Pr.991 PU contrast adjustment
Contrast adjustment of the LCD of the parameter unit (FR-PU04/
FR-PU07) can be performed.
Decreasing the setting value makes the contrast lighter.

Initiating a fault
Pr.997 Fault initiation
A fault is initiated by setting the parameter.
This function is useful to check how the system operates at a fault.
The read value is always "9999." Setting "9999" does not initiate a
fault.

Pr.999 Automatic parameter setting
Parameter settings are changed as a batch. Those include
communication parameter settings for the Mitsubishi human
machine interface (GOT) connection, rated frequency settings
of 50Hz/60Hz.
Multiple parameters are changed automatically. Users do not
have to consider each parameter number. (Parameter setting
