• In JOG mode if Spindle Jog key pressed as with
M41
smallest speed is activated
In JOG mode Spindle speed >> key and spindle speed<<
key control an internal pointer for changing the speed
stages as in AUTO mode

---->> Speed stage 2 (identical toM42)
Speed stage 3 (identical to M43)
Speed stage 4 (identical to M44)

Toolholder control
S Input signals:
I0.0, I0.1, I0.2, I0.3, I0.4, I0.5 toolholder locations
I0.6 toolholder “Positioned”
T function (tool number) in the part program
Manual tool change on the machine control panel (C4)
S Output signals:
Toolholder CW (O0.4)
Toolholder CCW (O0.5)
S UPGMTURN control
Precondition Result
S In AUTO mode T (0<= T <=5) is not identi-
cal to the current toolholder position
S Toolholder CW is active as long as the se-
lected toolholder position is detected on the
inputs; then Toolholder CCW is active for
the interval set in the PLC MD.
S In JOG mode Manual Tool Change key
pressed down
S Toolholder CW is active as long as the key
is pressed down.
