Drive performance
Rough motor run and motor current (C0054) > 60 %
rated motor current in idle running (stationary
operation)
Torque too low for frequencies f < 5 Hz (starting
torque)
Poor constant speed at high loads (setpoint and motor
speed are not proportional).
Error messages OC1, OC3, OC4 or OC5 during
acceleration times (C0012) < 1 s (drive controller is no
longer able to follow the dynamic processes)

Remedy
1. Reduction of motor inductance (C0092) by 10 %
2. Check of motor current under C0054
3. If the motor current (C0054) > 50 % of the rated
motor current:
– C0092 must be reduced until the motor current
amounts to 50 % of the rated motor current
– Reduce C0092 by max. 20 %!
– Note: If you reduce C0092 the torque will
decrease!
Increase of motor resistance (C0084) or increase of
motor inductance (C0092)
Increase of slip compensation (C0021)
Overcompensation results in drive instability!
Change reset time of the I
Reduction of C0078 = I
quicker (more dynamic)
Increase of C0078 = I
slower ("smoother")
