Press machine controller
0 likes330 views
The document describes the design of a machine controller. It includes: 1) The required motions and actions of the press that the controller must perform, such as stopping or changing direction when various switches are pressed. 2) The components needed for the controller, including an Arduino board, relays, switches, and indicators. 3) The circuit diagram and Arduino program for controlling the press motions based on input from the switches.

![ 8 Output Relay Module (Enabled with 3 ~ 12 Volts) [KIT.8RELAY]
Features:
1) Operating with 12VDC(300mA).
2) Open each relay with 3 ~ 12 volts ( Can be directly connected to
Microcontrollers , Arduino Boards or PC port).
3) Output of each relay can be used for current up to 7A (at 28Vdc or
at 240Vac).
4) Each relay with LED illuminate when the relay is enabled.
5) Dimensions: 100 x 52 mm
6) Easy to connect the wires through PCB screw terminal blocks
(Enlarge the photo to see it clearly).

Press machine controller
- 2. MACHINE CONTROLLER Controller function To design the controller we must know the motions and actions of press well to determine the input and output needed in controller and write the suitable program to do this motions and actions The motions and actions required When press on down switch press will stop the motion in up direction and move downwards When press on up switch the press will stop the motion in down direction and move upwards When stop switch was pressed stop any motion When the press touch the upper limit switch stop motion in upward direction When the press touch the lower limit switch stop motion in downwards direction and move upward Green Led Indicator Light on when power switch is on and off when the Emergency Stop Switch is Pressed Red led indicator light on when Emergency stop Switch is Pressed Yellow Led Indicator light on when the press move downward According to the required motions and actions we designe and programing the circuit whiche achive the required functions
