ESR is enabled via system variable

The ESR response of an axis, configured via drive parameter, must be programmed on a
user-specific basis in a part program/synchronized action using the following axis-specific
system variable:
$AA_ESR_ENABLE[<axis>]
Value
1
0
6.3.6

Triggering ESR via system variable

Triggering ESR responses, configured via drive parameter and enabled via
$AA_ESR_ENABLE[<axis>], must be programmed on a user-specific basis in a part program/
synchronized action via the following NC-specific system variable:
$AN_ESR_TRIGGER
Value
1
0
388
Description
Speed threshold value 3
Speed threshold value for the message: |n_act| < speed threshold value 3
Meaning
ESR responses enabled in the drive
ESR responses inhibited in the drive
Meaning
trigger drive-integrated ESR reactions that have been released
do not trigger drive-integrated ESR reactions that have been released
