− DC−bus undervoltage Mains voltage is too low Check mains voltage
Voltage in DC−bus connection is too
low Check power supply module
400 V controller is connected to 240 V
mains Connect controller to correct mains voltage
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 is too high Use shorter/low−capacitance motor cable
OC2
a
12 Earth fault A motor phase has earth contact Check motor; check motor cable
Capacitive charging current of the
motor cable is 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 Set acceleration time 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 Set deceleration time 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 periods 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

processes l Check drive dimensioning
l Check load, replace rough−running,
defective bearings, if necessary

53 PTC monitoring (TRIP)
(display when
C0119 = 1 or 4) Motor too hot due to impermissible
high currents or frequent and too long
acceleration processes Check drive dimensioning

overtemperature Controller is too hot inside l Reduce controller load
l Improve cooling
l Check fan in the controller
