Reactions
For time T1 the speed setpoint that was active when
the error occurred is still output. This is an attempt to
maintain the movement that was active before the
failure until the physical contact is annulled or the
retraction movement initiated simultaneously in other
drives is completed. This can be necessary for all
leading/following drives or for drives that are coupled
or in a grouping.

T1
After time T1, all axes with speed setpoint
feedforward zero are stopped at the current limit,
and the pulses are deleted when zero speed is
reached or when the time has expired (+ drive MD).
13.5.7 Drive-independent retract
Function
Axes with digital 611D drives can (if configured and
released) also execute a retraction movement
independently
•
at control failure (sign-of-life detection)
•
if the DC link voltage falls below a warning
threshold
•
if triggered by the system variable
$AN_ESR_TRIGGER.
The retraction movement is performed
independently by drive 611D.
Once the retraction phase is initiated, the drive
independently maintains its enables at the values
that were previously valid.
