Converter mode: n-00 and Converter model: n-01
By reading out these settings, you can check the converter mode and model.
This parameter is for read-out only. You cannot use it for writing. Writing is always prohibited.
When changing the converter model specified for the control board <VFC66R-Z> due to replacement of spare parts,
etc., you should first initialize memory.
For how to initialize memory, refer to {8.3. How to Initialize Converter Main Unit}.
PWM carrier frequency: n-02
This indicates a PWM carrier frequency. Normally, do not change the initial value.
For special adjustment: n-03 and n-04
Do not set these parameters since they are provided for special adjustment.
