◆
1: Coast-to-stop
After receiving the stop command, the ac drive stops output immediately and the load
stops under the effects of mechanical inertia.
◆
2: Dec-to-stop +DC injection braking
After receiving the stop command, the ac drive reduces its output frequency according
to the Dec time and starts DC injection braking when its output frequency reaches the
preset frequency of braking.
Refer to the Notes of P1.09

P1.12 for the functions of DC injection braking.

Note:
◆
DC injection braking is injecting DC current to motor, to let it stop quickly, and keep
the spindle of motor in standstill until finished DC injection braking
