Setting 0: Ramp to Stop
When the Run command is removed, the drive will decelerate the motor to stop. The
deceleration rate is determined by the active deceleration time. The default deceleration time
is set to parameter C1-02.
DC Injection braking (for IM control) or Short Circuit Braking (PM Open Loop Vector) can
be applied at the end of the ramp in order to completely stop high inertia loads. Refer to
Refer to b2: DC Injection Braking on page 47 for details.
