External fault setting
The inverter acts as a Modbus master
ICON500 can be used as a Modbus master station, it currently only supports broadcast network.
When P30.09 is set as 1, master mode can be enabled. The sending frame as master station is as
follows:
0x00
0x06
0x70
N
ValH
ValL
CRCL
CRCH
Instruction
:
1. N indicates the slave register of the operation which is set by P30.10.
2. Val means the data sent, Val = (ValH << 8) + ValL, the function code P30.11 is to select the
contents of the data sent.
3. The idle time between frame and frame is set by function code P30.12.
