Signal(s) updated: cyclic
The control is in the reset mode (reset key or end of program)
The axis was last programmed as a positioning axis or positioning spindle (initial setting of
supplementary axis: Positioning axis)
The path movement was stopped with NC Stop
The spindle is in the closed-loop position-controlled mode (SPCON/SPOS instruction) and is
stationary
The axis is switched from closed-loop speed-controlled to closed-loop position-controlled mode
with IS "position measuring system"
The path movement was stopped with NC Stop
The spindle is in the closed-loop speed-controlled mode (SPCOF/SPOSA instruction)
The "follow-up" mode is active for the axis
The "parking" mode is active for the axis
The axis is switched from closed-loop position-controlled to closed-loop speed-controlled mode
with IS "position measuring system"
Signal(s) updated: cyclic
