HMI – VFD Communication Example

In a near future we are going to post several communication examples between Delta HMI touch pannels and the different Delta devices.
Today we start on one of the most demanded:
Delta HMI with Delta Inverter.

The example is programmed with Screen Editor 2.00.20

Protocol used:
7,N,2 (Modbus, ASCII), 9600 bps

Network configuration:
HMI Address: 0 (master)
VFD Address: 1 (Slave)

VFD Configuration:
2.00 = 3 (frequency source RS485 communication)
2.01 = 3 (Operation command source RS485 communication)
9.00 = 1 (Station Address)
9.01 = 1 (9600 bps)
9.04 = 0 (7,N,2, Modbus, ASCII)
