Parameter ID 506 = 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 parameter ID 515, where the DC-braking starts.
The braking time is defined with parameter ID 508. If high inertia exists, it is recommended to use an external brake resistor for faster
deceleration.
