2.5.3 Stack Slide Motor Control

The stack slide motor (M3) is a 4-phase stepping motor. This motor can rotate in only one
direction due to the machine configuration. Movement of the stack slider is controlled using
the cam driven by the stack slide motor (M3). The motor driver controls operation of the
stack slide motor (M3) with the pulse signals (A, A*, B, B*) output in response to the signal
from the CPU.
