Abstract: A servomotor controller provides nut runner and other functions in a set of stackable modules. Extended-function modules can be added into and removed from the stack as needed. Destacking of closely spaced, wall-mounted controllers can be performed without demounting. Module assemblies are dripproof. Multiple sizes of nutrunner driver electronics and multiple keyboard and display options can be selected. A reprogrammable central processor can identify newly installed or removed features within a controller and reconfigure itself F accordingly. Stackable modules include Ethernet(®, multiple-bit I/O, and proprietary interfaces for many industries. The other modules communicate with the processor module via a backplaneless bus architecture. The central processor supports master/satellite group operation, whereby one controller unit can command multiple others, and whereby a higher-level system can command multiple controllers or multiple master/satellite controller groups.

Abstract: A paint spray apparatus includes a plurality of paint sprayers installed in a paint spray booth. Each paint sprayer includes a paint spray head pivotably mounted on the end of a movable paint spray arm. The paint spray arm and paint spray head are movable on multiple axes by servo motors, which are controlled by servo drives mounted on or beside the paint sprayer. The spray of the paint spray head is controlled by a plurality of proportional solenoid valves mounted on the paint sprayer. The movement and spray of the paint sprayers are controlled by a computer having an interface to an optical fiber. The optical fiber connects the computer to the servo drives in series in a token ring network.
