Err02
Overcurrent
during
acceleration
1. The output circuit is short circuited.
2: The acceleration time is too short.
3: Manual torque boost or V/F curve is not
appropriate.
4: The power supply 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.
1: Eliminate short circuit.
2: Increase the acceleration time.
3: Adjust the manual torque boost or V/F curve.
4: Check that the power supply is normal.
5: Select speed
tracking restart or start the motor after
it stops.
6: Remove the added load.
7: Select a drive of higher power class.
Err03
Overcurrent
during
deceleration
1. The output circuit is short circuited.
2: The deceleration time is too short.
3: The power supply is too low.
4: A sudden load is added during deceleration.
5: The braking resistor is not installed.
1: Eliminate short circuit.
2: Increase the deceleration time.
3: Check the power supply, and ensure it is normal.
4: Remove the added load.
5: Install the braking resistor.
Err04
Overcurrent at
constant speed
1. The output circuit is short circuited.
2: The power supply is too low.
3: A sudden load is added during operation.
4: The AC drive model is of too small power class.
1: Eliminate short circuit.
2: Adjust power supply to normal range.
3: Remove the added load.
4: Select a drive of higher power class.
Err05
Overvoltage
during
acceleration
1: The DC bus voltage is too high
ƿ
.
2: An external force drives the motor during
acceleration.
3: The acceleration time is too short.
4: The braking resistor is not installed.
1: Change with a proper braking resistor.
2:
Cancel the external force or install braking resistor.
3: Increase the acceleration time.
4: Install the braking resistor.
Err06
Overvoltage
during
deceleration
1: The DC bus voltage is too high
ƿ
.
2: An external force drives the motor during
deceleration.
3: The deceleration time is too short.
4: The braking resistor is not installed.
1: Change with a proper braking resistor.
2: Cancel the external force or install braking resistor.
3: Increase the deceleration time.
4: Install the braking resistor
Err07
Overvoltage at
constant
frequency
1: The DC bus voltage is too high
ƿ
.
2: An external force drives the motor during
deceleration.
1: Change with a proper braking resistor.
2: Cancel the external force.
