(1)Pr. 250 = "9999"
When the start signal switches off, the motor is decelerated to a stop.

(2)Pr. 250 = 0 to 100 seconds (output is shut off after preset time)
The output is shut off when the time set in Pr. 250 has elapsed after the start signal
was switched off. The motor coasts to a stop.

When the Pr. 250 value is 8888, the functions of terminals STF and STR change as
shown below:
STF = start signal, STR = rotation direction signal
STF STR Inverter Operating Status
OFF OFF
OFF ON
Stop
ON OFF Forward rotation
ON ON Reverse rotation
When the Pr. 250 value is any of 1000 to 1100s, the functions of terminals STF and
STR are the same as when the Pr. 250 value is 8888.
Also, for the stopping method used when the start signal switches off, the output is shut
off (the motor coasts to a stop) after the period set in Pr. 250 (i.e. 1000s) have elapsed.
Note:1. The RUN signal switches off when the output stops.
2. When the start signal is switched on again during motor coasting, the motor
starts at 0Hz.
3. When the Pr. 250 value is 0, the output is shut off within the shortest time.
