• The “Register No.” in the table header shows the register number used inside the inverter.
• The “Modbus register spec. No.” in the table header shows the register number used to actu-
ally specify the register in the Modbus communication process.
This register number is 1 less than the inverter “Register No.” according to the Modbus com-
munication specifications.
