For speed controller adjustment, increase the gain until vibrations occur. Then slowly
reduce the gain until the drive stops vibrating. After this, reduce the time constant until
vibrations occur. Then slowly increase the time constant until the controller is stable and
stiff with setpoint = 0.
Case 1: Too soft speed controller setting
Remedy:
z
Increase the gain factor by 2 to 3 tenth of a point
z
Reduce the time constant by 1 to 2 msec
Case 2: Too hard speed controller setting
Remedy:
z
Reduce the gain factor by 2 to 3 tenth of a point
z
Increase the time constant by 1 to 2 msec
Case 3: Correct speed controller setting
