2.14 2.14 Path jerk for real-time events (channel-specific)
2.14.1 Detailed description
2.14.1.1 General information
Key statement
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
• Feedrate override modifications
• Modification of the velocity default for "safely reduced velocity" within the context of the
"Safely Integrated" function
the path jerk can be set for the real-time events specified above using a channel-specific
system variable:
$AC_PATHJERK =
path jerk
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.
