Block Diagrams
Below you will find block diagrams for the MY500 JetPrinter.
ZG-031-0046
This diagram provides an overview of the connection plate on the back of
the machine.
ZG-030-0013
This block diagram provides an overview of the electronic, safety and
pneumatic system. A short description of the different subsystems is seen
below:
– Cassette
The cassette subsystem includes a cassette, a piezo drive board
(CTRL-PZD), paste feed (XWG-BRD), and temperature (XWG-
BRD/SAF-CAN air control node) regulation. Communication
between units is done over CAN.
Power is supplied by the amplifier box for the SAF-CAN boards and
by the control box for the remaining boards. The piezo drive and
stepper are kept under control by the safety system. Dispensing is
triggered by an ’Event 0’ signal from the motion system (CTRL-INT).
– Motion
The motion subsystem includes a motion controller board, CTRL-
INT with controller interface, motors, encoders, CTRL-HIP with Z-
amplifier, amplifier box with X/Y amplifiers and safety circuitry.
–Sensor
The sensor subsystem includes a video frame grabber board and a
camera unit including the CAM-DIM board mounted on the X wagon.
Signal chain goes from the PC through CTRL-HIP and XWG-BRD to
the camera unit. Power is supplied by the control box. The laser is kept
under control by the safety system.
– Safety system
When an emergency stop button is pressed down the X and Y motors
will brake and the power is shut off. Power to the conveyor, piezo,
laser and stepper motor is also shut off. A safety switch in the front
hood, which will shut off the power to the devices mentioned above
when the hood is opened. External safety switches can be added to the
AUX EMERG connector on the back of the machine.
Safety relays are closed when all emergency stop buttons are released
and the front hood is closed. A control whether the safety loop is
closed and functional is done before the safety circuit is reset.
– Conveyor
The conveyor subsystem includes a conveyor with four motors
controlled by a CB/CMOT board communicating with software
through the PC's CAN interface board. Power is supplied by the
control box.
All schematics are found on the Documentations CD.
