Six. Installation and usage key points

6.1 Installation requirements The entire machine is installed in a standard industrial control cabinet with good ventilation and heat dissipation conditions. Adequate space for heat dissipation is reserved around it. Installation in a sealed and narrow space is prohibited. The three-phase main circuit incoming lines are strictly distinguished by phase sequence and firmly and reliably grounded. The positive and negative poles of the DC bus are strictly distinguished, and large-sized high-voltage power cables are selected for laying to shorten the wiring distance and reduce line voltage drop. When multiple units are used in parallel, copper busbars are uniformly connected to the busbars, and the communication bus is networked in accordance with the standard.

6.2 Debugging Process

After completing all wiring work, check the main circuit, control circuit, and grounding lines item by item to ensure there are no errors.

Firstly, connect the 24V control power supply to confirm that the equipment self-check is normal without fault alarms and that the cooling fan starts normally.

Apply three-phase main electricity without load to observe that the output voltage of the DC bus is stable within the standard 600V range.

Connect the rear-end servo drive module to complete the no-load trial operation of a single device to verify the voltage stabilization and basic output functions.

Gradually load for testing, debug the energy feedback function, overload current limiting function, and various protection functions.

Full-line linkage debugging to confirm that the multi-axis synchronous operation, load distribution, and feedback energy saving are all functions operating normally.

6.3 Daily Maintenance and Care

Regularly clean the dust on the ventilation ducts and fan surfaces of the equipment to avoid dust blockage causing poor heat dissipation and high-temperature alarms; monthly tighten the large current connection terminals of the main circuit to prevent long-term vibration from loosening and heating; regularly check the operating parameters of the equipment, such as current and busbar voltage, to predict abnormal loads in advance; before restarting after long-term shutdown, complete the insulation detection and voltage detection of the lines to confirm the equipment is in good condition before reusing it.
