location
symbol
Digital signal input terminal (frequency setting signal terminal).
Input the digital signal at the relay contact or open collector terminal.
(Refer to
X0 to X15
For the digital signal input, choose either BCD code or binary.
BCD code input is 3-digit (999 maximum) or 4-digit (9999 maximum).
Binary input is 12-bit (X0 to X11, HFFF maximum) or 16-bit (X0 to X15,
Built-in
HFFFF maximum).
options
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 while the DY
DY
signal is ON.
In addition, the X0 to X15 data before the signal is turned OFF is retained
by turning OFF the DY signal. (Refer to
Common terminal (sink).
SD
Common terminal for digital and data read timing signals.
Use terminal SD of the inverter.
External transistor common (sink), common terminal (source).
Inverter
Connect this terminal to the external power supply common terminal (+) of
a transistor output (open collector output) device, such as a programmable
PC
controller, to avoid malfunction by undesirable current. When the source
logic is selected, this terminal is used as a common terminal. Use terminal
PC of the inverter.
