High-function General-purpose Inverter 3G3RX-V1 User’s Manual (I578-E1)
Writes data to consecutive multiple holding registers.
Example
To write 3,000 seconds to the inverter with slave address 1 as the 1st Acceleration Time 1 (F002) value.
Because the holding registers 1103 hex to 1104 hex for the 1st Acceleration Time 1 (F002) has a data
resolution of 0.01 seconds, to set 3,000 seconds, set the written data to 300000 (493E0 hex).
Query
Response
*1 During a broadcast, no response will be sent back.
*2 Note that the resister start address is 1102 hex, which is 1 less than the register number 1103 hex.
*3 This is not the number of holding registers, but the number of bytes to be changed actually.
If the Write to Holding Register function is not executed normally, refer to the “Exception Response”
section.
