9.11 Extended stop and retract
Triggering for all drives of a Control Unit
Conditions for triggering the function:
● ESR function has been configured in the drive, e.g. stopping or retraction.
● ESR function has been enabled in the drive.
● The pulse enable has been set.
A distinction is made between the following fault sources:
● Communication failure:
– The Control Unit detects the communication failure and triggers autonomous reactions
– A status checkback signal is no longer possible.
– The higher-level control removes the "Master control by PLC" signal (F07220).
– Interruption of data transmission via the fieldbus (F01910 or F08501).
● External trigger signal
– An external trigger signal from the control triggers the ESR function via the telegrams
9.11.3

Invalid trigger sources

The following DRIVE-CLiQ communication failures do not produce an ESR trigger:
Event
Pulse suppression of the Motor Modules is pending
Failure of encoder modules as motor measuring system
Failure of encoder modules as a direct application-specific
measuring system

9.11.4.1

Extended stopping

Overview
In the case of a fault, the objective is to stop the drive in a defined fashion. The stopping method
is used as long as the drive is still capable of functioning. The function is parameterized and
operates on an axis-specific basis. Axes are not coupled.

in all the enabled drives.
390, 391 or 392.
Sequence
The drive performs an OFF2 and coasts to a standstill.
The system is switched over to operation without encoder and
a parameterized stop reaction is initiated.
The application is deactivated and a parameterized stop re‐
action initiated.
