Overflow after the number of revolutions entered in P1021 (multiturn reso-
lution, motor absolute value encoder).
For linear axis with encoder connected to the motor, the following is valid:
––> The maximum traversing travel is: P1021  effective spindle pitch
Example: EQN 1325, 10 mm spindle pitch
––> max. traversing distance = –20.48 m to 20.48 m
 The machine zero can be completely freely selected in the
range from –20.48 m to +20.48 m.
