QUICK REFERENCE OF ALARMS AND FAULTS
Faults and Alarms for PID Controller Application (P903 = 1)
Fault / Alarm Description Possible Causes
A750
Sleep Mode Active
It indicates that the PID Controller is in
the sleep mode.
The motor speed remained below the value programmed in
P938 for the time programmed in P939.
A760
Low Level of the Control
Process Variable
It indicates that the level of the control
process variable (P916) is low.
The control process variable (P916) remained below the
value programmed in P924 for 150 ms.
F761
Low Level of the Control
Process Variable
It indicates the motor was switched
off due to the low level of the control
process variable.
The control process variable (P916) remained below the
value programmed in P924 for a certain time (P925).
A762
High Level of the Control
Process Variable
It indicates that the level of the control
process variable (P916) is high.
The control process variable (P916) remained above the
value programmed in P926 for 150 ms.
F763
High Level of the Control
Process Variable
It indicates the motor was switched
off due to the high level of the control
process variable.
The control process variable (P916) remained above the
value programmed in P926 for a certain time (P927).
A790
Speed reference source not
programmed for the SoftPLC
It indicates that parameters of the
speed reference sources in local
mode (P221) and in remote mode
(P222) were not programmed for the
SoftPLC.
The PID Controller was enabled, the Run/Stop command
is active, and neither of the two parameters of the speed
reference source was programmed in 12 (SoftPLC).
Fault and alarm operation:
Faults operate by indicating their occurrence on the HMI, in the frequency inverter status word (P006), in the
present fault parameter (P049) and disabling the motor. They can only be reset with a reset command or de-
energizing the frequency inverter.
Alarms operate by indicating their occurrence on the HMI and in the present alarm parameter (P048). They are
automatically reset when the alarm condition ceases existing.
