PAL-260-3.1 Model positioning and working condition adaptation
PAL-260-3.1 This is an industrial robot model dedicated to Comau Rebel-S / PAL / PRESS robots, with a rated load of 260kg and a motion radius of 3100mm. Comau's technical foundation is based on Fiat heritage, with traditional strengths in automotive welding and heavy hauling, and the H5/Racer series stands out for its high-speed performance. The control platform is C5G / SMART5 and NJ series controllers, with a program ecosystem of PDL language + teach pendant.
From the perspective of working condition adaptation, typical applications for heavy-duty (260kg) positioning are:Vehicle body handling, large casting processing, building materials and heavy palletizing。 The extra-long reach (3100mm) is suitable for large workpieces and cross-line services, with attention to stiffness and vibration under large overhang postures. 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: 260kg | 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 |
| Movement radius: 3100mm | 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 |
| Number of axes: 6 | Six-axis all-posture capability, the preferred choice for complex trajectory and inclined surface operations |
| Controllers: C5G / SMART5 and NJ series controllers | 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 PAL-260-3.1 is a compatible C5G / SMART5 and NJ series controller, with a programming language and development environment of PDL + teach pendant. 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 |
|---|---|---|
| Controller board failure | Controller board failure (long spare parts cycle from older generations) | Included as a mandatory inspection item for annual maintenance, with spare parts stocked in advance |
| Encoder and feedback system abnormalities | Encoder and feedback system abnormalities | Initial interpretation of alarm codes by reference with manuals, remote diagnosis allows for early positioning |
| Aging of driver power devices | Aging of driver power devices | Daily inspection coverage, with abnormal trends (abnormal noises/temperature rise/errors) recorded |
| Teach pendant and cable loss | Teach pendant and cable loss | Quarterly dust removal maintenance and cabinet temperature monitoring |
| Maintenance projects | Cycle recommendations | Key points |
|---|---|---|
| Batteries should be replaced periodically | By cycle | Batteries should be replaced periodically |
| It is recommended to conduct a health assessment of the control system for existing automotive wiring equipment | According to the manufacturer's manual cycle | It is recommended to conduct a health assessment of the control system for existing automotive wiring equipment |
| Lubricate the reducer according to the manual | According to the manufacturer's manual cycle | Lubricate the reducer according to the manual |
| 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 PAL-260-3.1?
Comau This generation has smooth spare parts channels; we have in-stock or short-cycle channels for standard parts such as drivers, power modules, batteries, and teach pendant components; It is recommended to configure consumables for battery replacement periodically according to the annual maintenance contract.
With a nominal load of 260kg, 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 PAL-260-3.1 worth buying?
Many retired equipment at the automobile factory has stable salvage value of heavy machinery; For older controller projects, it is recommended to simultaneously evaluate upgrade plans. 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.
