11.1.1 Handling the -STOEM Fault Marker
Symbol CL200 CL400/CL500
-STOEM M191.2 M255.2
The -STOEM fault marker makes it possible to provide fault indications
independent of the monitoring time. This may comprise the detection of
an exceeded temperature regulation threshold value, or simply an excess
RPM.
NOTE! The fault marker is influenced only by the user.
In the fault-free system condition, the -STOEM fault marker is logical 1
bin
.
It is reset in the event that a fault must be indicated.
Example:
; Step conditions
; Step 1
-S1
; Conditions for Automatic and/or Inching mode
;Fault marker programming
CPLA W -GRENZW,A ;Threshold value exceeded ?
A B SM31.0 ;arithmetical A > threshold

STOEM
;Diagnostics are triggered
; Links for Automatic and Inching Mode
-AUTO
A B I0.6
= B -BEFA
A B I0.7
= B -WSB ; Compulsory requirement
EM ; for end of step.
Further cascade processing depends upon d7.7 of the associated cas-
cade data module:
• D7.7 = 0
bin
Subsequent to correction of the fault,
or when WSB step-on condition is met,
the cascade will start automatically.
OR
• D7.7 = 1
bin
The cascade starts only subsequent to
acknowledgement via D6.6.
