Features:
- Wrist-axis role: ABB assigns the unit to IRB 4400 axis 6
- Four configuration groups: L30, 45 kg, 60 kg and spray are documented
- Technology boundary: Yaskawa and Elmo motor units are not compatible
3HAC021728-001 defines a Yaskawa wrist-drive assembly rather than a generic IRB 4400 motor.
Its official scope joins the motor and pinion at the mechanical interface to axis 6.
Correct technology identification, careful gear engagement and recalibration determine whether the service job can proceed safely.
Apter Power can review the IRB 4400 configuration, Yaskawa identity, complete 3HAC021728-001 label and quotation scope.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
- L30: axis 6 is included in the official technical note.
- 45 kg: the article is documented for this configuration.
- 60 kg: the same Yaskawa wrist motor is listed.
- Spray version: ABB includes the spray configuration in scope.
- Supplier identity: ABB identifies a Yaskawa motor.
- Technology boundary: the service manual rejects interchange with Elmo units.
- Release evidence: the installed motor label decides the permitted technology path.
- Drive interface: motor and gear are handled as one unit.
- Damage control: excessive force can damage pinion or gear-wheel contact.
- Sealing: the documented O-rings and gaskets return with the connection assembly.
- Closeout: recalibration precedes the first controlled run.
- IRB 4400 L30 wrist repair: service the documented Yaskawa axis-6 drive.
- IRB 4400 45 kg and 60 kg maintenance: renew the sixth-axis motor-and-pinion unit.
- IRB 4400 spray configuration: retain the official motor-technology boundary during wrist service.
