Nominal speed
value
In MP3411.x, define the ramp gradient for the nominal speed value at M03
and M04 for each gear range.
With MP3412.0, specify a multiplication factor for MP3411.x, for
• M05 (MP3412.0)
• SPINDLE ORIENTATION (MP3412.1)
• TAPPING (with floating tap holder) (MP3412.2)
• RIGID TAPPING (without floating tap holder) (MP3412.3)
The same factor applies for all gear ranges.
Set MP3411 for M03, M04 and M05 such that the motor accelerates and
brakes within the current limit.
With MP3415, define the overshoot behavior for every operating mode
when the spindle is switched on with M4011. Set MP3415.0 so that only
one overshoot is visible.
If the nominal speed value is in the acceleration or deceleration ramp, then
M4001 is reset. This also applies if the speed is changed with the override
potentiometer.
If the nominal speed value is output as zero, M4002 is set.
In machine parameter MP7440 bit 7 = 1 you can define for the M function M0
that the internal geometry status is not to change to M05. The status M03/
M04 is retained in the geometry. The spindle status in Q110 is also not
influenced by M0 if bit 7 is set. Thus the processing of cycles does not result
in the error message "Spindle ?" after an NC start.

MP7440 bit 7 may only be set if after an M00, an NC start is absolutely
required by the PLC program to start the spindle again. Otherwise it is
possible that the spindle starts when the user does not expect it.
