OC1
a
11 Short circuit Short circuit l Search for cause of short circuit; check
motor cable
l Check brake resistor and cable to brake
resistor
Capacitive charging current of the
motor cable too high Use shorter/low−capacitance motor cable
OC2
a
12 Earth fault Earthed motor phase Check motor; check motor cable
Capacitive charging current of the
motor cable too high Use shorter/low−capacitance motor cable
Deactivate earth−fault detection for test
purposes
OC3
a
13 Controller overload
during acceleration or
short circuit Acceleration time set is too short
(C0012) l Increase acceleration time
l Check drive dimensioning
Defective motor cable Check wiring
Interturn fault in the motor Check motor
OC4
a
14 Controller overload
during deceleration Deceleration time set is too short
(C0013) l Increase deceleration time
l Check dimensioning of the external brake
resistor
OC5
a
15 Controller overload
during steady−state
operation Frequent and too long overload Check drive dimensioning
OC6
a
16 Motor overload
(I
2 x t overload)
Motor is thermally overloaded by e.g.
l impermissible continuous current l Check drive dimensioning
l frequent or too long acceleration
processes l Check setting of C0120
