6.6.2.2

Parameterising slip compensation

The slip compensation serves to automatically compensate a load-dependent speed loss. In order

that the slip compensation can operate correctly, the rated slip of the motor is required. This is

calculated from the rated frequency (

C00089

) and the rated speed (

C00087

), thus both parameters

must be parameterised correctly.

• A percentage adjustment of the calculated slip can be made in

C00965

, e.g. when the real motor

data deviate from the data given on the nameplate. A value of 100 % in

C00965

corresponds to

the rated slip of the machine.

• The time behaviour of the slip compensation can be parameterised in

C00966

.
