Initiating a protective function
A fault (protective function) is initiated by setting the parameter.
This function can be used to check how the system operates at activation of a protective function.
• To initiate a fault (protective function), set the assigned number of the protective function to be initiated in
Pr.997
.
• The value set in
Pr.997
is not stored in EEPROM.
• When the protective function is activated, the inverter output is shut off and the inverter displays the fault indication and
outputs a Fault (ALM) signal.
• The latest fault in the fault history is displayed while the fault initiation function is in operation. After a reset, the fault history
goes back to the previous status. (The protective function generated by the fault is not saved in the fault history.)
• Perform inverter reset to cancel the protective function.
• For the selectable parameter by
Pr.997
and the corresponding protective functions, refer to the Instruction Manual
(Maintenance).
NOTE
• If a protective function is already operating, no fault can be activated by
Pr.997
.
• The retry function is disabled when a protective function has been initiated by the fault initiation function.
• If a fault occurs after a protective function has been activated, the protective function indication does not change. The fault is
not saved in the fault history either.

Fault initiation
9999
16 to 253
The setting range is the same with the one for fault data codes of the
inverter (which can be read through communication). Written data is not
stored in EEPROM.
9999
The read value is always "9999". The protective function is not
activated with this setting.
