8.8 Tandem LCF tray-up motor / end fence motor
The tandem LCF tray-up motor and end fence motor, which are DC motors driven by the control signal
output from the PFC CPU on the LGC board, move the tray up in the tandem LCF and shift the end
fence.
The motor driver outputs the drive signal (TLTRM-0/1A, TLTMM-0/1A) to the motor based on the control
signal (TLTRM-0/1, TLTMM-0/1) output from the PFC CPU. The motor operates the forward rotation,
reverse rotation, brake or stop according to the status of these drive signals.
