nErr x190 Difference between
actual speed and speed
setpoint exceeds set
tolerance limits (C0576).
1. Motor torque not high enough
2. Mechanical drive overload
3. Error in encoder system / speed encoder defective
4. Tolerance too low (C0576)
1. Check limit values
2. Reduce mechanical load / adapt setpoint and
quick stop ramp
3. Check speed encoder and replace if necessary
4. Increase tolerance window . The nErr window
should be at least twice as big as for normal
operation.
•
TIP: If you want to monitor the speed encoder,
the error response should be set as TRIP.
OC1 x011 Short circuit
Short-circuit. Find out cause of short-circuit; check cable.
Excessive capacitive charging current of the motor
cable.
Use motor cable which is shorter or of lower
capacitance.

x154 Negative position limit Negative position limit (C1224) was not reached. Find out why the value was not reached (e.g.
”incorrect” position targets, set function position
value) and adjust the negative position limit
(C1224) if necessary.
