An apparatus is provided for controlling the execution of functions associated with the automatic operation of a manipulator. While traditional function execution has been associated with arrival of a workpoint at or proximate to a predetermined point, the present invention provides for plural function execution between predetermined points. Two alternative embodiments are provided: a first embodiment controls a single output interface type and is unrelated to functions associated with predetermined points; a second embodiment provides multiple executions of any function normally associated with a predetermined point. Spacing between function executions associated with either embodiment is controlled as a function of distance specified by the operator. To produce a desired spacing, feedrate reduction is automatically effected in the event a programmed feedrate is incompatible with a specified function execution interval.

Control system for program controlled manipulator having multiple

A method and apparatus for controlling a split axis servo mechanism are provided. Each of the two servo mechanisms is responsive to a single machine member motion command for effecting linear motion of a machine gantry. Velocity skewing of the servo mechanisms is corrected by modifying the gain of one of the servo mechanisms in response to the difference between the actual positions of both. The gain modification effects reduction of the magnitude of the actual position difference.
