DCI stepper motor driver.


Stage

The provided stage. Marked "DCI MC-001".

Joystick

The stage is meant to be manually controlled via a joystick.

The joystick module is a 2-layer PCB which generates step/direction pulses using one CD4046B PLL IC for each axis. This is clearly a prototype or low-volume product given that there are at least four obvious pieces of rework on the board.

Drive

The drive unit accepts step/direction pulses on a DA-15 D-sub connector. Only six of the 15 positions are loaded, configured as follows. All signals are 5V CMOS logic levels.

Pin number ! Wire color ! Function Black | Ground Orange | +10V power to joystick Yellow | X axis step Green | Y axis step Red | X axis direction Brown | Y axis direction
