288 Parameters
Set zero pos Sets the zero position of angle offset to the encoder
memory. Parameter 90.06 ENC PAR REFRESH
must be selected to activate the writing procedure to
the encoder.
Note: This selection is supported with FEN-11
(EnDat and Hiperface).

99.13 SLIP GAIN Defines the slip gain which is used to improve the estimated
motor slip. 100% means full slip gain; 0% means no slip
gain. The default value is 100%. Other values can be used if
a static speed error is detected despite of the full slip gain.
Example (with nominal load and nominal slip of 40 rpm): A
1000 rpm constant speed reference is given to the drive.
Despite of the full slip gain (= 100%), a manual tachometer
measurement from the motor axis gives a speed value of
998 rpm.
The static speed error is 1000 rpm - 998 rpm = 2 rpm.
Error can be compensated by increasing slip gain. At 105%
gain value, no static speed error exists (2 rpm / 40 rpm =
5%).
100% / Real
0…200% Slip gain. -
