2.3.6 RF Motor Driver Circuit
Figure 2-28 shows a block diagram of the RF motor driver circuit, and Table 2-7 provides the RF
motor specifications. The RF motor is a stepping motor.
The
control circuit
perlbrms
open-loop
phase switching control according to the timing data for acceleration
mnstant
speed, and
deceleration. CPU ports
PG1O
to
PG13
output the motor phase switching signals. The control
method is not equipped with a hold circuit for changing the motor phase. ‘The RF motor rotates
when the carriage moves.
