Motor model settings.
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 having the setting at 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 having 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. To
compensate the error, the slip gain should be increased to
105% (2 rpm / 40 rpm = 5%).
