STF Forward rotation start
Turn ON the STF signal to start
forward rotation and turn it OFF
to stop.
When the STF and STR
signals are turned ON
simultaneously, the stop
command is given.

Multi-speed selection
Multi-speed can be selected according to the combination
of RH and RM signals.

AU Terminal 4 input selection
The terminal 4 function is available only when the AU
signal is ON. (The operation with the frequency setting
signal of 4 to 20mA DC is available)

External transistor
common (source)
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.
24VDC power supply

Common output terminal for 24VDC 0.1A power supply
(PC terminal).
Isolated from terminals 5 and SE.

Frequency setting
(voltage)
Inputting 0 to 5VDC (or 0 to 10V) provides the maximum
output frequency at 5V (10V) and makes input and output
proportional. Use
Pr. 73
to switch between input 0 to 5VDC
input (initial setting) and 0 to 10VDC.

Frequency setting
(current)
Inputting 4 to 20mADC (or 0 to 5V, 0 to 10V) provides the
maximum output frequency at 20mA and makes input and
output proportional. The input signal to terminal 4 is valid
only when the AU signal is ON (terminal 2 input is invalid).
Use
Pr. 267 to switch from
among input 4 to 20mA (initial
setting), 0 to 5VDC and 0 to
10VDC. Set the voltage/
current input switch in the "V"
position to select voltage
input (0 to 5V/0 to 10V).

NOTE
Set Pr. 267 and a voltage/current input switch correctly, then input analog signals in accordance with the settings.
Applying a voltage with voltage/current input switch in "I" position (current input is selected) or a current with switch in
"V" position (voltage input is selected) could cause component damage of the inverter or analog circuit of output
devices.
