US 11,536,592 B2 · Position encoder controller

Abstract

A controller for use with a position encoder includes one or more motion inputs suitable to couple to motion outputs of the position encoder and a limit input suitable to couple to a limit output of the position encoder. The controller also includes an actuator interface, a command interface, and circuitry coupled to the one or more motion inputs, the limit input, the actuator interface, and the command interface. The circuitry is configured to receive a command through the command interface to move a structural member coupled to the position encoder to a new position and control an actuator through the actuator interface to move the structural member toward the new position. A limit indication is received from the position encoder through the limit input and the controller stops or reverses the movement of the structural member by controlling the actuator in response to receiving the limit indication.

Dependent claims

A controller for use with a position encoder, the controller comprising:

one or more motion inputs suitable to couple to motion outputs of the position encoder;
a limit input, separate from the one or more motion inputs, suitable to couple to a limit output of the position encoder;
an actuator interface;
a command interface to receive commands;
and
circuitry coupled to the one or more motion inputs, the limit input, the actuator interface, and the command interface, the circuitry configured to:
receive a command through the command interface to move a structural member coupled to the position encoder to a new position;
control an actuator through the actuator interface to move the structural member toward the new position;
receive a limit indication from the position encoder through the limit input;
and
stop or reverse the movement of the structural member by controlling the actuator through the actuator interface in response to the receiving of the limit indication.

An article of manufacture comprising at least one non-transitory computer-readable storage medium having computer-readable instructions stored thereon that, when executed by a processor acting as a controller for use with a position encoder, cause the processor to:

receive a command to move a structural member coupled to the position encoder to a new position;
control an actuator to move the structural member toward the new position;
receive a limit indication from a limit output of the position encoder that is separate from one or more motion outputs of the position encoder;
and
stop or reverse the movement of the structural member toward the new position by controlling the actuator in response to the reception of the limit indication.
