Used to select the stopping method (deceleration to a stop or coasting) when the start signal (STF/STR)

turns off.

(1) Pr. 250 = "9999"

When the start signal switches off, the motor is decelerated to a stop.

(2) Pr. 250 = other than "9999" (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 had turned off. The
motor coasts to a stop.

9999

0 to 100 s, 9999

Note: 1. The RUN signal turns off when the output stops.

2. When the start signal is turned on again during motor coasting, the motor starts at 0Hz.
