; 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)
The drive is connected to the
coasting machine. The coasting is
caused by a short−time pulse
inhibit, e.g. at
l OU (overvoltage in the DC bus)
l external or internal controller
inhibit
l Activate flying restart circuit
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 35
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 36, "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.
