13.4 Error Code
13.4.1 Error 1 (OC-1): Overcurrent at Constant Speed
Possible reason
Solution
Sudden load change in run mode
Reduce occurrence and scale of sudden change
Low mains voltage
Check input power supply
Motor power and frequency converter
power do not match
Motor power has to match with frequency converter power
Excessive inertia or load
Check power of motor and frequency converter, check load
The motor cable is too long
● Decrease the carrier frequency (C0.05)
● Use a frequency converter with larger power
Excessive torque compensation
Reduce torque compensation setting (C2.22) till the current
decreases
Excessive overexcitation braking factor Reduce [E0.55]
13.4.2 Error 2 (OC-2): Overcurrent during Acceleration
Possible reason
Solution
Excessively short acceleration time
Increase acceleration time (E0.26)
Excessive start-up frequency
Reduce start frequency (E0.36)
Excessive load rotation inertia or impact Increase acceleration time (E0.26), reduce sudden load
change
Running command active while motor is
coasting
Restart after motor stop or start with speed capture (E0.35)
Wrong setting of V/f curve related pa-
rameters
Adjust setting of V/f curve related parameters
Motor power and frequency converter
power do not match
Motor power has to match with frequency converter power
Excessive torque compensation
Reduce torque compensation setting (C2.22) till the current
decreases
Wrong motor parameters setting
Correct motor parameters setting
Excessive overexcitation braking factor Reduce [E0.55]
13.4.3 Error 3 (OC-3): Overcurrent during Deceleration
Possible reason
Solution
Excessively short deceleration time
Increase deceleration time (E0.27)
Excessive load rotation inertia
Use suitable brake components
Motor power and frequency converter
power do not match
Motor power has to match with frequency converter power
