TRAY 2 FEED/LIFT UP
MOTOR
Digital Output [072-001] Rotates the Motor forward. (in the Feed direction. 2-phase excitation)
Rotates the Motor reverse. (in the Lift-up direction. 2-phase excitation)
Digital Output [072-002]
However, if Level Sensor is ON when the motor starts driving, it does not operate.
6
Digital Output [072-003] Rotates the Motor forward. (in the Feed direction. 1-2-phase excitation)
Digital Output [072-004] Rotates the Motor reverse. (in the Lift-up direction. 1-2-phase excitation)
However, if Level Sensor is ON when the motor starts driving, it does not operate.
