2.3 Control circuit specifications
2.3.1 Control circuit terminal
indicates that terminal functions can be selected using Pr. 178 to Pr. 184, Pr. 190 to Pr. 192 (I/O terminal function
selection) . (Refer to page 139) .

Cont
act
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 4.7k
Ω
Voltage when contacts are
open
21 to 26VDC
When contacts are short-
circuited
4 to 6mADC
143
STR Reverse rotation start
Turn ON the STR signal to
start reverse rotation and
turn it OFF to stop.
RH,
RM,
RL
Multi-speed selection
Multi-speed can be selected according to the
combination of RH, RM and RL signals.
102
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.
* Terminal MRS is only available for the standard control
circuit terminal model.
141
RES Reset
Used to reset fault output provided when fault occurs.
Turn ON the RES signal for more than 0.1s, then turn
it OFF.
Factory setting is for reset always. By setting
Pr. 75 ,
reset can be set to enabled only at fault occurrence.
Recover about 1s after reset is cancelled.
184
SD
Contact input common
(sink) (initial setting) Common terminal for contact input terminal (sink
logic) and terminal FM.

External transistor
common (source)
When connecting the transistor output (open collector
output), such as a programmable controller, when
source logic is selected, connect the external power
supply common for transistor output to this terminal to
prevent a malfunction caused 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)
When connecting the transistor output (open collector
output), such as a programmable controller, 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.
Power supply voltage range
22 to 26.5VDC
permissible load current
100mA
25
Contact input common
(source) Common terminal for contact input terminal (source
logic).
24VDC power supply Can be used as 24VDC 0.1A power supply.
Safety stop input terminal
common *
Common terminal for safety stop input terminals S1
and S2.
* Terminal S1 and S2 are only available for the safety
stop function model.
