Activation of the F values
Machine data:
MD22140 F_VALUES_ACTIVE_AFTER_RESET (F function active via RESET)
can be used to define whether the following most recently programmed F values are to remain active following a
RESET.
• Programmed path feedrate: F=...
• Programmed feedrate change for path feedrate: OVR=...
• Programmed positioning feedrate: FA=...
• Programmed feedrate change for positioning feedrate: OVRA[U]=...

Position spindle
If G95,G96,G961,G97,G971,G33,G34,G35 is active, spindle positioning should not be performed, because
the derived path feedrate following spindle positioning = 0.
⇒ If the programmed axis position has not yet been reached, the block cannot be completed.
