6.2.11 Printer Motor Drive Circuit

Motor Drive Circuit
The Printer Motor is a Brushless DC Motor. When the nMMP2 signal level goes Low, the Printer Motor starts
rotating. When the Printer Motor reaches a constant speed, the monitor feed back signal, nMMP3 goes Low
and is fed back to the CPU which controls the printing process.
The Printer Motor is powered by a +24 VDC supply. When the interlocks are open, the +24 VDC supply is
cut off and the Printer Motor stops rotating.
