5. Setup

5.1 Unpacking and Inspection

Carefully remove the rotating platform from its packaging. Inspect the unit for any visible damage that may have occurred during transit. Report any damage to your supplier immediately.

5.2 Mounting the Platform

The HT03RA100 can be mounted horizontally or vertically. Ensure the mounting surface is flat, stable, and capable of supporting the platform's weight plus any applied load. Use appropriate fasteners through the designated mounting holes. Refer to the dimensional drawings in Section 8 for precise mounting hole locations and sizes.

5.3 Electrical Connection

The platform utilizes a standard stepper motor with a DB9 interface for control. Connect the DB9 cable from the platform to your motion controller (e.g., PLC, single-chip machine, or sports board card). Ensure the controller is compatible with the stepper motor's specifications (1.8° step angle). The system is designed for flexible controller integration, allowing for customized motion systems.

The platform requires pulse signals to drive the stepper motor. Consult your motion controller's manual for specific wiring and programming instructions.

6. Operation

6.1 Basic Rotation

Once connected to a compatible motion controller, the platform can perform 360° continuous rotation. Control the rotation direction, speed, and angular position by sending appropriate pulse signals and commands from your controller.

6.2 Utilizing Limit and Zero Functions

The platform supports the addition of limit and zero functions. These functions allow you to define the operational range and establish a home position for precise, repeatable movements. Refer to your motion controller's documentation for configuring these features.

6.3 Understanding Resolution and Speed

The platform offers high resolution for fine angular adjustments. The resolution per pulse is 0.01° without subdivision, and 0.0005° with 20 subdivisions. The maximum rotation speed is 25° per second. Adjust these parameters via your motion controller to suit your application's precision and speed requirements.

7. Maintenance

Regular maintenance ensures the longevity and optimal performance of your rotating platform.

• Cleaning: Keep the platform clean and free from dust and debris. Use a soft, dry cloth for cleaning. Avoid using harsh chemicals or abrasive materials.
• Inspection: Periodically inspect the worm gear, bearings, and motor connections for any signs of wear or looseness.
• Lubrication: The worm gear mechanism is designed for long-term operation. Consult with TBVECHI support if lubrication is deemed necessary, as improper lubrication can affect performance.

8. Troubleshooting

If you encounter issues with your HT03RA100 platform, refer to the following common troubleshooting steps:

• Platform not moving:
  • Check power supply connections to the stepper motor.
  • Verify the DB9 cable connection to the motion controller.
  • Ensure the motion controller is sending correct pulse signals and commands.
  • Check for any physical obstructions preventing movement.
• Inaccurate positioning:
  • Confirm the resolution settings in your motion controller match the platform's specifications.
  • Check for any backlash or lost movement. Refer to specifications for expected values.
  • Ensure the platform is securely mounted and not experiencing vibrations.
• Unusual noise during operation:
  • Inspect for any loose components or foreign objects.
  • Verify the motor is connected to the worm gear via the high-quality elastic coupling as intended.

If problems persist, contact TBVECHI customer support for further assistance.
