Stop and retract (ESR) - Drive-autonomous

The extended stop and retract (ESR) function - drive-autonomous offers the possibility of
flexibly responding when a fault situation occurs, irrespective of the higher-level control (NC):
For this purpose, the following axial functions can be configured in the drive:
Retract
Extended stop
Generator operation
The drive-autonomous responses are automatically initiated in fault situations. The triggering
of the drive-autonomous responses can also be realized user-specific via the part programs
or synchronized actions from the higher-level control. As the stopping and retraction motion
of the drive-autonomous ESR are purely axial, in contrast to the control-controlled ESR,
couplings are not taken into account.
Benefit
Faster, situation-conform stop and retraction of axes after a power failure
Stopping and retraction motions in the drives even when they can no longer be specified
from the control, e.g. as a result of a communication failure
Fast resumption of the part program thanks to the block search at the point of interruption
