Operating of the unit
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
Slip compensation balances the speed changes caused by the load variation. In
order to activate the function, set the value to 1.00 and optimize as directed in the
examples below.
Adjustment range:
-2.50...2.50
Resolution:
0.01
Factory setting:
0.00 (=off)
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.
Adjustment range:
-2.50...2.50
Resolution:
0.01
Factory setting:
0.00 (=off)
Customer adjustment:
_______
Slip compensation and autoboost work on the basis of presetting motor
data. When using a special motor or in case of overdimensioning by more
than one size, both functions should be deactivated.
