MD32402 $MA_AX_JERK_MODE
MD32410 $MA_AX_JERK_TIME
MD32400 $MA_AX_JERK_ENABLE
If no filter mode previously:
MD32402 $MA_AX_JERK_MODE = 2
was activated, then "Power On" must be initiated once.
Otherwise, "Enable machine data" or "Reset" at the machine control panel are sufficient.
Note
Generally, the filter is set using:
MD32402 $MA_AX_JERK_MODE = 2
Fine adjustment
The fine adjustment of the jerk filter is carried out as follows:
1. Assess the traversing response of the axis
(e.g., based on positioning processes with servo trace).
2. Modify the filter time in MD32410 $MA_AX_JERK_TIME.
3. Activate the modified time via "Enable machine data" or RESET on the machine control panel.
Disabling
Disabling the jerk filter:
1. Disable filter calculation:
MD32410 $MA_AX_JERK_ENABLE = 0.
2. Activate the interlock via "Enable machine data" or RESET on the machine control panel.
