This is a driving circuit to drive the PF Motor (stepping motor).
This is a driving circuit to drive the PF Motor (stepping motor).
The following illustration shows a simplified circuit.
The following illustration shows a simplified circuit.
The PF Motor is driven by the unipolar constant current chopper method.
The PF Motor is driven by the unipolar constant current chopper method.
The exciting method for the motor is the 1st-2nd phase method.
The exciting method for the motor is the 1st-2nd phase method.
The power to the PF Motor is supplied by turning ON the FET TR3. This is accomplished
by activating the monostable multivibrator IC12. When IC12 is triggered, DTR3 turns ON
and TR3 turns ON.
The power to the PF Motor is supplied by turning ON the FET TR3. This is accomplished
by activating the monostable multivibrator IC12. When IC12 is triggered, DTR3 turns ON
and TR3 turns ON.
TEMPOFF signal is normally at “High” level and the output from IC12 can turn ON TR3 to
24V to the PF Motor. If the PF motor temperature rises excessively, TEMPOFF
signal goes “Low” level, and the output from IC12 is inhibited. Thus,+24V to the PF Motor
is shut off. (For TEMPOFF signal, refer to (3-5) “PF motor temperature sensor”.

PFMA, PFMA, PFMB and PFMB signals are the exciting pulses to drive the PF Motor.
PFMA, PFMA, PFMB and PFMB signals are the exciting pulses to drive the PF Motor.
The digital-to-analog converter (IC4) is used to control the PF motor current. Its output is
controlled by the data sent from the CPU (IC1).
