Terminal function description
Turn ON the STF signal to start
forward rotation and turn it OFF to
stop.
Turn ON the STR signal to start
reverse rotation and turn it OFF to
stop.
Common terminal for the contact input terminal (sink logic).
Connect this terminal to the power supply common terminal
of a transistor output (open collector output) device, such as
a programmable controller, in the source logic to avoid
malfunction by undesirable current.
Common terminal for the 24 VDC power supply (terminal
PC). Isolated from terminal 5.
Connect this terminal to the power supply common terminal
of a transistor output (open collector output) device, such as
a programmable controller, in the sink logic to avoid
malfunction by undesirable current.
Common terminal for safety stop input terminals
Common terminal for contact input terminal (source logic).
When connecting the frequency setting potentiometer at an
initial status, connect it to terminal 10.
Inputting 0 to 5 VDC (or 0 to 10 VDC) provides the maximum
output frequency at 5 V (or 10 V) and makes input and
output proportional. Use Pr.73 to switch among input 0 to 5
VDC (initial setting), 0 to 10 VDC, and 0 to 20 mA.
* The initial setting varies depending on the specification.
Set the voltage/current input switch to the "I" position to
select current input (0 to 20 mA).
Inputting 4 to 20 mADC (or 0 to 5 VDC, 0 to 10 VDC)
provides the maximum output frequency at 20 mA and
makes input and output proportional. This input signal is
valid only when the AU signal is ON (terminal 2 input is
invalid).
To use the terminal 4 (current input at initial setting), assign
"4" to Pr.178 or Pr.179 (Input terminal function selection)
before turning ON the AU signal.
* The initial setting varies depending on the specification.
Use Pr.267 to switch among input 4 to 20 mA (initial setting),
0 to 5 VDC, and 0 to 10 VDC. Set the voltage/current input
switch to the "V" position to select voltage input (0 to 5 V / 0
to 10 V).
Common terminal for the frequency setting signal (terminal
2 or 4). Do not earth (ground).
