2.3.2.4 PF Motor Driver Circuit
The
motor for this printer operates the following:
Paper loading
Paper feeding
The gate array E05B33 (IC6) outputs the phase drive control signals (PFAPH and PFBPH), phase data
signal (PFA0/1 and PPFB1/0) and voltage reference data (PFV) to the driver IC UDN2917EB (IC17). The
driver IC then controls the phase current based on the voltage reference data. This sequence enables the
micro step with a minimum of 1/720 inch at 2-2 phase.
