A system and method are disclosed for determining the minimum required processing speed for a quadrature decoder using measurements of encoder performance, and to assess the safety factor of a particular decoder processing speed. The system and method may also be used to indicate proper adjustment direction by displaying real-time error measurements during encoder alignment. The system measures a logic state width error and calculates alignment parameters, processing speed and a safety factor. The method allows a measured logic state width error to be used to calculate a minimum required processing speed and safety factor.

A Low-Cost Absolute Linear Optical Encoder ('LALOE') for determining the absolute position of a read-head within the LALOE relative to a codestrip is disclosed. The LALOE may include an emitter module within the read-head, the emitter module having a plurality of light sources arranged in an light source pattern and a 90&#xb0; Out-Of-Phase light source; and a detector module within the read-head, the detector module having a plurality of photo-detectors arranged in a photo-detector pattern corresponding to the light source pattern and a 90&#xb0; Out-Of-Phase photo-detector corresponding to the 90&#xb0; Out-Of-Phase light source.

A distributed multi-axis motion control system comprises a multicast communications network having several node components. Each of the node components includes a clock and an actuator. The actuators are part of a motor system and a pattern profile table of the motor system is generated. The pattern profile table is translated into a separate single-direction-of-motion pattern table to separately direct the motion of each of the actuators of the node components. A grandmaster clock generates synchronization signals which are transmitted through the network at a sync interval and which synchronize the clocks. Time-bombs are generated at an interval which is a whole number multiple of the sync interval. The time-bombs cause concurrent execution of the first and subsequent steps from the single-direction-of-motion pattern tables to produce synchronized multi-axis motion of the motor system.
