2.4.4 Pickup motor (M2)control
A control block diagram of the pickup motor (M2) is shown below. The pickup motor is
a four-phase stepping motor. This circuit mainly implements the following kinds of control:
• Motor ON/OFF control
• Motor revolution direction control
• Motor revolution speed control
F02-204-07
The CPU (IC1) mounted on the ADF controller PCB receives print mode communications
data (such as scale, operation mode, and timing) from the host as commands. It generates
driving pulses to the pickup motor on the basis of these commands.
As a stepping motor, the pickup motor has the direction and speed of its revolution con-
trolled by varying the output order and frequencies of (M2A¥M2A*¥M2B¥M2B*).
