5.2 Wiring Connections

All wiring must be performed by a qualified electrician in accordance with local and national electrical codes. Ensure power is disconnected before making any connections.

• Input Power (220V): Connect the incoming AC power to the input terminals (R, S, T for 3-phase or L1, L2 for single-phase). This VFD supports both single-phase and three-phase 220V input.
• Motor Output: Connect the three-phase motor leads to the output terminals (U, V, W). Ensure correct phase sequence for desired motor rotation.
• Grounding: Connect the ground terminal of the VFD to a reliable earth ground. The motor frame must also be properly grounded.
• Control Terminals: Utilize the control terminals for external control signals such as start/stop commands, speed reference (e.g., potentiometer, 0-10V, 4-20mA), and fault indications. Refer to the detailed wiring diagram in the full product manual for specific terminal assignments.
• RS485 Communication: If using MODBUS communication, connect the RS485 A and B lines to the designated terminals.

Note: Always refer to the wiring diagram provided with your specific VFD unit for precise terminal identification and connection instructions.

6. Operating Instructions

6.1 Basic Operation

1. Power On: After ensuring all connections are secure and safe, apply power to the VFD. The digital display will illuminate.
2. Start Motor: Press the RUN button on the control panel to start the motor.
3. Stop Motor: Press the STOP button to stop the motor.
4. Reverse Direction: Press the REV button to change the motor's rotation direction.

6.2 Speed Control

Motor speed can be controlled via the built-in potentiometer, external analog signals (e.g., 0-10V, 4-20mA), or digital inputs, depending on parameter settings.

• Potentiometer: Rotate the potentiometer knob on the control panel to adjust the output frequency and thus the motor speed.
• External Analog Input: If configured, an external voltage or current signal connected to the AI terminals can control the speed.
• Digital Inputs: Pre-set speeds can be selected using digital input terminals, often used with the PLC function.

6.3 Parameter Settings

The VFD has numerous parameters that can be adjusted to customize its operation for specific applications. These parameters control motor characteristics, acceleration/deceleration times, control modes, and protective functions.

1. Enter Program Mode: Press the PRGM button to enter the parameter setting mode.
2. Navigate Parameters: Use the UP and DOWN arrow buttons to scroll through parameter groups and individual parameters.
3. Select Parameter: Press SET to select a parameter for editing.
4. Adjust Value: Use the UP and DOWN buttons to change the parameter value. The SHIFT button can be used to move the cursor for digit selection.
5. Save Value: Press SET again to save the new value.
