The speed for traversing the reference mark is defined in the module.
The spindle must be started from a standstill to traverse the reference mark.
If the spindle is started for reference mark traverse, marker M4018 is set.

<Axis/spindle>
Axis-specific: Dependence on MP4020 bit 14
PS B/W/D/K <Feed rate/shaft speed>
0: Feed rate MP1330.x
>0: Feed rate in mm/min or shaft speed in 1/1000 min
–1
PS B/W/D/K <Direction of traverse>
–1: Negative direction
0: Direction from MP1320.x
1: Positive direction
CM 9220
PL B/W/D <Error code>
0: Reference mark traverse is commanded
1: Non-existent axis or open-loop spindle
2: Inadmissible values for the feed rate / direction
4: Reference traverse not possible because reference
traverse already started
5: Axis is already being positioned or the spindle is in motion
6: Other axis is already being positioned
7: PLC positioning has already been commanded
8: Programmed axis not in closed loop
Error code:
