4-2 Function Mode Refer to " " (4-89) if the holding register content reading command has not been performed normally. Writes into one coil. The coil status change is shown in the following table. 4 (Example) •Issues the RUN command to the Inverter with the slave address "8". For running, "03" must be set to "A002". •The coil number of the RUN command is "1". Query Response Functions No. Field name Example (Hex) No.

There is no response for broadcasting. *2. Note that the coil start address is "0", which is smaller by 1 than the coil number "1". The coil addresses for coil numbers from "1 to 31" are "0 to 30". Refer to " " (4-89) if writing into the coil cannot be performed normally.
Writes data into the specified holding register. (Example) Write "50 Hz" into the Inverter with slave address "8" as multi-step speed reference 0 (A020). The data resolution of the holding register "1029h" of multi-step speed reference 0 (A020) is 0.1 Hz. To set 50 Hz, set the change data to "500 (01F4h)". 4-86 Data Coil status OFF → ON ON → OFF Change data (MSB) FFh 00h Change data (LSB) 00h 00h
