• The dynamic limits of the axis stored in the machine data are applicable in axis operation.
• The axis switches to the current feedforward control mode as designated by the MD and
the commands FFWON and FFWOF.

• When using resolution changes in (analog) drive actuators, the following NC program
steps are required:
Table 2-1 Change over to axis mode:
SPOS=...
M5 Closed-loop controller enable off (by PLC)
→ Output to PLC
M70 Switch actuator (by PLC on account of M70)
Closed-loop controller enable on (by PLC)
C=... NC travels with axis parameter set
Table 2-2 Switch back to spindle mode
C=...
M71 → Output to PLC
Closed-loop controller enable off (by PLC)
Switch actuator (by PLC)
Switched to spindle parameter set (1-5) internally in the NC,
controller enable on (by PLC)
M3/4/5
or
SPOS=...
NC travels with spindle parameter set
