
− DC bus undervoltage Mains voltage too low Check mains voltage
Voltage in DC−bus connection too low Check power supply module
400 V controller is connected to 240 V mains Connect controller to correct mains voltage
OC1
$
11 Short circuit Short circuit  Search for cause of short circuit; check motor cable
 Check brake resistor and cable to brake resistor
Capacitive charging current of the motor cable too
high
Use shorter/low−capacitance motor cable
OC2
$
12 Earth fault A motor phase has earth contact 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 inspection purposes
OC3
$
13 Controller overload during
acceleration or short circuit
Acceleration time set is too short (C0012)  Increase acceleration time
 Check drive dimensioning
Defective motor cable Check wiring
Interturn fault in the motor Check motor
OC4
$
14 Controller overload during
deceleration
Deceleration time set is too short (C0013)  Increase deceleration time
 Check dimensioning of the external brake resistor
OC5
$
15 Controller overload during
steady−state operation
Frequent and too long overload Check drive dimensioning
OC6
$
16 Motor overload (I
2
x t overload) Motor is thermally overload by e.g.
 impermissible continuous current  Check drive dimensioning
 frequent or too long acceleration processes  Check setting of C0120
OH
$
50 Heatsink temperature
> +85 °C
Ambient temperature is too high Allow controller to cool and provide better ventilation
OH
#
− Heatsink temperature
> +80 °C
Heatsink is very dirty Clean heatsink
Impermissibly high currents or frequent and too
long acceleration processes
 Check drive dimensioning
 Check load, exchange rough−running, defective
bearings if necessary
OH3
$
53 PTC monitoring (TRIP)
(Display when C0119 = 1 or 4)
Motor too hot due to impermissibly high currents
or frequent and too long acceleration processes
Check drive dimensioning
No PTC connected Connect PTC or switch off monitoring
OH4
$
54 Controller overtemperature Controller too hot inside  Reduce controller load
 Improve cooling
 Check fan in the controller
OH51
203 PTC monitoring
(Display when C0119 = 2 or 5)
Motor too hot due to impermissibly high currents
or frequent and too long acceleration processes
Check drive dimensioning
No PTC connected Connect PTC or switch off monitoring
OU

− DC bus overvoltage
(Message or TRIP configurable
in C0310)
Mains voltage too high Check supply voltage
OUE
$
22 Braking operation  Increase deceleration times
 When operating with an external brake resistor:
– Check dimensioning, connection and supply cable
of the brake resistor
– Increase deceleration times
Earth leakage on the motor side Check motor supply cable and motor for earth fault
(disconnect motor from the inverter)
