Digital signal input terminal (frequency setting signal terminal)
Input the digital signal at the relay contact or open collector
terminal. (Refer to page 12.)
For the digital signal input, you can choose either the BCD code
X0 to X15
input or binary input.
BCD code input.... 3-digit (999 maximum) or 4-digit (9999
Plug-in
Binary input .......... binary 12-bit (X0 to X11, FFF
option
Data read timing input signal
Use when a digital signal read timing signal is necessary. When
Pr. 305 Read timing operation selection ="1", data is read only
DY
during the DY signal is on. In addition, the X0 to X15 data before
signal-off is retained by switching the DY signal off. (Refer to page
19.)
Common terminal (sink)
SD
Common terminal for digital and data read timing signals.
Use terminal SD of the inverter.
External transistor common terminal (sink), common terminal (source)
When connecting the transistor output (open collector output) of
Inverter
a programmable controller, etc., connect the external power
PC
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. Use terminal PC of the
inverter.
