Figure 9.10: DC-braking time when Stop mode = Coasting
Par. 2.3 = 1 (Stop function = Ramp):
After the Stop command, the speed of the motor is reduced according to the
set deceleration parameters, if the inertia of the motor and load allows that,
to the speed defined with parameter 4.11, where the DC-braking starts.
The braking time is defined with parameter 4.10. See Figure 9.11.
