PC78 Multi-Axis Motion Controller

The PC78 is both a PC/104 motion controller that conforms to the PC/104 ISA bus standard as well as a stand-alone controller via a RS-232 communication port. The PC78 controls up to four axis of step & direction control or +/-10V servo control.  There are up to 12 general purpose TTL I/O bits, 8 of which are user definable.  Non volatile memory macros store programs that can be executed via a command or programmed to an I/O bit signal.  The step pulse is a TTL level 50% duty cycle square wave that supports velocities of 0 through 1,044,000 pulses per second.  The encoder feedback functionality supports quadrature encoders up to 12 MHz at a 4 times the encoder line resolution and is used as closed-loop feedback for the servo and stepper axes or as independent position feedback.  The encoder feedback can provide slip and/or stall detection with programmable dead-band.  Each axis includes dedicated +/- overtravel inputs, a home input, and an auxiliary output.  The controller measures 3.5” x 3.75” for compact applications.  The PC78 was designed for expandability and incorporates an external board to board connector for custom daughter board development.
