Figure 7-17 Activated jerk limitation
The maximum inclination (r
k
) can be set in parameter p2574 ("Jerk limitation") in the unit
LU/s
3
for both acceleration and braking. The resolution is 1000 LU/s
3
. To activate limiting
permanently, set parameter p2575 ("Active jerk limitation") to 1. In this case, limitation
cannot be activated or deactivated in traversing block mode by means of the command
"JERK" as this would require parameter p2575 ("Activate jerk limitation") to be set to zero.
The status signal r2684.6 ("Jerk limitation active") indicates whether or not jerk limitation is
active.
Limitation is effective:
● In jog mode
● When traversing blocks are processed
● When setpoints are defined directly/MDI for positioning and setup
● during referencing
● During stop responses due to alarms
Jerk limitation is not active when alarms occur with stop responses OFF1 / OFF2 / OFF3.
