4. Setup and Wiring

Proper setup and wiring are crucial for the safe and effective operation of the DM800 controller. Refer to the wiring diagrams below for detailed connection instructions.

4.1 Main Controller Unit Overview

Figure 4: DM800 Main Controller Unit with labeled ports.

This diagram illustrates the various ports on the DM800 main controller unit. Key ports include the Ethernet port (1), stepper motor ports (2-6), spindle port (7), output port (8), input port (9), power supply port for system and IO (10, 11), and limited ports (12, 13).

4.2 Port Descriptions

• 1. Ethernet Port: Connects the main controller unit to the handheld control unit.
• 2-6. Stepper Motor Ports: Dedicated ports for connecting stepper motors for X, Y, Z, A, and B/C axes. Each port typically has P+, P-, D+, D- terminals.
• 7. Spindle Port: For connecting spindle control signals (e.g., PWM for speed, direction).
• 8. Output Port: General purpose output interface (e.g., for relays, coolant pumps).
• 9. Input Port: General purpose input interface (e.g., for limit switches, probes).
• 10, 11. Power Supply Port: 24VDC power input for the system and I/O. Ensure current is greater than 1A.
• 12, 13. Limited Ports: Additional input ports, often used for specific limit switch configurations or auxiliary functions.

This image provides a closer look at the Ethernet port (1) on the side of the main unit, and the input (9) and output (8) ports, which are typically DB9 connectors, located on the front face of the unit.

4.3 Power Connection

Connect a stable 24VDC power supply to the designated power input terminals (10, 11) on the main controller unit. Ensure the power supply can deliver at least 1A of current to prevent operational issues.

4.4 Hand Control Connection

Connect the handheld control unit to the main controller unit using the provided Ethernet cable. This establishes communication between the user interface and the motion control system.

5. Operation

The DM800 controller offers various modes of operation for controlling your CNC machine.

5.1 User Interface and Key Functions

The handheld control unit features a 3.8-inch TFT screen and 16 user keys for navigation and control. Familiarize yourself with the key layout and their primary and secondary functions.

Figure 6: Key functions of the DM800 hand control unit (Part 1).

This table details the functions of several keys on the DM800 handheld controller. It includes keys like PAGE (Page Right, Number 1), SHIFT (Second function, Number 2), GOTO 0 (Go to workpiece zero point, Copy, Number 3), HOME (Find machine zero, Delete, Number 0), A (A axis select, Probe, Number 4), B (B axis select, Halve coordinate value, Number 5), MODE (Change MPG mode, Paste, Number 6), and ZERO (Zero, Character M, dot).

Figure 7: Key functions of the DM800 hand control unit (Part 2).

This table continues the description of key functions, covering X (X axis select, Number 7), Y (Y axis select, Number 8), Z (Z axis select, Number 9), CANCEL (Start and Stop Spindle), ENTER (A axis manual reverse, Probe, Number 1, Move left), SPINDLE (Y axis manual forward, Select Y axis, Number 2, Move up), START (X axis manual forward, Select X axis, Number 3, Move left), and PAUSE (Start the G code).

5.2 Loading G-Code Files

The DM800 supports direct loading of G-code files from a USB stick. Insert the USB stick into the designated USB port on the handheld controller. Navigate through the menu on the TFT screen to select and load your desired G-code file for execution.

5.3 Manual Operation Modes

The controller supports several manual operation modes:

• Ready Mode: Allows for general operations, including processing, value modification, or initiating other modes.
• Reset Mode: Stops all current operations.
• Step Mode: Enables manual step-by-step movement for each axis.
• MPG Mode: Utilizes the Manual Pulse Generator (MPG) handwheel for precise, incremental movement of each axis.

5.4 Adjusting Speed (SRJ Value)

When operating in manual mode, the current speed can be adjusted by modifying the SRJ value. The formula for current manual speed is: Current manual speed = Setting manual speed * SRJ.

Definitions of common parameters:

• F: Feed speed, unit is mm/min. Example: F=2000 means 2000mm feeding per minute.
• S: Spindle Speed, unit is revolutions/min. Example: S=20000 means 20000 revolutions per minute.
• X, Y, Z, A, B, C: Axis Coordinates.

6. Maintenance

To ensure the longevity and optimal performance of your RATTMMOTOR DM800 controller, follow these maintenance guidelines:

• Cleaning: Regularly clean the exterior of both the hand control unit and the main controller unit with a soft, dry cloth. Avoid using abrasive cleaners or solvents.
• Environmental Conditions: Operate and store the controller in a clean, dry environment, free from excessive dust, moisture, and extreme temperatures.
• Cable Inspection: Periodically inspect all cables for signs of wear, damage, or loose connections. Replace damaged cables immediately.
• Software Updates: Check the manufacturer's website for any available firmware updates to ensure your controller has the latest features and bug fixes.
