Err01 fault in Emotron VS Series Drive

-
Err01 fault indicates Accel overcurrent. This means the inverter's output current has exceeded the safe threshold during the motor's acceleration phase. Possible Causes: 1: The output circuit is grounded or short circuited. 2: The acceleration time is too short. 3: Manual torque boost or V/F curve is not appropriate. 4: The voltage is too low. 5: The startup operation is performed on the rotating motor. 6: A sudden load is added during acceleration. 7: The AC drive model is of too small power class. Solutions: 1: Eliminate external faults. 2: Increase the acceleration time. 3: Adjust the manual torque boost or V/F curve. 4: Adjust the voltage to normal range. 5: Select rotational speed tracking restart or start the motor after it stops. 6: Remove the added load. 7: Select an AC drive of higher power class.

Err02 fault indicates Decel overcurrent. This means the inverter's output current has exceeded the safe threshold during the motor's deceleration phase. Possible Causes: 1: The output circuit is grounded or short circuited. 2: The deceleration time is too short. 3: The voltage is too low. 4: A sudden load is added during deceleration. 5: The braking unit and braking resistor are not installed. Solutions: 1: Eliminate external faults. 2: Increase the deceleration time. 3: Adjust the voltage to normal range. 4: Remove the added load. 5: Install the braking unit and braking resistor.

Err03 fault in Emotron VS Series Drive

-
Err03 fault indicates Constant-speed overcurrent. This means the inverter's output current has exceeded the safe threshold while the motor was operating at a steady, constant speed. Possible Causes: 1: The output circuit is grounded or short circuited. 2: The voltage is too low. 3: A sudden load is added during operation. 4: The AC drive model is of too small power class. Solutions: 1: Eliminate external faults. 2: Adjust the voltage to normal range. 3: Remove the added load. 4: Select an AC drive of higher power class.

Err04 fault in Emotron VS Series Drive

-
Err04 fault indicates Accel overvoltage. This means the drive's internal DC bus voltage has risen above the maximum safe limit during motor acceleration. Possible Causes: 1: The input voltage is too high. 2: An external force drives the motor during acceleration. 3: The acceleration time is too short. 4: The braking unit and braking resistor are not installed. Solutions: 1: Adjust the voltage to normal range. 2: Cancel the external force or install a braking resistor. 3: Increase the acceleration time. 4: Install the braking unit and braking resistor.
