Writes data to the specified holding register.
Example
To write 50 Hz to the inverter with slave address as the 1st Base Frequency value.
Because the holding register 2F4E hex for the Multispeed-0 setting, 1st-motor (Ab110) has a data reso-
lution of 0.01 Hz, to set 50 Hz, set the written data to 5000 (1388 hex).
Query
Response
Note that, except for FA-01, changing the parameter value on the data display does not update the dis-
played data realtime.
To view the updated value, once return to the parameter display and then display the data again.
If the Write to Holding Register function is executed normally, refer to Exception Response on page
