Extended stop and retract

Overview
The "extended stop and retract" function module (ESR) allows a workpiece and tool to be
separated without causing any damage when a fault situation occurs. The drive axes
involved are defined and are retracted and/or stopped in a controlled fashion. For this
function, the drives must be operated in the SERVO control mode.
The drive-integrated ESR functions are described in this manual:
1. Extended stopping of the drive
2. Extended retraction of the drive
3. Generator operation with monitoring to buffer the DC link voltage
ESR functions can be initiated from the higher-level control using a trigger signal, or
independently in the drives themselves in the event of a fault (the function is integrated in the
drive). The ESR functions integrated in the drive act on an axis-for-axis basis.
● Using an axis-specific trigger, ESR functions are directly initiated for an individual axis.
● Using a local trigger on the device itself, the ESR functions are simultaneously initiated

for those axes under the drive line that are activated for ESR.
NOTICE
ESR functionality under Safety Integrated Functions
If extended stop and retract are to activated simultaneously with Safety Integrated
Functions, the following conditions must also be satisfied. Further information can be
found in the SINAMICS S120 Safety Integrated Function Manual.
