Epson industrial robot option pressure sensor system
Model introduction
Epson Industrial Robot Option Pressure Sensor System Main Features of Epson Pressure Sensor: High rigidity and high sensitivity function enable detection of small forces and excellent response. The robust and durable construction limits sensor deformation and prevents loss of sensitivity and responsiveness due to sensors operating in uncertain positions, making both sensors and workpieces less prone to damage. High rigidity: The rated load in the Fx, Fy, and Fz directions is 250N, and the rated load torque in the Tx, Ty, and Tz directions is 18Nm; The high rigidity of pressure sensors means that even under enormous forces, deformation can be minimized as much as possible. High rigidity provides good resistance to torque and torque. High sensitivity: achieves low noise level of 0.035N and high resolution of 0.1N (XYZ directional decomposition); Its excellent high resolution allows forces to be detected and responded to well

Force Sensor model positioning and working condition adaptation
Force Sensor An industrial robot model from Epson Vision and Automation Options, rated at 250kg. 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 / RC-A101 (older models RC620 and earlier), and the program ecosystem is SPEL+ language (BASIC style) + Vision Guide.
From the perspective of working condition adaptation, the typical use for heavy-duty (250kg) positioning is:Vehicle body handling, large casting processing, building materials and heavy palletizingCommon application processes for this model include handling and assembly. 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: 250kg | 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 |
| Protection rating: IP67 | Resistant to dust and washing environments (suitable for food and beverage, casting and grinding stations) |
| Main unit weight: 460kg | 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 / RC-A101 (older models RC620 and earlier) | 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 Force Sensor supports the RC700 / RC-A101 controllers (older models RC620 and earlier), with SPEL+ programming languages (BASIC style) + Vision Guide for the 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 |
|---|---|---|
| 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 Force Sensor spare parts?
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 250kg, 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 a used Force Sensor 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.
