STF
*1
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: 4.7 k Ω ,
voltage when contacts
are open: 21 to 26 VDC,
current when contacts are
short-circuited: 4 to 6
mADC

STR
*1
Reverse rotation start
Turn ON the STR signal to start
reverse rotation and turn it OFF to
stop.
RH
RM
RL
*1
Multi-speed selection
Multi-speed can be selected according to the combination of
RH, RM and RL signals.
*2
MRS
*1
Output stop
Turn ON the MRS signal (20 ms or more) to stop the inverter
output. Use this signal to shut off the inverter output when
stopping the motor with an electromagnetic brake.
*2
RES
*1
Reset
Use this signal to reset a fault output provided when a
protective function is activated. Turn ON the RES signal for
0.1 seconds or longer, then turn it OFF.
In the initial setting, reset is always enabled. By setting
Pr.75 , reset can be enabled only at an inverter fault
occurrence. The inverter recovers about 1 second after the
reset is released.

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.
24 VDC power supply
common
Common terminal for the 24 VDC power supply (terminal
PC).
Isolated from terminals 5 and SE.

External transistor
common (sink)
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.

Safety stop input
terminal common
Common terminal for safety stop input terminals
Contact input
common (source)
Common terminal for contact input terminal (source logic).
24 VDC power supply Can be used as a 24 VDC 0.1 A power supply.
