2.3.4 Feed Motor Control

The feed motor (M2) is a 4-phase stepping motor.
The drive force of the feed motor is transmitted to the feed roller and offset roller via gears
and belts.
The motor driver changes the order and frequencies of the pulse signals (A, A*, B, B*)
output in response to the signal from the CPU, thus controlling the rotation direction and
speed of the feed motor (M2).
