*2. The default settings when initialize by setting 00/01/03 to "Initialize data selection [b085]".
*4. This parameter is a dummy parameter. User setting is disabled. Carrier frequency in DC braking is shared with
"Carrier frequency [b083]". In addition, if data is written within the data range by Modbus communication, no
error will occur.
