1) good - speed remains stable at increasing torque
2) bad - speed decreases with increasing torque
3) bad - speed is increased too much at load
Slip compensation balances the speed changes caused by the load
variation. In order to activate the function, set the value at 1.00 and
optimize as directed in the examples below.

Customer adjustment:
Autoboost causes an automatic I*R-compensation by raising the output
voltage during high load torques. The magnetizing current remains
constant. To activate the function set the value to 1.00 and optimize as
directed in the examples below. Check the motor voltage to see, whether
it returned to the normal value after no load of the drive. Otherwise reduce
CP.19.

Customer adjustment:
Slip compensation and autoboost work on the basis of preset
motor data. When
overdimensioning of more than one size, then both functions
should be deactivated.
