Input the digital signal at the relay contact or open collector terminal.
Using Pr. 360 , speed or position command is selected as the command signal
entered.
Used when a digital signal read timing signal is necessary. Data is read only
during the DY signal is on.
By switching the DY signal off, the X0 to X15 data before signal-off can be
retained.
Common terminal for digital and data read timing signals.
Use terminal SD of the inverter.
When connecting the transistor output (open collector output), such as a
programmable controller, connect the external power common (+) to this
terminal to prevent a fault occurring due to leakage current.
