NTJ10 model positioning and working condition adaptation
NTJ10 This is an industrial robot model belonging to Kawasaki's wafer handling robot NTJ/TTJ/NTH/NX series, with load parameters based on the official manual and a movement radius of 1067.2mm. Kawasaki's technical foundation is strong AS language capabilities and deep accumulation in semiconductor cleanliness and welding applications; The control platform is F series (partial) / E series, and the program ecosystem is AS language + teach pendant.
From the perspective of operating condition adaptation, typical applications for positioning this load level are:Handling, assembly, and general automationCommon application processes for this model include wafer handling. The medium reach (1067.2mm) meets the needs of conventional workstations, offering flexible single-station layout. Specific load parameters are subject to the nameplate and official manual.
| Parameters | Engineering interpretation and usage recommendations |
|---|---|
| Radius of motion: 1067.2mm | 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 |
| Controllers F Series (partial) / E Series | 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 NTJ10 comes with F-series (partial) and E-series controllers, with an AS language and development environment of AS + teach pendant. 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 |
|---|---|---|
| 1FB/2FB board failure | 1FB/2FB board fault (driver control board aging) | Included as a mandatory inspection item for annual maintenance, with spare parts stocked in advance |
| The encoder battery is depleted, causing the origin to be lost | The encoder battery is depleted, causing the origin to be lost | Initial interpretation of alarm codes by reference with manuals, remote diagnosis allows for early positioning |
| The teach pendant's LCD and buttons are aging | The teach pendant's LCD and buttons are aging | Daily inspection coverage, with abnormal trends (abnormal noises/temperature rise/errors) recorded |
| Overcurrent alarm in the driver unit | Overcurrent alarm in the drive unit (motor or load abnormality) | Quarterly dust removal maintenance and cabinet temperature monitoring |
| Maintenance projects | Cycle recommendations | Key points |
|---|---|---|
| The battery is replaced annually | Every year | The battery should be replaced annually, and the original calibration should be performed after replacement |

| Spare parts for boards and cards are recommended for key customers with in-house redundancy | According to the manufacturer's manual cycle | Spare parts for boards and cards are recommended for key customers with in-house redundancy |
| 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 |
Henghuan's service capabilities for NTJ10
This site is a third-party robotics technology service provider. The eight major services supported by the NTJ10 are as follows (sorted by service frequency of each model):
- Maintenance and repair: For NTJ10's on-site diagnosis, board-level maintenance, and annual maintenance contract—annual battery replacement, we follow SOPs and respond to Sichuan-Chongqing on the same day.

Common issues with this device
Is it easy to find NTJ10 spare parts?
Kawasaki: 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 replace consumables for batteries annually according to the annual maintenance contract.
With a nominal load of X kg, how much weight 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 NTJ10 worth buying?
Second-hand circulation is moderate, and we have accumulated experience in E/F series materials and board-level repair channels. 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.
