The JXC73, 83 and 93 are 4-axis controllers for LE's 24VDC step motor driven electric actuators.  Four electric actuators can be controlled within one package, simplifying wiring and economizing space.  Further, the coordination of complex movements is possible.  These movements include 2-axis arc or circular interpolation, 3-axis linear interpolation, and 4-axis speed matching.  The speed
