EIA-485 embedded fieldbus connection
You can connect the drive to a serial communication link with a fieldbus adapter module or the embedded fieldbus
interface. The embedded fieldbus interface supports Modbus RTU.
To configure Modbus RTU communication with the embedded fieldbus:
1.
Connect the fieldbus cable and the required I/O signals. Use Belden 9842 or equivalent. Belden 9842 is a dual twisted,
shielded pair cable with a wave impedance of 120 Ohms.
2.
If the drive is at the end of the fieldbus, set the termination switch to ON.
3.
Power up the drive and set the required parameters. Refer to
