4.18.7 Batch setting Mitsubishi HMI (GOT) connection parameters (Pr. 999)
∗ The read value is always "9999."
(1) Automatic parameter setting (Pr. 999)
Setting Pr. 999 = "10" will automatically set the communication parameters required to connect a GOT to the PU
connector.
To operate in the parameter setting mode, go to "AUTO" → "GOT", then write "1".
The following tables show which parameters are changed in each of the automatic parameter settings.
GOT initial setting (PU connector) (Pr. 999 = “10”)
REMARKS
If a fault is already occurring in the drive unit, 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.
Communication parameters for the Mitsubishi HMI (GOT) connection can be set as a batch.
Multiple parameters are changed automatically. Users do not have to consider each parameter number. (Parameter
setting mode)

NOTE
y If the automatic setting is performed with Pr. 999 or the parameter setting mode, the listed settings including the changed
parameter settings (changed from the initial setting) will be automatically changed. Before performing the automatic setting,
confirm that changing the listed parameters will not cause any problem.
