Focusing on the selection, maintenance, parts, and second-hand distribution of HSR ROBOT equipment, we answered the most frequently asked questions from customers.
What control systems and teach pendants does HSR Robotics use?
Relying on Huazhong CNC's technological background, HSR Robotics' official product center lists motion controllers, servo drivers, servo motors, and teach pendants as core self-developed components; On the software side, HSR-Studio companion tools are provided. Public parameters for models like JR605: body-control cabinet connection cable 3-5m, teach pendant cable 8m, control cabinet I/O of 32 inputs / 31-32 outputs. Digital measurement specifications can be used to troubleshoot peripheral wiring faults.
What are the common alarm alerts for this type of JR612-1600 aircraft?
Based on the publicly available parameter table, common alarms focus on: servo overcurrent/overload (abnormal load or balance cylinder), overtravel (improper J2/J3 soft limit settings), encoder communication faults (oxidation and looseness of the 5m cable plug between body and cabinet), and dust conduction alarms at the control cabinet's IP20 protection level. It is recommended to follow the alarm code and refer to the included manual, and confirm recurring issues with on-site diagnosis.
How to troubleshoot for CR collaboration series drag teaching not responding or collision false alarms?
The CR series official website annotates support for collision detection and drag-and-pull teaching. First, confirm that the drag-and-teach mode in the software is enabled, and that the tool load and center of mass parameters have been calibrated according to actual conditions; Collision false alarms are common when cable drag chains have excessive restraint force, zero-position drift, or sensitivity settings are too high. If the abnormality persists after excluding parameter factors, it is mostly due to joint torque sensing or harmonic module issues, requiring on-site inspection and confirmation.
How often should the battery of HSR robot encoders be replaced? What should you do if you lose power or lose zero points?
The absolute value encoder is based on the battery's position data. After a low voltage alarm, the battery should be replaced as soon as possible while the control cabinet is powered on (model is subject to included information). If the battery is removed for too long, zero points may be lost, so calibration of each shaft's zero points must be done according to the manual process; If J1-J6 multi-axis simultaneous loss or calibration fails, it is recommended that technicians handle it on-site to avoid accidental operation and worsening the fault.
How is the lubrication and maintenance cycle for reducers determined?
HSR's official website does not disclose a unified fat change cycle. JR heavy-duty models use full gear rigid transmission, with industry practice of lubrication status checks every 1-2 years or by operating hours, shortening the cycle under heavy load, high duty cycle; If abnormal noises, local temperature rise, or accuracy deterioration occur, stop the machine immediately for inspection. The grease grade and dosage should be based on the user manual for the corresponding model. If unsure, confirm with on-site diagnosis.
Control cabinet protection rating IP20/IP54. How should it be installed on site?
Public parameters show the JR series control cabinet standard protection IP20, with an optional IP54 rating. In machining, grinding, and welding workshops, there is a lot of oil mist and dust. IP20 cabinets should be placed in independent electrical control cabinets/positive pressure cabinets, and fan filters should be cleaned regularly; For cutting fluid mist applications, choose IP54 and check the sealing strip. The installation method for vertical or horizontal cabinets should follow the manual. Insufficient heat dissipation spacing will trigger an over-temperature alarm.
What should I do if the I/O points are insufficient or the signal is unstable?
The JR series control cabinet provides around 32DI/32DO, with the main unit retaining a 12-position aviation plug signal wire and one Φ6-Φ8 air circuit. Expansion can be equipped with remote IO or via fieldbus (subject to controller support protocol); If the signal is unstable, first check the oxidation of the aviation plug pins and the single-end grounding of the shielding layer. After ruling out wiring factors, locate the controller I/O board fault.
