Free Parameter (Pr. 888, Pr. 889); Initiating A Fault (Pr. 997) - Mitsubishi Electric FR-D720-0.2K-G Instruction Manual

Useful functions

4.19.5 Free parameter (Pr. 888, Pr. 889)

You can input any number within the setting range of 0 to 9999.
For example, the number can be used:
 As a unit number when multiple units are used.
 As a pattern number for each operation application when multiple units are used.
 As the year and month of introduction or inspection.
Parameter
Number
888 Free parameter 1
889 Free parameter 2
The above parameters can be set when Pr. 160 Extended function display selection = "0". (Refer to page 161.)
The above parameters allow their settings to be changed during operation in any operation mode even if "0" (initial value) is set in Pr. 77 Parameter
write selection.
REMARKS
Pr. 888 and Pr. 889 do not influence the drive unit operation.

4.19.6 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.

997 Fault initiation
The above parameters can be set when Pr. 160 Extended function display selection = "0". (Refer to page 161.)
(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 output (ALM).
 While the initiated fault is occurring, the fault is displayed as the latest fault in the fault history. After a reset, the fault
history goes back to the previous status. (The fault generated by the fault initiation function is not saved in the fault
history.)
 Perform drive unit reset to cancel the fault.

Description
Any values can be set. Data is held even
if the drive unit power is turned OFF.
Description
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.
The read value is always "9999."
This setting does not initiate a fault.
