INSTALLATION AND WIRING
2.4.4 Control circuit terminals
indicates that terminal functions can be selected from Pr. 178 to Pr. 196 (I/O terminal function selection) (Refer to the
Instruction Manual (applied).)

Contact input
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.
Input resistance
4.7kΩ
Voltage at
opening: 21 to
27VDC
Contacts at
short-circuited: 4
to 6mADC
43
STR
Reverse
rotation start
Turn on the STR signal to start reverse
rotation and turn it off to stop.
STOP
Start self-
holding
selection
Turn on the STOP signal to self-hold the start signal.

RH,
RM, RL
Multi-speed
selection
Multi-speed can be selected according to the combination of
RH, RM and RL signals.
45
JOG
Jog mode
selection
Turn on the JOG signal to select Jog operation (initial setting)
and turn on the start signal (STF or STR) to start Jog
operation.
Instruction
Manual
(applied)
RT
Second
acceleration/
deceleration
time
selection
Turn on the RT signal to select second acceleration/
deceleration time.
When the second function such as "second torque boost" and
"second V/F (base frequency)" are set, turning on the RT
signal selects these functions.
Instruction
Manual
(applied)
MRS Output stop
Turn on the MRS signal (20ms or more) to stop the inverter
output.
Use to shut off the inverter output when stopping the motor by
electromagnetic brake.
Instruction
Manual
(applied)
RES Reset
Used to reset alarm output provided when protective function
is activated.
Turn on the RES signal for more than 0.1s, then turn it off.
Initial setting is for reset always. By setting Pr.75, reset can be
set to enabled only at an inverter alarm occurrence. Recover
about 1s after reset is cancelled.
74
AU
Terminal 4
input selection
Terminal 4 is made valid only when the AU signal is turned on. (The
frequency setting signal can be set between 4 and 20mADC.)
Turning the AU signal on makes terminal 2 (voltage input) invalid.
49
PTC input
AU terminal is used as PTC input terminal (thermal protection
of the motor). When using it as PTC input terminal, set the AU/
PTC switch to PTC.
Instruction
Manual
(applied)
CS
Selection of
automatic
restart after
instantaneous
power failure
When the CS signal is left on, the inverter restarts automatically at
power restoration. Note that restart setting is necessary for this
operation. In the initial setting, a restart is disabled.
(Refer to Pr.57 Restart coasting time in Instruction Manual (applied).)

Contact input
common
(sink)
Common terminal for contact input terminal (sink logic) and
terminal FM.
Common output terminal for 24VDC 0.1A power supply (PC
terminal).
Isolated from terminals 5 and SE.

(source)
When connecting the transistor output (open collector output),
such as a programmable controller (PLC), when sink logic is
selected, connect the external power supply common for
transistor output to this terminal to prevent a malfunction caused
by undesirable currents.
Can be used as 24VDC 0.1A power supply.
When source logic has been selected, this terminal serves as
a contact input common.
