4. Setup and Wiring Instructions
Proper wiring is crucial for the safe and correct operation of the DDCS Expert CNC Controller. Please follow the diagrams and instructions carefully. Always ensure power is disconnected before making any wiring changes.
4.1 Power Supply Wiring
The controller requires a 24V DC power supply with a minimum current of 0.5A. Ensure proper grounding (PE) and consider using EMI filters for stable operation. The system typically uses two separate 24V DC power supplies, one for I/O power and one for system power, each connected through an EMI filter. The positive (COM+) and negative (COM-) terminals of the power supplies connect to their respective inputs on the controller. The PE (Protective Earth) terminal should be properly earthed.
Note: The visual diagram for power supply wiring is not available for embedding. Please refer to the textual description and the full product manual for detailed instructions.
4.2 Spindle Wiring Example
Image: Diagram illustrating the wiring for a spindle motor connected to an inverter, which is then connected to the DDCS Expert controller's spindle output terminals (ACM, PWM, VSO, COM-, FOR).
This diagram shows a typical connection for a spindle motor controlled via an inverter. Connect the inverter's control signals (e.g., analog voltage for speed, forward/reverse) to the corresponding spindle control terminals on the DDCS Expert (ACM, PWM, VSO, COM-, FOR). Ensure the spindle motor is correctly connected to the inverter's output.
4.3 Multi-Speed Spindle Wiring (Application Scenario)
Image: Detailed wiring diagram for a multi-speed spindle setup, showing connections from the DDCS Expert's output ports (OUT01-OUT20) to various components including a drive optocoupler, inductive load relay, and servo/step drivers. It also shows input ports (IN01-IN24) for proximity switches and mechanical switches, and power supply connections. This diagram represents a comprehensive application scenario.
For complex multi-speed spindle configurations and general application scenarios, refer to this detailed wiring diagram. It illustrates how various input and output ports are utilized to control different functions, including spindle speed, tool magazine operations, and safety interlocks. This diagram also shows the internal logic for input ports (e.g., NPN proximity switches, mechanical switches) and output ports (e.g., drive optocouplers, inductive load relays).
4.4 Stepper/Servo Driver Connection
Image: Diagram showing how a stepper motor and its driver connect to the DDCS Expert controller. The driver receives PUL+, PUL-, DIR+, DIR-, ALM+, ALM- signals from the controller and connects to the motor. A separate DC power supply is shown for the driver.
Connect your stepper or servo drivers to the DDCS Expert using the pulse (PUL) and direction (DIR) signals. Ensure the driver's alarm (ALM) signals are also connected if applicable. Provide a separate power supply for the motor driver as indicated.
4.5 Limit, Home, and Probe Inputs
Image: Wiring diagram for connecting proximity switches (S1, S2) and a mechanical switch (S3) for limit, home, and probe functions to the DDCS Expert's input terminals (IN01-IN24). The diagram shows connections to IN11, IN12, IN13, IN14, IN15, IN16, IN17, IN18, IN19, IN20, IN21, IN22, IN23, IN24, and COM+.
The limit switches should be NPN Normal Open type, operating within a 24V DC voltage range. Connect proximity switches (S1, S2) and mechanical switches (S3) to the designated input terminals (e.g., IN11-IN24) and the common positive (COM+) as shown in the diagram.
4.6 MPG Wiring
Connect the MPG (Manual Pulse Generator) to the dedicated MPG port on the controller. The MPG port is a 15-pin D-sub connector. The pin assignments are as follows:
| Pin No. | Mark | Definition | Notes |
|---|---|---|---|
| 1 | +5V | Power Supply + | MPG power supply input positive terminal |
| 2 | A+ | Encoder A Phase + | MPG A phase differential input positive terminal |
| 3 | B+ | Encoder B Phase + | MPG B differential input positive terminal |
| 4 | XIN | Select X Axis | Connect with GND, then X axis is selected |
| 5 | ZIN | Select Z Axis | Connect with GND, then Z axis is selected |
| 6 | X100 | X100 Ratio | Connect with GND, then X100 ratio is selected |
