6.10.4 Start signal selection (Terminal STF, STR, STOP, Pr. 250)
You can select the operation of the start signal (STF/STR).
Used to select the stopping method (deceleration to a stop or coasting) when the start signal turns off.
Used to stop the motor with a mechanical brake, etc. together with switching off of the start signal.
(Refer to section 6.9.3 for stop selection.)
The above parameter can be set when Pr. 160 "User group read selection" = 0.
2-wire type (terminals STF and STR)
A two-wire type connection is shown below.
In the initial setting, the forward/reverse rotation signals (STF/STR) are used as start and stop signals.
Turn on either of the forward and reverse rotation signals to start the motor in the corresponding di-
rection. If both are turned off (or on) during operation, the inverter decelerates to a stop.
The speed setting signal may either be given by entering 0 to 10 V DC across the speed setting input
terminal 2-5, by setting the required values in Pr. 4 to Pr. 6 "Multi-speed setting" (high, middle, low
speeds), etc. (For multi-speed operation, refer to section 6.6.1).
When Pr. 250 is set to any of "1000 to 1100, 8888", the STF signal becomes a start command and the
STR signal a forward/reverse command.
