09 Communication Parameters
When using the communication interface, the
diagram on the right shows the communication port
pin definitions. We recommend that you connect the
AC motor drive to your PC by using Delta IFD6530
orIFD6500 as a communication converter.
For more details, refer to Appendix A. Modbus
Protocol.
You can set this parameter during the operation.

Modbus Slave Communication Address
Default: 1
Settings 1–254
Set the communication address for the drive if the AC motor drive is controlled through RS-485
serial communication. The communication address for each AC motor drive must be unique.
09-01
COM1 Modbus Transmission Speed
Default: 9.6
Settings 4.8–115.2 Kbps
Set the transmission speed between the computer and the AC motor drive.
Options are 4.8 Kbps, 9.6 Kbps, 19.2 Kbps, 38.4 Kbps, 57.6 Kbps, or 115.2 Kbps; otherwise, the
transmission speed is set to the default 9.6 Kbps.

COM1 Modbus Transmission Fault Treatment
Default: 3
Settings 0: Warn and continue operation
1: Fault and ramp to stop
2: Fault and coast to stop
3: No warning, no fault and continue operation
Determine the treatment when an error is detected that the host controller does not continuously
transmit data to the AC motor drive during Modbus communication. The detection time is based
on the Pr.09-03 setting.
09-03
COM1 Modbus Time-Out Detection
Default: 0.0
Settings 0.0–100.0 sec.
Set the communication time-out value.
