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.
Turn on the STOP signal to self-hold the start signal.
Multi-speed can be selected according to the combination of
RH, RM and RL signals.
Turn on the JOG signal to select Jog operation (initial setting)
and turn on the start signal to start Jog operation.
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.
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 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.
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.
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.
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).)
Common terminal for contact input terminal and terminal CA
for sink logic.
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 (PLC), 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
NO contact input common.
Specifications
When the STF and
STR signals are turned
on simultaneously, the
stop command is given.
