Focusing on the selection, maintenance, spare parts, and second-hand distribution of Topstar equipment, we answer the most frequently asked questions from customers.
What model is TOPSTAR's robot control system? How do you report to the police?
According to public information on the official website, it masters three core technologies: control, servo, and vision. SCARA uses an integrated drive-control system, but the specific model name of the controller has not been disclosed. On-site troubleshooting is recommended to first record the alarm code and operation on the teaching side, verify the heat dissipation and power supply of the integrated drive and control cabinet (voltage fluctuations are common triggers), and then handle according to the included alarm table; For system-level faults, on-site diagnosis and confirmation are required.
What does the -S/-H suffix mean in Tuo Xingyun's six-axis configuration? Can spare parts be interchanged?
According to the models sold on the official website (such as TRH010-600-400-S and -H, TRV025-1800-H), there are two suffix versions for the same arm reach, usually corresponding to standard/high-speed or different load configurations. For specific differences, please refer to the product information PDFs for each model. Spare parts such as joint motors and reducers may not have interchangeable suffixes. When purchasing, the nameplate model matches the entire machine, and if you can't get it accurately, confirm it with on-site diagnosis.
SCANA does not have a list of repeatability on the official website. How can I verify it?
The basic information on the details page of the Tuoxingchen TRH/TRD series only lists arm span and rating/maximum load. For accuracy, please download the corresponding model's 'Product Information' PDF or request the manufacturer's specification for confirmation; The Tuoxingyun six-axis detail page discloses ±0.02-±0.05mm values. When accepting or redesigning modifications, do not use the same series as presumption; use the factory inspection data of that model as the standard.
How to handle encoder battery leakage, power loss, and loss of zero position?
Common approach for collaborative and industrial robots: Low battery voltage triggers a position loss alarm; after replacing the battery pack with the upper power on the upper position, zero calibration is performed to restore the absolute position. TOPSTAR's included manual does not disclose battery specifications; confirm battery assembly diagrams by full machine model before replacement; If multiple axes lose zeros simultaneously or calibration repeatedly fails, encoder hardware may be involved and must be confirmed together with on-site diagnosis.
How often should robot reducers (RV/harmonics) be maintained?
The official website publicly discloses maintenance information about 'specialized robot maintenance/health checkups' but does not publish a unified fat replacement cycle. Industry practice is to perform lubrication inspections based on operating hours (about 15,000-20,000 hours) or 1-2 years, with shorter high-load high-speed operating conditions; If abnormal noises, temperature rise, or deterioration in repeated positioning accuracy occur, stop the machine immediately for inspection. The specific grease grade and oil quantity should follow the corresponding TOPSTAR manual.
How to prevent wiring wear on TRV hollow arm models?
When the hollow arm passes through the welding gun cable/air tube, the J6 rotating section repeatedly twists and easily causes fatigue. It is recommended to use internal wiring according to the official website's mid-size model design intent, reasonably set odd shape avoidance and J6 slewing limits, select bend-resistant cables, and reserve maintenance length; The initial sign of disconnection is communication interruption or occasional alarm during operation, which should be confirmed with on-site diagnosis to confirm the wear point.
How to troubleshoot if the teach pendant/upper-level software cannot connect to the robot?
First, verify that the computer and robot are on the same network segment and have no IP conflicts when the network cable is directly connected, then turn off the firewall and try again. Wireless connection checks AP signal and port occupancy; If multiple devices cannot connect simultaneously, prioritize checking for changes in the on-site network switch and IP address. If none of the above are effective, it may be a fault in the controller's communication module and should be confirmed together with on-site diagnosis.
