group. Then press ENTER again to enter the group. The screen will display P0-00 2.

Shorting COM and DI1 will start forward operation of the converter; shorting COM and DI2 will start reverse operation. 3.3 Communication Start/Stop Control The upper-level controller controls the converter via communication using the RS485 communication protocol. The user-programmable card also communicates with the converter through data exchange over the same protocol. By setting the control command source to communication mode (P0-02 = 2), the converter Is start and stop operations can be controlled through communication. The reIated function codes for communication settings are shown in the figure beIow: The converter’s communication port is buiIt with a MODBUS-RTU slave protocol. To establish proper communication, the upper-level controller must operate as a MODBUS-RTU master. For detailed protocol definitions, please refer to the Appendix in the manual and the documentation for the RS485 communication expansion card. 11 / 79 4. Frequency Control of the Converter 4.1 Selection of Main Frequency Reference Source The converter offers 9 types of main frequency reference sources, including: Digital setting (UP/DOWN without power-down memory) Digital setting (UP/DOWN wi th power-down memory) AI1 AI2 AI3 Pulse input Multi-step command Simple PLC PID Communication reference The desired source can be selected via function code P0-03. P0-03 Selection of the main frequency source X 0: Digital setting (Preset frequency P0 - 08, can be modified by UP/DOWN keys, not memor ized after power - off) 1: Digital setting (Preset frequency P0 - 08, can be modified by UP/DOWN keys, memorized after power - off) 2: AI1 3: AI2 4: AI3 (Panel potentiometer) 5: PULSE pulse setting (DI5) 6: Multi - step command 7: Simple PLC 8: PID 9: Communication given 4.2 Frequency Reference Demonstration From the main screen, press MODE to access the P0 parameter group.
