12-BIT DIGITAL INPUT
3.2 Terminals
Terminal Symbol Description
X0 to X11
Digital signal input terminals (frequency/speed setting signal terminals)
Used to input a 3-digit BCD (999 maximum) (refer to page 6) or 12-bit binary (FFFH maxi-
mum) relay contact or open collector signal.
DY
Data read timing input signal
Used when a digital signal read timing signal is necessary.
Data is only read while the DY signal is on.
By switching the DY signal off, the X0 to X11 data before signal-off is retained. (Refer to page
12.)
SD
Common terminal (sink)
Common terminal for digital and data read timing signals.
This terminal is the SD terminal of the inverter.
PC
External transistor common terminal (source)
When connecting the transistor output (open collector output) of a programmable controller
(PC), etc., connect the external power common (+) to this terminal to prevent a fault occurring
due to leakage current. When you have selected the source logic, this terminal is used as a
common terminal. This terminal is the PC terminal of the inverter.
