Before starting, ensure the power has been disconnected for at least 5 minutes to allow capacitors to discharge. R, S, T: Terminals for 3-phase AC input. U, V, W: Terminals for 3-phase AC output to the motor.
If the inverter stops, the LED display will show a fault code:
Spare terminals for external braking units or DC reactors. Invt CHE100 Inverter User Manualpdf
Typically set to 50Hz or 60Hz depending on your motor's rating.
Sensorless Vector Control (SVC) for high precision and high torque at low speeds, and standard V/F control. Output Frequency: 0Hz to 400Hz. Starting Torque: 150% of rated torque at 0.5Hz (SVC mode). Before starting, ensure the power has been disconnected
Set to 1 to restore the drive to original factory settings.
Set to 1 to perform dynamic autotuning, which optimizes the drive's interaction with your specific motor. Troubleshooting Common Fault Codes If the inverter stops, the LED display will
