MP_maxAccSpeedCtrl
Optional acceleration for the spindle with shaft speed control
Available from NCK software version: 597 110-03.
Format: Numerical value
Input: 0.000 000 000 to 1000 [1000°/s
2
]
This parameter is only effective for spindles. If 0 is entered or
there is no parameter, the acceleration from
MP_maxAcceleration is used.
Default: No value, parameter optional
Access: LEVEL3
Reaction: RUN
MP_maxDecSpeedCtrl
Optional braking ramp for the spindle with shaft speed control
Available from NCK software version: 597 110-03.
Format: Numerical value
Input: 0.000 000 000 to 1000 [1000°/s
2
]
This parameter is only effective for spindles. If the value 0 is
entered or the parameter is not available, the value from
MP_maxAccSpeedCtrl will be used for the brake acceleration.
If MP_maxAccSpeedCtrl is also 0 or not present, the value
from MP_maxAcceleration will be used.
Default: No value, parameter optional
Access: LEVEL3
Reaction: RUN
There are two ways to configure the maximum jerk on the path:
MP_maxPathJerk(Hi) (829) limits the jerk in the direction of traverse.
MP_axTransJerk limits the jerk for specific axes in the transverse path
direction (transition jerk).
If the emphasis of commissioning is primarily on speed (with a sufficiently
smooth surface), you can set the transition jerk to a value that is 2 to 3 times
higher than the path jerk. Only if a smooth surface takes highest priority should
you use the same setting for both the path jerk and the transition jerk.
MP_axTransJerk
Maximum axis jerk
Available from NCK software version: 597 110-01.

Default: 0.1 [m/s
