Communication Function
0003h → 03d → E03 (Cause: Overcurrent)
0004h → 4 (Inverter status: Accelerating)
0000 04D2h → 1234d → 12.34 [Hz]
(Frequency)
001Eh → 30d → 3.0 [A] (Current)
011Ch → 284d → 284 [V] (DC)
Response:
*1. Broadcasting cannot be performed.
*2. Data is transferred by the number of data bytes. In this example, 12 (0Ch) bytes are used since 6
pieces of holding register data are returned.
*3. Note that the holding register start address is "0011h", which is smaller by 1 than the register number
"0012h". The register number less 1 corresponds to the register address.
Writing Into the Coil [05h]
Writes into 1 coil. The following table shows the coil status change.
Example) Issue a RUN command to the Inverter whose slave address is "1".
The RUN command selection must be set to Communication (A002 = 03).
The coil number of the RUN command is "0001".
"d": Decimal
"h": Hexadecimal
