0011 OC1 Overcurrent in motor cable
(I

N
; Hardware
monitoring)
In the event of a short circuit. l Search for the cause of the
short circuit.
l Check the motor cable.
Capacitive charging current of the
motor cable is too high.
Use motor cable which is shorter
or of lower capacitance.
Too short acceleration or
deceleration times in proportion
to the load (C0012, C0013,
C0105).
l Increase the gain (P
component) of the Imax
controller (C0075).
l Reduce integral−action time
(integral action component) of
the Imax controller (C0076).
l Encoder error
l Tracks during encoder
feedback of the motor speed
are interchanged.
Check wiring of the encoder.
DC−injection braking at high
speeds.
l See 9.4−1
Missing mains phase. l Check the connections and the
supply cable of the device.
l Check mains voltage.
0012 OC2 Motor cable earth fault One of the motor phases has
earth contact.
l Search for cause of short
circuit.
l Check motor cable.
0013 OC3 Overload during acceleration. Too short acceleration or
deceleration times in proportion
to the load (C0012, C0013,
C0105).
l Increase the gain (P
component) of the current
controller (C0075).
l Reduce the reset time (integral
action component) of the I
max
controller (C0076).
l Increase ramp times.
l 9.4−2, "controller in clamp
operation (fault OC3)"
0015 OC5 I x t overload l Frequent and too long
acceleration with overcurrent
l Continuous overload with
I
motor
> 1.05 x I
rx.
Check drive dimensioning.
2020 OU Overvoltage in the DC bus Braking energy is too high.
(DC−bus voltage is higher than set
in C0173.)
l Use a braking unit or
regenerative module.
l Check dimensioning of the
brake resistor.
1030 LU Undervoltage in the DC bus DC bus voltage is lower than
specified in C0173.
l Check mains voltage
l Check supply cable
