App note from Holtek on their HT7K1xxx series drive control that replace limit switches but uses speed reduction instead when controlling motor actuation. Link here (PDF)
In actuator applications, when a valve or an actuator has reached the end of its stroke, the motor input power will be switched off using a limit switch. This is called mechanism control. If the motor runs at full speed from start to stop during the whole stroke, this may cause the motor to hit the end of its stroke without reducing speed when the limit switch is triggered. There are two main problems here in using mechanism control. One is aging of the limit switch and the other is that a collision will occur when the valve or the actuator reaches the end of stroke without speed reduction, which could cause damage to the gear mechanism.
