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

When the Pr. 250 value is any of 1000 to 1100 seconds, 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. 1000 seconds) 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.
