The following behavior may indicate that the controller parameters are not config-
ured properly:
drive is very loud
drive vibrates
frequent contouring errors
inexact control
For the setting options of other control parameters, e.g. speed controller and accel-
eration pilot control, refer to the operating instructions of the frequency inverter.
Note: Optimize the settings in actual operating conditions, as control parame-
ters for speed controller and acceleration pilot control depend on actual
load. Optimize with different load types to obtain a good control behav-
ior in all situations.
