ER50-2100 model positioning and working condition adaptation
ER50-2100 This is the industrial robot model of the EFT ER with a load of six-axis robots, rated at 50kg, and a motion radius of 2146mm. EFORT's technical foundation is the acquisition of Italy's EVOLUT (integrated) and WFC (woodworking), with mature spraying and general handling process packages; The control platform is an M-type control cabinet, and the program ecosystem consists of graphical programming + process package calling.
From the perspective of working condition adaptation, typical applications for medium-duty loads (50kg) positioning are:Welding, machine tool wiring, medium-sized palletizing, and die-casting part removalCommon application processes for this model include arc welding, handling, loading and unloading, gluing, and grinding. The long reach (2146mm) covers multiple stations and large pallets, reducing robot movement or coordination with ground track expansion. This level is the main stage for welding and loading; when selecting a positioner or dual stations, pay attention to the total cycle time and interference zone planning.
| Parameters | Engineering interpretation and usage recommendations |
|---|---|
| Rated load: 50kg | 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 motion: 2146mm | 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 |
| Controller: M-type control cabinet | 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 M-type control cabinet controller accompanying the ER50-2100 features a programming language and development environment of graphical programming + process package calls. 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 |
|---|---|---|
| Driver alarm and encoder abnormality | Driver alarm and encoder abnormality | Included as a mandatory inspection item for annual maintenance, with spare parts stocked in advance |
| Explosion-proof parts of spraying machine models are aging | Explosion-proof parts of spraying models aged (sealing and grounding) | Initial interpretation of alarm codes by reference with manuals, remote diagnosis allows for early positioning |
| The teach pendant malfunctioned | The teach pendant malfunctioned | Daily inspection coverage, with abnormal trends (abnormal noises/temperature rise/errors) recorded |
| Communication between IO and bus is abnormal | Communication between IO and bus is abnormal | Quarterly dust removal maintenance and cabinet temperature monitoring |
| Maintenance projects | Cycle recommendations | Key points |
|---|---|---|
| Spray explosion-proof models undergo annual inspection according to explosion-proof regulations (grounding, sealing, certification effectiveness). | According to the manufacturer's manual cycle | Spray explosion-proof models undergo annual inspection according to explosion-proof regulations (grounding, sealing, certification effectiveness). |

Henghuan's service capabilities for ER50-2100
This site is a third-party robotics technology service provider. The ER50-2100 supports eight major business services as follows (sorted by service frequency of each model):
- Maintenance and repair: For the ER50-2100 on-site diagnosis, board-level maintenance, and annual maintenance contract—spray explosion-proof models are inspected according to explosion-proof regulations (grounding, sealing, certification effectiveness), and other brand-exclusive items are carried out according to SOP, with same-day response from Sichuan and Chongqing.
- Used & in-stock robot sales: Second-hand circulation is increasing, and the procurement of spray painting models requires verification of explosion-proof certification documents; Inventory ER50-2100 or equivalent models come with a full-function test report and a 12-month warranty.
- Sales of new industrial robots: When adding new production lines or replacing batches, we conduct cross-brand selection comparisons based on process requirements (including models of the same class as EFORT), and provide configuration and pricing plans.
- Applied technology services: Process programming, trajectory optimization, tap time potential, and formula management for ER50-2100, with targeted commissioning for arc welding, handling and loading, gluing, and grinding conditions.

Common issues with this device
Is it easy to find spare parts for the ER50-2100?
EFORT: 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; For sprayed explosion-proof models, it is recommended to configure consumables for annual inspection (grounding, sealing, certification effectiveness) according to explosion-proof regulations according to the annual maintenance contract.
With a nominal load of 50kg, 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 ER50-2100 worth buying?
With the increasing circulation of second-hand products, it is necessary to verify explosion-proof certification documents when purchasing spray painting models. 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.
