Drift Compensation － Drift Potentiometer; Tachometer －Potentiometer - Siemens SIMODRIVE base line A Technical Manual

Installation
2.6.1.5. Drift compensation － Drift potentiometer
General
2.6.1.6. Tachometer －Potentiometer
Setting range
2-14
The drift is compensated for n
Control range: +/-45mV.
The actual drive speed for +/-10V speed setpoint can be varied by the
rated speed in the range: 0.6 n
The following setting ranges are obtained for a ± 10V speed setpoint
according to the rated speeds.

When the speed setpoint is reduced, the setting range is also
appropriately reduced. We recommend that the motors with a rated
speed of 2250 RPM are operated using a ± 9V speed setpoint, in order
to limit the selectable maximum speed.
