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

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

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
No PTC connected
Connect PTC or switch off monitoring
