Selected signal has fallen below the
user underload curve.
What to do
Check the auxiliary code. Check the
source of the warning corresponding
to the code:
0: 33.13 On-time 1 source
1: 33.23 On-time 2 source
10: 5.4 Main fan on-time
Check the auxiliary code. Check the
source of the warning corresponding
to the code:
0: 33.13 On-time 1 source
1: 33.23 On-time 2 source
10: 5.4 Main fan on-time
Check the auxiliary code. Check the
source of the warning corresponding
to the code:
0: 33.13 On-time 1 source
1: 33.23 On-time 2 source
10: 5.4 Main fan on-time
Check the auxiliary code (format XYY).
"X" specifies the location of the input
(0: AI on control unit; 1: I/O extension
module 1, etc.), "YY" specifies the input
and limit (01: AI1 under minimum, 02:
AI1 over maximum, 03: AI2 under
minimum, 04: AI2 over maximum).
Check signal level at the analog input.
Check the wiring connected to the
input.
Check the minimum and maximum
limits of the input in parameter group
12 Standard AI, 14 I/O extension
module 1, 15 I/O extension module 2
or 16 I/O extension module
Check the source of the warning
(parameter 32.7 Supervision 1
Check the source of the warning
(parameter 32.17 Supervision 2
Check the source of the warning
(parameter 32.27 Supervision 3
Check for any operating conditions
increasing the monitored signal (for
example, the loading of the motor if
the torque or current is being
monitored).
Check the definition of the load curve
(parameter group 37 User load
Check for any operating conditions
decreasing the monitored signal (for
example, loss of load if the torque or
current is being monitored).
Check the definition of the load curve
