Error And Warning Behavior - BONFIGLIOLI ACTIVE Cube ACU 201-01 Operating Instructions Manual

15.1.1.5 Error and warning behavior

For monitoring the analog input signal, an operation mode can be selected via pa-
rameter
Error/Warning Behavior
0 - Off
1 - Warning < 1V/2mA
2 - Shut Down < 1V/2mA
Error Switch-Off
3 -
< 1V/2mA
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
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
stopping behavior.
WARNING
The monitoring of the analog input signal via the parameter
453 demands the examination of the parameter
Example:
off < 1V/2mA". In the factory settings of the parameter
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).

Function
The input signal is not monitored.
If the input signal is lower than 1 V or 2 mA, a
warning message is issued.
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.
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).
