Description of Parameters
Figure 8-44: DC-Braking Time when Stop Mode = Ramp
Par. ID506 = 1; Stop function = Ramp:
After the Stop command, the speed of the motor is reduced according to the set
deceleration parameters, as fast as possible, to the speed defined with ID515, where
the DC-braking starts.
The braking time is defined with ID508. If high inertia exists, it is recommended to use
an external braking resistor for faster deceleration. See Figure 8-44.
