Inverter Troubleshooting And Fault Information
：
DISPLAY ERROR CAUSE REMEDY
OC-S
Over current at
start 1. the motor wind and enclosure
short circuit
2. the motor contacts and earth
short circuit
3. the IGBT module ruined
1.inspect the motor
2.inspect the wire
3.replace the transistor module
OC-A
Over-current at
acceleration 1. Acceleration time too short
2. The capacity of the motor higher
than the capacity of the inverter
3. Short circuit between the motor
coil and the shell
4. Short circuit between motor
wiring and earth
5. IGBT module damaged
1. Set a longer acceleration time
2. Replace a inverter with the same
capacity as that of the motor
3. Check the motor
4. Check the wiring
5. Replace the IGBT module
OC-C
Over-current at
fixed speed 1. Transient load change
2. Transient power change
1.Increase the capacity of the
inverter
2.Rerun parameter auto tuning
(0-06 = 1)
3. Reduce stator resistance (14-0)
if the above remedies are helpless
OC-D
Over-current at
deceleration The preset deceleration time is
too short.
Set a longer deceleration time
OV-C
Voltage too high
during operation/
deceleration 1. Deceleration time setting too short
or large load inertia
2. Power voltage varies widely
1. Set a longer deceleration time
2. Add a brake resistor or brake
module
3. Add a reactor at the power input
side
4. Increase inverter capacity
LV-C
Voltage too low
during operation 1. Power voltage too low
2. Power voltage varies widely 1. Improve power quality or
increase the value of 2-01
2. Set a longer acceleration time
3. Increase inverter capacitor
4. Add a reactor at the power input
side
OH-C
Heat sink
Temperature too
High during
Operation 1. Heavy load
2. Ambient temperature too
high or bad ventilation
1. Check if there are any problems
with the load
2. Increase inverter capacity
3. Improve ventilation conditions
