Commutation and Speed:
The commutation (angle) refers to
 A pole-pair width of 25 mm with linear encoders; i.e. 0° to 360° are displayed within
25 mm.
 A pole-pair width of 1 with rotary or angle encoders; i.e. 0° to 360° are covered in one
revolution.
For linear encoders, the displayed speed is the traversing speed, for rotary encoders the spindle
speed.
Encoders with a DRIVE-CLiQ interface compute these values in the encoder and then transfer
them to the interface.
External temperature sensor
Display of the temperature of an external temperature sensor, if supported by the encoder (e.g.
the temperature of the winding). An extremely high or low value indicates that no temperature
sensor is connected; see the temperature in the illustration.
