SR500A-360/2.83 model positioning and working condition adaptation
SR500A-360/2.83 It belongs to the Siasun SR series heavy-load/ultra-heavy load industrial robot model, with a rated load of 360kg, a motion radius of 2833mm, and a repeatability of ±0.1mm. Siasun Robotics' technical foundation is rooted in the Chinese Academy of Sciences, with strong expertise in clean robots and semiconductor equipment, and deep expertise in special robots (vacuum/cleanroom/explosion-proof); The control platform is the SIASUN platform, and the program ecosystem is graphical + script programming.
From the perspective of working condition adaptation, typical applications for heavy-duty (360kg) positioning are:Vehicle body handling, large casting processing, building materials and heavy palletizingCommon application processes for this model include handling, palletizing, spot welding, and loading and unloading. The extra-long reach (2833mm) is suitable for large workpieces and cross-line services, with attention to stiffness and vibration during large overhanging postures. ± 0.1mm repeatability meets handling and palletizing conditions; For precision assembly applications, it is recommended to use visual guidance for a closed-loop position. For heavy-duty models, the foundation is poured according to the manufacturer's drawings and settlement observation is conducted, with hoisting and maintenance space reserved during the layout phase.
| Parameters | Engineering interpretation and usage recommendations |
|---|---|
| Rated load capacity: 360kg | It is recommended to reserve a load margin of 20%–30%; Verification is made by combining end self-weight + workpiece + imbalanced load inertia, especially sensitive to high-speed conditions |
| Radius of movement: 2833mm | Determine the radius of the workcell layout: bins, tooling, and fences are bounded by maximum arm span + safety distance; Verify the accessibility of each pick-and-place point during cross-station service |
| Repeatability: ±0.1mm | Repeatability ≠ absolute accuracy: Precision assembly requires external measurement closed-loop or visual guidance; Long-term accuracy trends rely on annual retest management |
| Number of axes: 6 | Six-axis all-posture capability, the preferred choice for complex trajectory and inclined surface operations |
| Protection rating: IP67 | Resistant to dust and washing environments (suitable for food and beverage, casting and grinding stations) |
| Controller: SIASUN Controller (SIASUN platform) | Decide on the process ecosystem, spare parts channels, and second-hand residual value; Currently, spare parts channels are smooth, and repair and upgrade paths are mature |
Control systems and common failure modes
The SR500A-360/2.83 is equipped with the SIASUN platform controller, with a graphical + scripted programming language and development environment. Maintenance of this generation of control platforms focuses on three basic components: power, storage, and cooling—most "sudden downtime" can be detected in advance when preventive maintenance is in place.
| Failure mode | Typical performance | Disposal recommendations |
|---|---|---|
| Aging of seals in clean machine models | Aging of Cleanroom Seals (Risk of Excessive Particle Limits) | Included as a mandatory inspection item for annual maintenance, with spare parts stocked in advance |
| Driver and power module failure | Driver and power module failure | Initial interpretation of alarm codes by reference with manuals, remote diagnosis allows for early positioning |
| Loss of specialized parts for vacuum environments | Vacuum environment special parts wear (sealing rings, lubrication drying out) | Daily inspection coverage, with abnormal trends (abnormal noises/temperature rise/errors) recorded |
| Faults in the teach pendant and communication cables | Faults in the teach pendant and communication cables | Quarterly dust removal maintenance and cabinet temperature monitoring |
| Maintenance projects | Cycle recommendations | Key points |
|---|---|---|
| Clean machine models are maintained according to cleanroom procedures (tool cleaning, particle retesting). | According to the manufacturer's manual cycle | Clean machine models are maintained according to cleanroom procedures (tool cleaning, particle retesting). |
| Seals must be replaced periodically | By cycle | Seals must be replaced periodically |
| OEM specifications for vacuum chamber-related spare parts | According to the manufacturer's manual cycle | OEM specifications for vacuum chamber-related spare parts |
| Cable and drag chain inspection | every six months | Insulation, shielding, and bending radius inspection of power and encoder lines, as well as wear of cables inside the drag chain, are the main causes of intermittent faults |
| Zero point and accuracy retest | Every year | Repeatability measured by dial gauges or laser trackers, drift trend digitization—accuracy degradation can be seen six months in advance |
| Control cabinet dust removal and fans | Every quarter | Filter cleaning, fan speed and noise checks, cabinet temperature recording; Dust environments shorten the cycle |

Common issues with this device
Is it easy to find spare parts for the SR500A-360/2.83?
Siasun Robotics: Spare parts channels for this generation are smooth; we have in-stock or short-cycle channels for standard parts such as drivers, power modules, batteries, and teach pendant components; For cleanroom models, it is recommended to configure consumables for cleanroom maintenance (tool cleaning, particle retesting) according to the annual maintenance contract.
With a nominal load of 360kg, how much can it actually handle?
The rated load is the static load limit of the flange surface. In actual selection, three factors must be considered: the self-weight of the end fixture (vacuum suction cup groups or grippers often account for 2–5kg), the inertia generated by the workpiece offload (checked according to the inertia ratio when the center of gravity deviates from the flange center), and the dynamic load during high-speed movement. The conventional engineering practice is to keep the "end + workpiece" within 70%–80% of the rated value to ensure cycle time and service life.
If the equipment's accuracy deteriorates after several years of use, how can it be restored?
According to the inspection order: first check whether the zero point is drifting (common after collision or battery depletion), then perform zero calibration; Check the reducer's return error (actual measurement of forward and reverse positioning deviation; if exceeded, disassemble or replace); Then check the installation base fastening and foundation settlement; Finally, trajectory compensation parameter restructuring. Most accuracy issues can be mostly restored after calibration and maintenance, so there is no need to rush into major repairs—we first release the inspection data before deciding on the plan.
Is the used SR500A-360/2.83 worth buying?
There is a large stock of clean and semiconductor equipment, and third-party maintenance requires cleanliness procedural capabilities—we have corresponding SOPs. Three essential items for second-hand procurement: comprehensive inspection reports (axial accuracy, driver status, insulation and battery), maintenance history and operating hours, controller generation, and software license integrity. Every used machine we sell comes with inspection records and a 12-month warranty, and we can also accept third-party inspections designated by customers.
