Selects the stopping method suitable for application.

Deceleration to stop
Example: when accel/decel time 1 is selected

Upon termination of the FWD (REV) run command, the motor decelerates at the decel
rate determined by the time set to decel time 1 (n020) and DC injection braking is
applied immediately before stop. DC injection braking is also applied when the motor
decelerates by setting frequency reference lower than minimum output frequency
(n016) with FWD (REV) run command ON.

If the decel time is short or the load inertia is large, over voltage (OV) fault may occur
at deceleration. In this case, increase the decel time or install a optional braking
resistor.

Braking Torque: Without braking resistor: Approx. 20% torque of motor rating

With braking resistor: Approx. 150% torque of motor rating
