4-3 Special Circuit Description
4-3-1 Power Circuit
This system is operated under 100Vac or 240Vac. The power circuit supplies the three differential DC voltage
sources.
1) Feed, Auto Cutter Motor Voltage, TPH Driving Voltage : +24VDC
+24VDC is supplied from SMPS.
This voltage is used as a Step motor driving voltage and a source voltage of the other voltage sources and
TPH Driving Voltage.
2) IEEE1284 Logic IC Voltage : +5VDC
Change the input +24VDC to +5VDC by a regulation. U7(A4490EESTR)
No.
