iDrive2 inverters
1. Check to ensure keypad functions and displays correctly.
2. If OK, please check P07 and ensure the corresponding recorded fault parameters to confirm the real state when
the current fault occurs by all parameters.
3. See the following table for possible cause and remedial action.
4. Remove fault, if error still exists, consult IMO..
5. Check to eliminate the fault and carry out fault reset to run the inverter.

Fault type
1. The acceleration or
deceleration is too fast.
2. The voltage of the grid is too
low.
3. The power of the inverter is
too low.
4. The load transients are
abnormal.
5. Short circuit or phase loss.
6. There is strong external
interference.
1. The input voltage is abnormal.
2. Voltage regeneration.
speed.
The voltage of the power supply
is too low.
1. The voltage of the power
supply is too low.
2. The motor setting rated
current is incorrect.
3. The motor stalls or load
transients is too strong.
The inverter will report overload
pre-alarm according to the set
value.
Possible cause
69
Fault tracking
Remedy action
1. Increase the ACC time
2. Check the input power
3. Select the inverter with a larger
power
4. Check if the load is short
circuited (the grounding short
circuited or the wire short
circuited) or the rotation is not
smooth.
5. Check the output
configuration.
6. Check for mechanical
resistance.
1. Check the input power.
2. Extend the accel/decel time.
3. Connect external braking
resistor.
Check the input power of the
supply line.
1. Check the power of the supply
line
2. Reset the rated current of the
motor
3. Check the load and adjust the
torque lift
Check the load and the overload
pre-alarm point.
