6.8.3 Stop selection (Pr. 250)
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. You can also select the operations of the start signals (STF/STR). (Refer to
section 6.9.4 for start signal selection.)
The above parameter can be set when Pr. 160 = 0.
Set Pr. 250 to "9999" (initial value) or "8888". The motor decelerates to a stop when the start sig-
nal (STF/STR) turns off.
