Nominal speed
value in open-loop
control
December 2001
In the SPINDLE ORIENTATION mode of operation, the nominal speed value is
controlled in a closed loop. In all other modes it is in an open loop.
The actual speed value of the spindle is not checked.

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 M03, M04 and M05 MP3411 so that the motor accelerates and brakes
within the current limit.

With MP3415, define the overshoot behavior for every operating mode. Set
MP3415.0 so that only one overshoot is visible.
Note
As of NC software 280 476-05, MP3415.0 only influences the overshoot
behavior when the spindle is switched on with M4011, but no longer with
M4009 or M4010.
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.
