90 EM-ABS-01 for ACU 03/12
8.1.6 Error and warning behavior
he monitorin
of the analo
input si
nal necessary accordin
to the application is
configured via the parameter
Error/Warning Behavior 563 .
Error/warning behavior 563
Function
0 - Off The input signal is not monitored.
1 - Warning < 1V/2mA
If the input signal is lower than 1 V, a warning
message is issued.
2 - Shut Down < 1V/2mA
If the input signal is lower than 1 V, a warning
message is issued; the drive is decelerated ac-
cording to stopping behavior 1.
3 -
Error switch-off
< 1V/2mA
If the input signal is smaller than 1 V, there is a
warning and fault message and the drive mechan-
ism stops freely.
Monitoring of the analo
input si
nal is active re
ardless of the release of the
fre-quency inverter according to the operation mode selected.
In operation mode 2, the drive mechanism is decelerated according to stopping beha-
vior 1 (stop and shutdown) regardless of the stoppin
behavior selected (Paramete
Operation mode 630). If the set holdin
time has expired, an error messa
e is issued.
Repeat startin
of the drive mechanism is possible by switchin
the start si
nal on and
off if the error has already been corrected.
Operation mode 3 defines free coasting of the drive, regardless of the stopping beha-
vior selected defined in parameter
Stopping behavior 630.
Attention!
The monitoring of the analog input signal via parameter
rror/Warnin
behavior
563 demands examination of the characteristic parameters.
