4.4.2 Y-axis Movement (Media Feeding System)
The DC Servo Motor is a brush-commutated DC motor which is responsible for the forward
and backward movement of the Media. This motor is powered by 36VDC. To precise movement of
the media feeding is controlled by a servomotor with a closed-loop feedback signal from the encoder
coupled on the shaft of the motor. The step and direction signal is mainly controlled from the USB
Board and this signal is amplified by the Servo Driver to drive the Servomotor.
4.4.2.1 Servo Driver & Motor
This machine used ACS806 Servo drive and motor as powerplant. The servo driver
installed at the right side behind the Beam, while the servo motor installed at the right side of the
beam. Servo driver is a transfer station, which will get movement signal from USB Board then
control the motor working.
