Description of the Software Modules and Parameters
Kt correction factor
Production-technical deviations of the motor Kt can be corrected by a comparison mea-
surement (dynamo electric machine) by the correction factor, Kt
having to adjust the measuring data of the motor.

4.7.7.5 Ks adaption

The "system gain" can be deviated from the measuring point value (ASM field weakening,
changing load inertia). This can either be considered in the parameter "Ks actual"

value can be adapted as follows accordant to the flux actual value and the change in the
inertia torque of the drive:
with:
The Ks adaption is significant to the following:
The magnetic flux is dependent of the saturation influence at the ASM (see
the Saturation–
Cyclic Ks adaption
The torque of inertia changes at some applications. This requires a cyclical change of the
Ks factor and can be adapted via the control and parameter Z155.14–.
The cyclic Ks adaption is not active. It is activated by (controller adaption) mode
bit 4.
The Ks value is updated in RT1 cycle.
