2.5.2.7 PF (Pump) Motor Drive Circuit
??? IC12/13 (A3956) on B101 Main board are used for driving PF (Pump) motor. In
the IC, Bi-polar drive PWM current control type is performed, making it possible to
provide stable current to each phase of motor. Also, it makes possible to change over
the reference voltage as drive current settings by making few combinations using
current setting ports(input). However, firmware does not support Micro-step in the
EPSON Stylus Scan 2000. The figures below show connection diagram of PF (Pump)
motor drive circuit.
