4.22.6 Initiating a fault (Pr.997)
(1)
Fault initiation (Pr. 997)
To initiate a fault, set the assigned number of the fault you want to initiate in
Pr. 997 Fault initiation
.
The value set in
Pr. 997 Fault initiation
is not stored in EEPROM.
When a fault occurs, the inverter trips, and the fault is output (ALM).
While the initiated fault is occurring, the fault is displayed as the latest fault in the faults history. After a reset, the faults
history goes back to the previous status. (The fault generated by the fault initiation function is not saved in the faults
history.)
Perform inverter reset to cancel the fault.
Setting for
Pr. 997 Fault initiation
and corresponding faults
A fault is initiated by setting the parameter.
This function is useful to check how the system operates at a fault.

16 to 18, 32 to 34, 48, 49,
64, 81, 82, 96, 97, 112,

201, 208, 230, 245
The setting range is same with the one for
fault data codes of the inverter (which can
be read through communication).
Written data is not stored in EEPROM.
9999
The read value is always "9999."
This setting does not initiate a fault.
The above parameters can be set when User group read selection=
"0".
.... Specifications differ according to the date assembled.
to check the SERIAL number.
REMARKS
If a fault is already occurring in the inverter, a fault cannot be initiated by
Pr. 997
.
The retry function is invalid for the fault initiated by the fault initiation function.
If another fault occurs after a fault has been initiated, the fault indication does not change.
The fault is not saved in the faults history either.
