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.
 You can set this parameter during operation.

COM1 Transmission Speed
Default: 9.6
Settings
4.8–115.2 Kbps
 Sets 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

COM1 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
 Determines 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.
 When a transmission error occurs (for example, the error code CE10 displays), the error remains
even if the transmission status returns to normal, and is not cleared automatically. In this case,
set a reset command (Reset) to clear the error.
