Input Terminals; Run (Start) And Stop (Stf, Str, Stop) - Mitsubishi Electric FR-V560 Instruction Manual

1.10 Input terminals

1.10.1 Run (start) and stop (STF, STR, STOP)

To start and stop the motor, first switch on the input power of the inverter (when there is a magnetic contactor on the
input side, use the operation-ready switch to turn on the magnetic contactor), then start the motor with the forward
or reverse rotation start signal.
(1) Two-wire type (STF, STR)
A two-wire type connection is shown on the right.
1) The forward/reverse rotation signal is used as both
the start and stop signals. Turn on either of the for-
ward and reverse rotation signals to start the motor
in the corresponding direction. Turn on both or turn
off the start signal during operation to decelerate the
inverter to a stop.
2) The speed setting signal may either be given by
entering 0 to 10VDC across the speed setting input
terminal 2-5 or by setting the required values in Pr. 4
to Pr. 6 "three-speed setting" (high, middle, low
speeds). (Refer to page 90 for three-speed opera-
tion.)
(2) Three-wire type (STF, STR, STOP)
A three-wire type connection is shown on the right. Assign
the start self-holding signal (STOP) to any of the input
terminals.
1) Short signals STOP-SD to enable the start self-holding
function. In this case, the forward/reverse rotation sig-
nal functions only as a start signal.
REMARKS
Assign the STOP signal to any of Pr. 180 to Pr. 183 and
Pr. 187 (input terminal function selection).
2) If the start signal terminals STF (STR)-SD are once
shorted, then opened, the start signal is kept on and
starts the inverter. To change the rotation direction,
short the start signal STR (STF)-SD once, then open it.
3) The inverter is decelerated to a stop by opening termi-
nals STOP-SD once. The three-wire connection is
shown on the right.
4) When terminals JOG-SD are shorted, the STOP signal
is invalid and jog signal has precedence.
5) If the output stop terminals MRS-SD are shorted, the
self-holding function is not deactivated.
