Parts of the control system
Point at a number or a part of the drawing.
Screen and keys where the operator sets and watches the machine. It talks to the CPU board over a cable.
Runs the machine program: it reads the inputs, steps through the cycle and sends commands to the valves, heaters and drives.
Connect the CPU to the machine: inputs from switches and sensors, outputs to valve solenoids, contactors and heater relays.
Passes speed and pressure commands from the CPU to the servo drive or inverter and reads back its status.
Turns the cabinet supply into the regulated DC voltages that the boards, sensors and valve coils run on.
Powers and controls the servo motor that drives the hydraulic pump, following the commands from the drive interface board.
The wiring from switches, sensors, valves and heaters lands here and runs through the cable duct to the I/O modules.
