Fault Descriptions

Over-current during
deceleration
(ocd)
Output current exceeds 2.4 times of rated current during
deceleration.
When ocd occurs, the drive closes the gate of the
output immediately, the motor runs freely, and the
display shows an ocd error.
Action and Reset
Action level
240% of rated current
Action time
Immediately act
Fault treatment parameter
N/A
Reset method
Manual reset
Reset condition
Reset in 5 sec. after the fault is cleared
Record
Yes
Cause
Corrective Actions
Deceleration time too short
1. Increase the deceleration time
2. Increase the deceleration time of S-curve
3. Set auto-acceleration and auto-deceleration parameter (Pr.01-44)
4. Set over-current stall prevention function (Pr.06-03)
5. Replace the drive with a larger capacity model
Check if the mechanical brake of
the motor activates too early
Check the action timing of the mechanical brake
Short-circuit at motor output due to
poor insulation wiring
Check the motor cable and remove causes of the short circuits, or replace the
cable before turning on the power.
Check for possible burnout or
aging insulation of the motor
Check the motor insulation value with megger. Replace the motor if the
insulation is poor.
The load is too large
Check if the output current during the whole working process exceeds the AC
motor drive’s rated current. If yes, replace the AC motor drive with a larger
capacity model.
Impulsive change of the load
Reduce the load or increase the capacity of AC motor drive.
Use special motor or motor with
larger capacity than the drive
Check the motor capacity (the rated current on the motor’s nameplate should
≦
the rated current of the drive)
Use ON/OFF controller of an
electromagnetic contactor at the
output (U/V/W) of the drive
Check the action timing of the contactor and make sure it is not turned ON/OFF
when the drive outputs the voltage.
V/F curve setting error
Adjust V/F curve settings and frequency/voltage. When the fault occurs, and the
frequency voltage is too high, reduce the voltage.
Torque compensation is too large Adjust the torque compensation (refer to Pr.07-26 torque compensation gain)
until the output current reduces and the motor does not stall.
Malfunction caused by interference Verify the wiring of the control circuit and wiring/grounding of the main circuit to
prevent interference.
The length of motor cable is too
long
Increase AC motor drive’s capacity
Install AC reactor(s) on the output side (U/V/W)
Hardware error
The ocd occurs due to short circuit or ground fault at the output side of the drive.
Check for possible short circuits between terminals with the electric meter:
B1 corresponds to U, V and W; DC- corresponds to U, V and W;
corresponds to U, V and W.
If short circuits occur, return to the factory for repair.
Check if the setting of stall
prevention is correct
Set the stall prevention to the proper value.
