Epson N2 robot
Model introduction
Epson N2 Robot Reduces Installation Area by 40%, Lowering Footprint: As Epson's first foldable 6-axis robot, the N2 robot features a more compact structure than the C4 robot, allowing installation and operation within a workspace range of 600mm × 600mm consistent with manual work. Compared to traditional robots, it saves about 40% of space. Approximately 30% of cycle time is saved, easy to install and teach, and significantly increases productivity: the N2 robot combines the arched motion of the SCARA robot with the freedom of a 6-axis robot. Through a shear motion, the N2 robot's wrist can rotate 180°, reaching the target in the shortest distance, improving cycle time by about 30% compared to traditional models. Freely arranged layout with 360-degree continuous movement: compared to traditional models, the N2 robot reduces unnecessary movement of the first joint. It is especially practical in environments where equipment and mechanisms are installed in all directions of robot activity. The free layout allows the N2 robot to perform a variety of tasks in a confined space.

N2-A450SR model positioning and working condition adaptation
N2-A450SR Belongs to Epson N Series six-axis · The folding arm industrial robot model has a rated load of 2.5kg, a motion radius of 4000mm, and a repeatability of ±0.02mm. Epson's technological foundation is SCARA's global market leader: RS/GX/LS series with high speed and precision, SPEL+ development efficiency, and mature vision integration; The control platform is RC700-A, and the program ecosystem is SPEL+ language (BASIC style) + Vision Guide visual.
From the perspective of working condition adaptation, typical applications for small load (2.5kg) positioning are:High-speed sorting, precision assembly, dispensing coating, and inspection/pick-and-place processingCommon application processes for this model include handling and assembly. The extra-long boom (4000mm) is suitable for large workpieces and cross-line services, with attention to rigidity and vibration during large overhanging postures. ± 0.02mm repeatability is the standard level for six-axis industrial robots, covering the vast majority of welding operations, handling, palletizing, and loading and unloading operations. Although the load is light, it is recommended to keep the total weight of the end and workpiece within 70% of the rated value, leaving ample acceleration margin at high speeds.
| Parameters | Engineering interpretation and usage recommendations |
|---|---|
| Rated load capacity: 2.5kg | 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: 4000mm | 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: ±0.02mm | Repeatability ≠ absolute accuracy: Precision assembly requires external measurement closed-loop or visual guidance; Long-term accuracy trends rely on annual retest management |
| Main unit weight: 19kg | Installation base and foundation load-bearing check based on weight + dynamic load; Floor slab installation requires structural calculation, with heavy-duty models serving as independent foundations |
| Controller RC700-A | 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 RC700-A controller paired with the N2-A450SR features a programming language and development environment of SPEL+ (BASIC style) + Vision Guide visuals. 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 |
|---|---|---|
| SCARA synchronous belt tension attenuation and wear | SCARA Synchronous Belt Tension Attenuation and Wear (Main Cause of Precision Drift) | Included as a mandatory inspection item for annual maintenance, with spare parts stocked in advance |
| The encoder battery is depleted | Encoder battery depleted (loss of origin and calibration data) | Initial interpretation of alarm codes by reference with manuals, remote diagnosis allows for early positioning |
| Driver alarm | Driver alarm (high-speed overcurrent) | Daily inspection coverage, with abnormal trends (abnormal noises/temperature rise/errors) recorded |
| RC controller fan and power supply aging | RC controller fan and power supply aging | Quarterly dust removal maintenance and cabinet temperature monitoring |
| Maintenance projects | Cycle recommendations | Key points |
|---|---|---|
| Timing belt tension adjusted by periodic inspection (SCARA specific item) | By cycle | Timing belt tension adjusted by periodic inspection (SCARA specific item) |
| Annual battery replacement | Year | Battery replacement annually, calibration data backup |
| Guide rails and screw lubrication (LS/GX series) | According to the manufacturer's manual cycle | Guide rails and screw lubrication (LS/GX series) |
| 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 N2-A450SR?
Epson: The spare parts channel for this generation is smooth; 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 allocate consumables for periodic inspection and adjustment of synchronous belt tension (SCARA specific items) according to the annual maintenance contract.
With a nominal load of 2.5kg, 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 N2-A450SR worth buying?
SCARA has a large second-hand circulation and is the preferred choice for 3C and electronic assembly applications; Procurement focuses on checking for belt and guide rail wear. 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.
