• The “Register No.” in the table header shows the resister number used inside the inverter.
Use this register number when setting communications or other options for the inverter.
• The “Modbus register spec. No.” in the table header shows the resister number used to
actually specify the resister in the Modbus communication process.
This resister number is 1 less than the inverter “Register No.” according to the Modbus
communication specifications.
