Communication setting
(Underlined setting: default)
AC Power Regulator
The communication parameter can be set using keys attached to the front of the AC power regulator.
Be sure to match the settings to those made under [Communication Setting] of the editor.
(Underlined setting: default)
*1 For communication with V9, select “Network device” for the setting device selection and “MODBUS RTU” for the communication protocol
selection on this regulator.
*2 The communication parameter (data length) is fixed to 8 bits.
Available Device Memory
The available setting range of device memory varies depending on the model. Be sure to set within the range available for the
model to be used. Use [TYPE] when assigning indirect device memory for macro programs.
Indirect Device Memory Designation
 For word designation, specify the device memory No. (address) in even address.
Example: To make the setting of “output setting” for the function code 1.b01;
Specify “2” in the device memory No. (address).

For bit designation, it is possible to specify the device memory No. (address) in both even and odd address.
Specify “00H” for the extensional code because the setting range for the bit address is 0 to 7.
Example: To make the setting of “gradient setting selection” for the function code 1.b09;
Specify “1” in the device memory No. (address), “00H” for the extensional code, and “00” or “01” in the bit No..
