Use MP1087.x to limit the axis-specific jerk in Manual mode.
For unfiltered positioning movements, such as PLC positioning movements
or positioning movements in measuring cycles, MP1088.x can be used to
define axis-specific jerk limitation.
Use MP1089.x to limit the axis-specific jerk in the Pass Over Reference
Point mode of operation. This is necessary if you want to brake or
accelerate faster in this operating mode than in other operating modes.

At high feed rates (e.g. rapid traverse) a higher jerk is permitted than at low
feed rates:
Enter the jerk for low feed rates in MP1090.0, and for high feed rates in
MP1090.1. MP1090.x is the jerk on the tool path. The input value is
determined by the weakest axis.
With MP1090.x you can limit the path jerk that results from MP1085.x or
MP1086.x. MP1090.0 takes effect for movements not at FMAX or if the
feed rate is less than the value in MP1092. MP1090.1 takes effect for
movements at FMAX or if the feed rate is greater than the value in MP1092.
This limitation can be switched off by entering the value 0 in MP1090.x.
With MP1092 you specify a feed-rate threshold for the various jerk
parameters in MP1085.x and MP1086.x.
If the programmed feed rate is less than the value in MP1092, the
parameters in MP1085.x apply. If the programmed feed rate is greater than
the value in MP1092, the parameters in MP1086.x apply. This way you have
the same behavior as previously for all axes via MP1090.0 and MP1090.1.
Enter the value 0 in MP1092 to deactivate this feed-rate limit. Then the jerk
parameters from MP1085.x apply to movements not at rapid traverse. The
values in MP1086.x become active for movements at FMAX.
