Abstract
A control apparatus for multiplexing a single distributed control amplifier to control multiple axes of motion in a multi-axis machine. In one example, the control apparatus comprises a distributed control motor amplifier, a first motor constructed and arranged to provide movement along a first axis of motion, a second motor constructed and arranged to provide movement along a second axis of motion, a first relay having a switch coupled to the distributed control motor amplifier, a first contact coupled to the first motor, a second contact coupled to the second motor, and an input for receiving an actuation signal, wherein the relay is configured to be manipulated between a first state in which the switch is electrically connected to the first contact a second state in which the switch is electrically connected to the second contact, in response to the actuation signal.
