Rating, etc. Application Explanation
Turning ON STF signal gives forward
F700
command and off gives stop
command.
D700
Turning ON STR signal gives reverse
command and off gives stop
command.
Turning ON STF and STR signals
simultaneously gives stop command.
Turning ON STOP signal selects the
self-hodling start method.
If the start signal STF (STR) is once
turned ON, the start signal is held
and the inverter continues running.
To stop the motor, turn OFF terminal
STOP. To change the rotation
direction, turn ON, then OFF the start
signal STR (STF).
The self-holding start method
prevents the inverter from
automatically restarting when power
is restored after a power failure.
Turn ON RH signal to perform
operation at the frequency set in [Pr.
4]. Turn ON RM signal to perform
operation at the frequency set in [Pr.
5] or turn ON RL signal to perform
operation at the frequency set in [Pr.
6].
When any two or more terminals of
RH, RM and RL are turned ON at the
F700
same time, priority is given to the
lower-speed signal. Three speeds
D700
selection has higher priority than the
analog frequency setting signal.
For multi-speed selection, setting
multi-speed frequencies in [Pr. 24 to
Pr. 27, Pr. 232 to Pr. 239] allows up to
15 speeds to be selected by the
combinations of RH, RM, RL, REX
signal. Allocate REX signal to any of
the terminals using input terminal
function selection.
Multi-speed selection has higher
priority than the analog frequency
setting signal.
Turn ON JOG signal and use terminal
STF (STR) signal to run/stop.
JOG terminal can be used as pulse
train input terminal.
To use as pulse train input terminal,
the [Pr. 291] setting needs to be
changed.
When second function such as [Pr.
44, Pr. 45, Pr. 46] is set, turning ON RT
signal selects the second function.
