MP_M19MaxSpeed
Maximum rotational speed limit for M19
Available from NCK software version: 597 110-01.
Format: Numerical value
Input: 100 to 20 000 [1/min]
Default: 1 000 [1/min]
Access: LEVEL3
Reaction: RUN
For a spindle orientation requested by the NC (tapping, measuring) the
parameter MP_M19NcSpeed (400310) can now be used to specify the speed
for it.
MP_M19NcSpeed
Nominal speed for an oriented spindle stop commanded by the
NC
Available from NCK software version: 597 110-03.
Format: Numerical value
Input: Shaft speed [rpm]
Default: No value, parameter optional
Access: LEVEL3
Reaction: RUN
Make sure that the rotational speed limit is not set too low. Otherwise, due
to the position-controller cycle time it will be impossible to generate jerk-
limited positioning commands.
HEIDENHAIN recommends the following for the setting of
MP_M19MaxSpeed:
Set a minimum of 3000 rpm for dynamic milling spindles.
For slower milling spindles set a minimum of 1000 rpm.
The absolute minimum for the input value of MP_M19MaxSpeed is 100
rpm.
