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.

Description
Fault/Alarm range intended for the
user's application developed in the
SoftPLC function.
Faults and Alarms for PID Controller Application (P903 = 1)
Description
It indicates that the PID Controller is in
the sleep mode.
It indicates that the level of the control
process variable (P916) is low.
It indicates the motor was switched
off due to the low level of the control
process variable.
It indicates that the level of the control
process variable (P916) is high.
It indicates the motor was switched
off due to the high level of the control
process variable.
It indicates that parameters of the
speed reference sources in local mode
(P221) and in remote mode (P222) were
not programmed for the SoftPLC.
Possible Causes
Defined by the user's application developed in the SoftPLC
function.
Possible Causes
The motor speed remained below the value programmed in
P938 for the time programmed in P939.
The control process variable (P916) remained below the
value programmed in P924 for 150 ms.
The control process variable (P916) remained below the
value programmed in P924 for a certain time (P925).
The control process variable (P916) remained above the
value programmed in P926 for 150 ms.
The control process variable (P916) remained above the
value programmed in P926 for a certain time (P927).
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).
