Selects the stopping method suitable for the application.
Setting Description

1 Coast to stop
2 Coast to stop with timer 1
3 Coast to stop with timer 2
§ Deceleration to Stop (n004 = 0)
Figure 36 Stopping Method
(Deceleration to Stop)
Upon removal of the FWD or REV RUN command, the motor decelerates at the deceleration rate determined by the
time set to decel time 1 (n020), and DC Injection Braking is applied immediately before stop. If the decel time is
short or the load inertia is large, an overvoltage (OV) fault may occur at deceleration. In this case, increase the decel
time or install an optional Braking Resistor (can be equipped with GP5).
Braking torque : Without Braking Resistor : Approximately 20% torque of motor rating
With Braking Resistor : Approximately 150% torque of motor rating
§ Coast to Stop (n004 = 1)
Figure 37 Stopping Method
(Coast to Stop)
Upon removal of the FWD or REV RUN command, the motor starts coasting.
