Lenze SMD Series User Manual

32
Error Cause Remedy
(1)
0C1
Short-circuit or overload Short-circuit Find reason for short-circuit; check
motor cable
Excessive capacitive charging
current of the motor cable
Use shorter motor cables with lower
charging current
Acceleration time (C12) too short • Increase acceleration time
• Check controller selection
Defective motor cable Check wiring
Internal fault in motor Check motor
Frequent and long overload Check controller selection
0C2
Earth fault Grounded motor phase Check motor/motor cable
Excessive capacitive charging
current of the motor cable
Use shorter motor cables with lower
charging current
0C6
Motor overload (I
2
t overload) Motor is thermally overloaded,
due to:
• impermissable continuous current
• frequent or too long acceleration
processes
• Check controller selection
• Check setting of c20
0H
Controller overtemperature Controller too hot inside • Reduce controller load
• Improve cooling
OU
Overvoltage on DC bus Mains voltage too high Check mains voltage
Excessively short deceleration time
or motor in generator mode
Increase deceleration time or use
dynamic braking option
Earth leakage on the motor side Check motor/motor cable
(separate motor from controller)
rSt
Faulty auto-TRIP reset More than 8 errors in 10 minutes Depends on the error
SF
Single phase fault A mains phase has been lost Check mains voltage
(1) The drive can only be restarted if the error message has been reset; see c70
