Check the auxiliary code (format XYY).An analog signal is outside the limits
specified for the analog input.
AI Supervised
Warning
A8A0
“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 3.
Check the source of the warning
(parameter 32.7 Supervision 1 signal).
Warning generated by the signal
supervision 1 function.
Signal
supervision
A8B0
Check the source of the warning
(parameter 32.17 Supervision 2 signal).
Warning generated by the signal
supervision 2 function.
Signal
supervision 2
A8B1
Check the source of the warning
(parameter 32.27 Supervision 3 signal).
Warning generated by the signal
supervision 3 function.
Signal
supervision 3
A8B2
Check for any operating conditions
increasing the monitored signal (for
Selected signal has exceeded the user
overload curve.
ULC overloadA8BE
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 curve).
Check for any operating conditions
decreasing the monitored signal (for
Selected signal has fallen below the
user underload curve.
ULC
underload
A8BF
example, loss of load if the torque or
current is being monitored).
Check the definition of the load curve
(parameter group 37 User load curve).
