Abstract
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.
