4.20.6 Initiating a fault (Pr.997)
The above parameters can be set when Pr.160 Extended function display selection = "0". (Refer to page Refer to page 182)
......Specifications differ according to the date assembled. Refer to page 316 to check the SERIAL number.
(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 drive unit trips, and the fault is displayed and 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 drive unit 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, 82, 96, 97, 112, 128,

221, 241, 245, 246, 247, 253
The setting range is same with the one for
fault data codes of the drive unit (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 drive unit, 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.
