z Stop selection (Pr. 250)
Pr. 250 "stop selection"
Used to select the stopping method (deceleration to a stop or coasting) when the start signal (STF/STR)
switches off.

Setting
Setting Range
250 9999 0 to 100 s, 9999
(1) Pr. 250 = "9999"
When the start signal switches off, the motor is decelerated to a stop.
Time
ON OFF
DC brake
Start signal
Output
frequency
Decelerated when start signal switches off.
Deceleration time (time set in Pr. 8, etc.)
(2) Pr. 250 = other than "9999"
The output is shut off when the time set in Pr. 250 has elapsed after the start signal had switched off. The
motor coasts to a stop.
OFF

RUN signal
Time
Output is shut off when time set in Pr. 250 has
elapsed after start signal had switched off.
Motor coasts to a stop.

ON
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.
