Basic Functions
STOP E: NOT POSSIBLE → SS1 immedi-
•
ately responds with STOP B
STOP F (defect in a monitoring channel +
•
programmed subsequent response with
STOP B → STOP A)
ESR integrated in the drive (p0890, ...), is
•
not enabled when using the external ESR.
ESR is requested via r9734.14.
•
The motion control evaluates r9734.14
•
(SIC).
Bit r9734.14 is used as trigger for the ex-
•
ternal CPU, to initiate the external ESR.
The external CPU then specifies the set-
point.

Extended/Advanced Functions
STOP E (internal response to a limit value
•
violation + SLS, SDI, SLP, SLA with sub-
sequent response)
SS2ESR: STOP E explicitly requested by
•
control unit; S_STW2.29 and
S_ZSW3B.12
ESR integrated in the drive (p0890, ...), is
•
not enabled when using the external ESR.
ESR is requested via r9734.14.
•
The motion control evaluates r9734.14
•
(SIC).
Bit r9734.14 is used as trigger for the
•
external CPU, to initiate the external ESR.
In addition, bit r10234.12 (S_ZSW3B) is
set if the request was received via
S_STW2.29. This allows a distinction to
be made between cases where ESR was
triggered by a limit value being violated.
The external CPU then specifies the set-
point.
STOP F (defect in a monitoring channel +
•
programmed subsequent response with
STOP B → STOP A)
You can request an ESR in the time from
•
STOP F to STOP B.
ESR integrated in the drive (p0890, ...), is
•
not enabled when using the external ESR.
ESR is requested via r9734.14.
•
The motion control evaluates r9734.14
•
(SIC).
Bit r9734.14 is used as trigger for the
•
external CPU, to initiate the external ESR.
The external CPU then specifies the set-
point.
