1) good - speed remains stable at rising torque
2) bad - speed decreases with rising torque
3) bad - speed is raised too much under load

Slip compensation compensates the speed changes caused by load changes. To
activate the function, adjust a value of approx. 1.00 and optimize it according to the
examples below.

Customer setting:
In case of high load torques Autoboost causes an automatic I*R-compensation by
raising the output voltage. The magnetizing current remains nearly constant. To activate
the function, adjust a value of approx. 1.00 and optimize it according to the example.
Check, whether the motor voltage is taken back when the load on the drive is reduced.
If not, reduce the value of CP.19.

Customer setting:
Slip compensation and Autoboost work on the basis of preadjusted motor
data. When employing a special motor or in case of overdimensioning by
more than one size both functions should be deactivated.
