6.2.6 Transmit Motor Control Circuit
The transmit motor is a PM type, two-phase bi-polar motor. The stepping signal and chopping current
control signals (pTAPH, pTBPH, pTA10, pTA11, pTB10 and pTB11) are sent to the chopper drive circuit,
comprised of IC36, IC37 and its peripheral circuitry, from IC3 SHINE output port. The motor is powered by
+24 VDC and is driven by a 1/2-phase excitation, and greater step division is provided by controlling the
phase circuit in steps (micro-step control).
