4.22.6 Initiating a fault (Pr.997)
.... The specification differ according to the manufacture date. Refer to page 400 and check the SERIAL.
The above parameters can be set when Pr. 160 User group read selection = "0". (Refer to page 190)
(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 displayed and output (ALM, ALM2).
⋅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
* Refer to the FR-F700 PLC function programming manual for details of the PLC function.
A fault is initiated by setting the parameter.
This function is useful to check how the system operates at a fault.

Fault initiation 9999
16 to 18, 32 to 34, 48, 49,
64, 80 to 82, 96, 112, 128,
129, 144, 145, 160, 161,

196 to 199, 228 to 230,
241, 242, 245 to 247, 253
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.
When "0" is set, nothing happens.
9999
The read value is always "9999."
This setting does not initiate a fault.
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.
