iER120-2400-PL model positioning and working condition adaptation

iER120-2400-PL This is an industrial robot model belonging to the Estun iER palletizing specialized robot, with a rated load of 120kg and a motion radius of 2400mm. 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 positioning large loads (120kg) is:Integrated palletizing, die-casting and part-picking, heavy handling and weldingCommon application processes for this model include palletizing, depalletizing, and handling. The long reach (2400mm) covers multiple stations and large pallets, reducing robot movement or coordination with ground track expansion. Foundation load-bearing and base fastening torque under heavy load conditions are essential items for installation acceptance; if the inertia ratio exceeds the limit, the cycle time will degrade significantly.

Engineering implications of the iER120-2400-PL specification parameters
ParametersEngineering interpretation and usage recommendations
Rated load capacity: 120kgIt 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: 2400mmDetermine 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: 4The four-axis structure has a clear speed advantage within the horizontal plane, while Z-direction travel and attitude freedom are limited, making it suitable for flat sorting and assembly
Protection rating: IP54Suitable 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 iER120-2400-PL comes with the Estun controller (self-developed movement 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.

Common issues with this device

Is it easy to find spare parts for iER120-2400-PL?

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 120kg, 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 iER120-2400-PL 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.
