ESR response in the event of a communication error

The response of the SINAMICS S120 drive in the case of a communication error when the
"Extended stop and retract (ESR)" function module is simultaneously enabled is described in
the following.
Requirement
● The Safety Integrated Extended Functions are controlled via PROFIsafe
● The function module "Extended stop and retract" is activated and enabled
Communication failure
Under communication failure in this context, we understand one of the following possibilities:
● Interruption/fault of the PROFINET connection for control via PROFIsafe
● STOP response of the F-PLC
Drive response
In the event of a communication failure, SINAMICS S120 makes a distinction between the
following responses:
● If p9580 ≠ 0 and ESR has been enabled, in the event of a communication failure, the
parameterized ESR response is realized.
● If p9580 ≠ 0 and SLS is active, in the event of communication failure, the parameterized ESR
reaction is only realized if, as SLS response, a STOP with delayed pulse cancellation when
the bus fails has been parameterized (p9563[0...3] ≥ 10).
● If p9580 ≠ 0 and SDI is active, in the event of communication failure, the parameterized ESR
reaction is only realized if, as SDI response, a STOP with delayed pulse cancellation when
the bus fails has been parameterized (p9566[0...3] ≥ 10).
● If p9580 ≠ 0 and SLP is active, in the event of communication failure, the parameterized ESR
reaction is only realized if, as SLP response, a STOP with delayed pulse cancellation when
the bus fails has been parameterized (p9562[0...1] ≥ 10).
Note
Maximum response time for interruption in communication
When a safety-relevant communication is interrupted, Safety Integrated only permits a
response time (p9580) of max. 800 ms. The drive changes into the "fail safe state" once this
time expires. In this case, S_STW1/2 is assumed to be 0. This means that all safety functions
are selected. STO has in this case the highest priority, i.e. the pulses are safely canceled.
