Entering new jerk filter

FIR low pass (dynamic mode)
Requirement:
The maximum axial jerk for a path movement in MD32431 $MA_MAX_AX_JERK lies in the
range of 5 ... 500 m/s
21900 is pending for the affected axis.
Entering a new jerk filter:
Depending on the dynamic response mode, enter the following value for the selected axis:
● Frequency in the range from 10 ... 100 Hz
● Tolerance (only for linear axes) in the range of 0 to 0.05 mm
The following machine data is set active with the "Accept" softkey:
MD32400 $MA_AX_JERK_ENABLE = 1
MD32405 $MA_CALCFIR_FREQ
MD32406 $MA_CALCFIR_TOL
MD32404 $MA_CALCFIR_SELECT
Use the "Change" softkey to adjust the parameters of the jerk filter.
Use "Reset (po)" to activate the filter type in the following axis machine data:
MD32402 $MA_AX_JERK_MODE = x5 in the 1st position setpoint filter ladder
MD32402 $MA_AX_JERK_MODE = 5x in the 2nd position setpoint filter ladder
⇒ Additional actions:
● Press the "Cancel" softkey to cancel the inputs.
● Use the "Accept" softkey to accept the entries for the jerk filter.
