iER20B-2300-HI model positioning and working condition adaptation
iER20B-2300-HI This is an industrial robot model belonging to the Estun iER small to medium load series six-axis robots, with a rated load of 20kg and a motion radius of 2300mm. Estun's technical foundation is that of the top domestic brand, with self-developed core motion control technology, and after acquiring Germany's Cloos, its welding process capabilities have leapt forward; The control platform is the Estun Controller (self-developed movement control platform), and the program ecosystem consists of graphical programming + instruction scripting.
From the perspective of working condition adaptation, the typical use for medium-duty load (20kg) positioning is:Welding, machine tool wiring, medium-sized palletizing, and die-casting part removalCommon application processes for this model include handling, loading and unloading, grinding, assembly, and palletizing. The long reach (2300mm) 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 capacity: 20kg | 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: 2300mm | 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 |
| Protection rating: IP54 | Suitable for standard workshop environments; Dusty and moisture-prone workstations require additional protective kits or positive pressure protection |
| Controller: Estun Controller (self-developed platform for motion control) | 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 iER20B-2300-HI comes with the Estun controller (self-developed Motion Control Platform) controller, with a programming language and development environment of graphical programming + instruction scripts. 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 overcurrent/overload alarm | Driver overcurrent/overload alarm | Included as a mandatory inspection item for annual maintenance, with spare parts stocked in advance |
| Encoder feedback anomalies and cable interference | Encoder feedback anomalies and cable interference | Initial interpretation of alarm codes by reference with manuals, remote diagnosis allows for early positioning |
| The teach pendant system is lagging or crashing | Teach Pendant System Freezes or Crashes (Regular Restarts and Image Recovery) | Daily inspection coverage, with abnormal trends (abnormal noises/temperature rise/errors) recorded |
| IO module communication failure | IO module communication failure | Quarterly dust removal maintenance and cabinet temperature monitoring |
| Maintenance projects | Cycle recommendations | Key points |
|---|---|---|
| Regular backup of parameters and programs (dual USB drive + cloud storage) | Periodically | Regular backup of parameters and programs (dual USB drive + cloud storage) |
| Batteries should be replaced periodically | By cycle | Batteries should be replaced periodically |
| Reducer lubrication is managed by operating hours | By operating hours | Reducer lubrication is managed by operating hours |
| 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 iER20B-2300-HI?
Estun: 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; Parameters and programs are regularly backed up (USB drive + cloud dual copies). It is recommended to configure consumables according to the annual maintenance contract.
With a nominal load of 20kg, 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 iER20B-2300-HI worth buying?
Second-hand prices are low and circulation is increasing, suitable for budget-sensitive handling and palletizing tasks; Perform comprehensive inspections before purchasing. 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.
