PARAMETERS
(2) How to use the DY signal (when "1" is set in Pr. 305)
Digital signal input
(terminal X0 to X15)
Data read timing signal
(terminal DY)
REMARKS
• When Pr. 305 = "1", each terminal from X0 to X15 is all recognized as off when the inverter is turned on in terminal
DY off status.
For example, when bias is set to 20Hz, turning the power supply on in the DY signal off status and then turning on
the start signal will make the frequency command valid, starting the inverter to operate at 20Hz.

The setting of "10" for Pr. 305 can be used for the FR-A700/E700 series and FR-F700 series produced in
June 2004 or later. Check the SERIAL number indicated on the inverter rating plate or package.
Refer to the inverter manual for the location of the rating plate.
