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.
