III. Detailed Product Functions

3.1 Centralized Rectification and Voltage Stabilization Power Supply

The module adopts a high-performance three-phase controllable rectification architecture, which can smoothly convert industrial 380V industrial AC power into a stable 600V standard DC bus voltage, and uniformly supply power to all servo drive modules at the rear end. It is equipped with a large-capacity DC filter capacitor and voltage stabilization control circuit, which can effectively filter out grid noise and voltage spikes, eliminating problems such as unstable servo speed, positioning deviation, and equipment jitter caused by grid fluctuations, ensuring the long-term uniform and stable operation of the multi-axis servo system.

3.2 Four-Quadrant Active Energy Feedback for Energy Saving

Equipped with intelligent energy feedback control algorithm. When the servo motor is in deceleration, braking, or inertia stop conditions, the regenerated electrical energy from the motor is no longer consumed through resistance heating but is directly fed back to the industrial grid for recycling. This significantly reduces equipment heat loss and reduces the cooling load in the workshop. In scenarios with frequent start-stop of lifting, conveying, machine tools, and mechanical hands, the energy-saving effect is particularly prominent, effectively reducing production electricity costs over the long term.

3.3 Multi-Axis Parallel Current Equalization Expansion Networking

Supports parallel operation of multiple 60A0015-5A3-4-00 power modules to achieve current equalization and automatic load distribution, quickly increasing the total power supply of the entire system. The rear end can freely combine 51A010, 51A011, 51A015, etc. with different power servo axis modules to flexibly form 8-axis, 16-axis, 32-axis large-scale distributed servo control systems. The system architecture is simple, with less wiring, and the number of fault points is significantly reduced.

3.4 Comprehensive Electrical Safety Protection

Multiple layers of electrical protection systems are set from the grid input end to the DC output end. Phase loss automatically stops the machine, voltage anomaly quickly locks the output, overload automatically limits the current without reducing the system voltage, and over-temperature automatically reduces power operation. In extreme faults, the main circuit output is directly cut off. All protections are dual monitoring of hardware and software, with fast response speed, providing comprehensive protection for the front-end distribution cabinet, rear-end servo drivers and servo motors, avoiding batch damage of the entire equipment due to abnormal grid conditions.

3.5 Intelligent State Monitoring and Convenient Maintenance

The panel is equipped with power operation indicator lights, fault indicator lights, and feedback status indicator lights, making the operating status clear at a glance. Built-in operation data collection function can monitor core parameters such as input voltage, bus voltage, output current, module temperature, and feedback power in real time. It can be uploaded to the upper-level control system through the communication interface for remote monitoring. The modular design of the entire machine ensures independent separation of the cooling air ducts, making daily dust removal and maintenance simple, and fault diagnosis fast and efficient.

Six, Installation and Usage Tips

6.1 Installation Specifications

Installation location: Install in an independent electrical control cabinet, reserve sufficient space for up and down heat dissipation, do not install in a sealed and narrow space.

Power connection: Connect three-phase 380V power strictly according to phase sequence, reliable grounding, ground wire specification not lower than the main circuit cable.

DC bus connection: Strictly distinguish positive and negative poles, use high-voltage dedicated power cables, shorten the wiring distance and reduce voltage drop.

Heat dissipation environment: Ensure the air duct of the control cabinet is unobstructed, away from frequency converters and high-power heating equipment, avoid hot air direct blowing on the module.

6.2 Debugging Steps

After wiring, check that the three-phase incoming power, DC positive and negative poles, and grounding wire are all correct.

First, connect the control circuit power supply, confirm that the module has no fault alarm and the fan starts normally.

Test the DC bus output voltage under no-load power-on, confirm that it is stable within the standard 600V range.

Connect the subsequent servo axis modules one by one, test the single-axis operation without abnormalities before conducting multi-axis linkage debugging.

Debug the braking feedback condition, confirm that the energy feedback function is normally enabled, without abnormal alarms.

6.3 Daily Maintenance

Regularly clean the dust on the cooling fans and air ducts of the modules to avoid poor heat dissipation due to dust accumulation and high-temperature alarms.

Monthly check the tightness of the main circuit terminal connections to prevent loosening and overheating due to long-term vibration.

Regularly observe the bus voltage and operating current data to predict load abnormalities in advance.

Before restarting after long-term shutdown, conduct insulation and voltage detection to confirm the equipment is in good condition before reusing.
