1.Motor Drive Circuit
The Scanner/Printer Motor is a 4-phase uni-polar PM-type step motor. The step signals (A to nB) are
transmitted to IC26 (the Chopper Drive Circuit) by SHINE(IC3). The chopper current is determined by
the voltage at IC26, Pin3 and Pin13. The Motor has two speeds, Slow and Constant. The Motor is
powered by a +24 VDC supply. When the interlocks are open, the +24 VDC supply is cut off and the
Motor stops rotating.
