Specific kv factor
for spindle
orientation
As the position control of the spindle is based on other internal algorithms than
the position control of the axes, it can be useful to set the control behavior of
the spindle so that it differs from that of the axes. The position control of the
spindle is calculated on the MC—this results in time offsets that can, under
certain circumstances, necessitate a reduction of the spindle's kv factor.
With the MP_kvFactorM19 parameter you can define a specific kv factor for
the oriented spindle stop. If M19 is active, the value defined in
CfgPosControl/kvFactor is replaced.
MP_kvFactorM19
kv factor for oriented spindle stop
Available from NCK software version: 597 110-05.
Format: Numerical value
Input: 0.000 to 1 000.000 [1/s]
Only effective with active spindle orientation (M19); replaces
the value in CfgPosControl/kvFactor.
If the parameter is not defined or 0, the value in
CfgPosControl/kvFactor is used.
Default: No value, parameter optional
Access: LEVEL3
Reaction: RUN
Spindle
Oriented spindle
stop with
stationary spindle
A ramp algorithm determines the acceleration with a stationary spindle.
MP_maxAcceleration determines the steepness of the ramp during
acceleration, MP_maxAcceleration determines the steepness of the ramp
during braking. The MP_maxFeed parameter or the speed from Module 9414
limits the ramp.
