Initiating A Fault (Pr.997) - Mitsubishi F700 Series Instruction Manual

Useful functions

4.22.6 Initiating a fault (Pr.997)

A fault is initiated by setting the parameter.
This function is useful to check how the system operates at a fault.

number
997 Fault initiation
The above parameters can be set when Pr. 160 User group read selection = "0". (Refer to page 185)
(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.

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.

Description
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.
The read value is always "9999."
This setting does not initiate a fault.
