PARAMETERS
4.18.5 Free parameter (Pr. 888, Pr. 889)
4.18.6 Initiating a fault (Pr. 997)
The above parameters can be set when Pr. 160 Extended function display selection = "0". (Refer to page 144)
(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 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
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
Name Initial Value Setting Range Description
888 Free parameter 1
9999 0 to 9999
Any values can be set. Data is held even
if the drive unit power is turned OFF.
889 Free parameter 2
9999 0 to 9999
The above parameters can be set when Pr. 160 Extended function display selection = "0". (Refer to page 144)
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.
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,

192, 196, 197, 199, 201,
208, 230, 245
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.
9999
The read value is always "9999."
This setting does not initiate a fault.
