âš« 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 or IFD6500 as a communication
converter. Refer to the RJ45 terminal on Section 3-4-1
Wiring for details of the communication port on the right.
âš« Default communication format of the port:
1. Modbus ASCII mode
2. 9600 bps transmission speed
3. 7 data bits
4. No calibration (NONE)
5. 2 stop bits
âš« Modbus ASCII (American Standard Code for Information Interchange): Each byte of data is
the combination of two ASCII characters. For example, one byte of data: 64 Hex, shown as
‘64’ in ASCII, consists of ‘6’ (36Hex) and ‘4’ (34Hex).
