Description
Turn ON the STF signal to
start forward rotation and
turn it OFF to stop.
Turn ON the STR signal to
start reverse rotation and
turn it OFF to stop.
Multi-speed can be selected according to the
combination of RH, RM and RL signals.
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.
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.
Common terminal for contact input terminal (sink logic)
and terminal FM.
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.
Common output terminal for 24VDC 0.1A power
supply (PC terminal).
Isolated from terminals 5 and SE.
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.
Common terminal for contact input terminal (source
logic).
Can be used as 24VDC 0.1A power supply.
Rated Specifications
When the STF and STR
signals are turned ON
simultaneously, the stop
command is given.
Input resistance 4.7kΩ
Voltage when contacts are
open
21 to 26VDC
When contacts are short-
circuited
4 to 6mADC
Power supply voltage range
22 to 26.5VDC
permissible load current
