Abstract
An actuator comprising a single actuator housing containing within it a motor, a controller, a memory, and a position sensor having an output, a user interface for causing a first threshold value to be stored in the memory, and the controller configured and arranged to stop the motor as a function of the position sensor output and the first threshold value.
Claims28
An actuator comprising:
- a single actuator housing containing within it a motor, a controller, a memory, and a position sensor having an output;
- a user interface for causing a first threshold value to be stored in said memory;
- and
- said controller configured and arranged to stop said motor as a function of said position sensor output and said first threshold value.
The method of controlling an actuator comprising the steps of:
- providing an actuator having a single actuator housing containing within it a motor, a controller, a memory, a position sensor having an output, and a user interface for causing a first threshold value to be stored in said memory;
- receiving a signal over said user interface;
- storing a threshold value in said memory;
- reading a position sensor output;
- calculating a current position value, said position value being a function of said position sensor output;
- and
- preventing said motor from moving as a function of said current position value and said threshold value stored in said memory.
The method of controlling an actuator as set forth in claim 21, wherein said step of preventing a motor from moving comprises the step of stopping said motor when said current position value is greater than said first threshold.
