8-9 Modbus Communication Data Lists
R/W in the list shows whether data can be read from, or written to, the coil or holding register.
(R: Read only, R/W: Read and write enabled)
Precautions for Correct Use
• The “Coil No.” in the table header shows the coil number used inside the inverter.
Use this coil number when setting EtherCAT communications.
• The “Modbus coil spec. No.” in the table header shows the coil number used to actually spec-
ify the coil in the Modbus communication process.
This coil number is 1 less than the inverter “Coil No.” according to the Modbus communica-
tion specifications.
