Path jerk for real-time events (channel-specific)

5.2.14.1

General Information

Overview
So that no compromise has to be made between machining-optimized jerk on the one hand
and time-optimized jerk in connection with the following real-time events on the other:
● NC Stop / NC Start
● Changing the feedrate override
● Changing the velocity default for "safely reduced velocity" within the context of the "Safety
Integrated" function
for the real-time events mentioned, the path jerk can be specified using a channel-specific
system variable:
$AC_PATHJERK =
Path jerk for real-time events will only be active for the duration of the change in velocity in
respect of one of the real-time events specified above.
Limitation
As the jerk is not a physical variable of any relevance to the drive, no limit is imposed on the
jerk set.
