11.5 Electric Circuit Description
11.5.1
Tray-up motor control circuit
The tray-up motor (M21) is a DC brush motor driven by the control signal output from the ASIC on the
LGC board and moves up the tray in each drawer.
The motor driver outputs the drive signal (CS1TUMA -0J, CS1TUMB-1J) to the motor based on the
control signal (CS1TUMA-0C, CS1TUMB-1C) output from the ASIC. The motor operates the rotation,
stop or brake according to the status of these drive signals.
