Write in Holding Register [06h]:
This function writes data in a specified holding register. An example follows:
• Write "50Hz" as the first Multi-speed 0 (A020) in an inverter having slave address
"5."
• This example uses change data "500(1F4h)" to set "50Hz" as the data resolution of the
register "003Ah" holding the first Multi-speed 0 (A020) is 0.1Hz
