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.

STR
Reverse rotation start
Turn ON the STR signal to
start reverse rotation and
turn it OFF to stop.

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

Common terminal for contact input terminal (sink logic)
and terminal FM.

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
currents.
24VDC power supply
common
Common output terminal for 24VDC 0.1A power
supply (PC terminal).
Isolated from terminals 5 and SE.
PC
External transistor
common (sink)
(initial setting)
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 currents.
Power supply voltage range
22 to 26.5VDC

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.

4
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. This input signal is valid
only when the AU signal is ON (terminal 2 input is
invalid). To use terminal 4 (initial setting is current
input), set "4" in any of
Pr.178 to Pr.182 (input terminal
function selection)
to assign the function, and turn ON
AU signal.
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).
