Start/Stop / End Volt
This parameter makes it possible to set the voltage level
where the stop ramp ends. The voltage or the torque will
decrease from full voltage to this level and then cut the power
to the motor. This function will be active only if parameter
Stop ramp is used.

End Volt 30%
Path in menu:
Menu/SETTINGS/Functional Settings/
Start/Stop / Step Down
When stopping a motor using the stop ramp, the speed will
not decrease immediately. The step down voltage function
makes it possible to set a level where the motor speed
decreases as soon as the stop ramp begins. By this, a more
optimized stopping of the motor is achieved. This function is
not available when the stop mode is set to "torque"
