14.1.1.5 Error and warning behavior
For monitoring the analog input signal, an operation mode can be selected via pa-
rameter
Error/warning behavior
453
.
Error/Warning Behavior
453
Function
0 - Off
The input signal is not monitored.
1 - Warning < 1V/2mA
If the input signal is lower than 1 V or 2 mA, a
warning message is issued.
2 - Shut Down < 1V/2mA
If the input signal is lower than 1 V or 2 mA, a
warning message is issued; the drive is deceler-
ated according to stopping behavior 2.
3 -
Error Switch-Off
< 1V/2mA
If the input signal is lower than 1 V or 2 mA, a
warning and fault message is issued and the
drive coasts to a standstill (stopping behavior 0).
Monitoring of the analog input signal is active regardless of the release of the fre-
quency inverter according to the operation mode selected.
Operation mode
2
defines the shut-down and stopping of the drive, regardless of the
setting of parameter
Operation mode
630
for the stopping behavior. The drive is
stopped according to stopping behavior 2. If the set holding time has expired, an error
message is issued. The drive can be started again by switching the start signal on
and off.
Operation mode
3
defines the free coasting of the drive(like described for stopping
behavior 0), regardless of the setting of parameter
Operation mode
630
for the stop-
ping behavior.
Attention!
The monitoring of the analog input signal via the parameter
Er-
ror/Warning behavior
453
demands the examination of the parameter
Characteristic point X1

.
Example:

=
„2 - Stop < 1V/2mA“ or „3 – fault switch-off
< 1V/2mA“. In the factory settings of the parameter

shutting down or
fault switch-off are affected at an output frequency
≠
0 Hz. If shutting down or fault
switch-off are to be affected at an output frequency of 0 Hz, the Point X1 must be
adjusted (e.g. X1=10% /1 V).
