Configured for Axis 2 mechanical drive operation in the ABB IRB 2400 robot, the ABB 3HAC021350-001 (3HAC021350-001 Motor M27 Type B) provides motor torque through the integrated piston/mechanical interface and uses absolute multi-turn feedback for robot axis position control.

Part Identification

ABB documentation identifies 3HAC021350-001 as a Motor, Axis 2 for the IRB 2400. The documented configuration specifies Yaskawa manufacture and ABB Orange color. ABB also lists 3HAC021350-003 as another Axis 2 motor configuration and states that the different motor types are not interchangeable.

The supplied product description identifies the unit as MOTOR M27 TYPE B W/PISTON. Third-party technical listings independently associate the part with the IRB 2400 Axis 2 motor assembly.

Hardware Data

ABB Robot Drive Interface

The 3HAC021350-001 is an Axis 2 motor rather than a general-purpose PLC motor. ABB's IRB 2400 service documentation places this part in the Axis 2 motor replacement procedure and identifies the corresponding robot-specific service equipment.

The multi-turn absolute encoder provides position feedback to the robot servo control system. The encoder interface must remain matched to the installed ABB controller and motor-drive configuration.

ABB specifically warns that the different Axis 2 motor variants are not compatible. Motor replacement therefore requires matching the exact spare-part number and robot configuration rather than selecting only by rated power.

Mechanical Drive Characteristics

The M27 Type B designation identifies the mechanical motor configuration used by the robot assembly. The supplied description specifies the motor with piston.

The motor is documented as an Axis 2 component for IRB 2400 robots. The corresponding ABB service procedure requires mechanical inspection and replacement of associated sealing components during motor service.

The motor should be installed without applying uncontrolled axial or radial loading to the shaft or piston mechanism. Mechanical alignment must be verified before servo power is restored.

Feedback and Control

The multi-turn absolute encoder provides position information to the robot servo system.

The feedback circuit should be connected only to the controller interface specified for the corresponding IRB 2400 configuration. Generic encoder substitution should not be performed without confirming electrical protocol, connector configuration, and controller compatibility.

ABB's service documentation also specifies a dedicated 24 VDC supply, with a maximum of 1.5 A, for releasing the robot motor brake during the documented replacement procedure.

Axis 2 Installation Procedure

Mechanical Preparation

• Disconnect all electrical power before motor removal.
• Isolate hydraulic and pneumatic supplies where applicable to the robot installation.
• Verify that the replacement part number is 3HAC021350-001.
• Confirm that the motor configuration matches the robot's existing Axis 2 assembly.
• Inspect the piston and mechanical coupling for contamination or damage.
• Inspect the mounting surface before installing the replacement motor.

Electrical Preparation

• Verify the 230 V AC motor supply circuit against the installed robot drive.
• Verify the absolute encoder connection before energizing the system.
• Keep motor power conductors separated from low-level feedback wiring where practical.
• Maintain protective earth continuity.
• Do not apply servo power while the feedback connector is partially engaged.

Brake Release and Calibration

• ABB specifies 24 VDC, maximum 1.5 A, for releasing the brake during the documented motor replacement procedure.
• Complete the mechanical installation before brake release.
• Perform the applicable ABB robot calibration procedure after motor replacement.
• Verify Axis 2 position feedback before normal robot motion.
• Perform controlled low-speed movement before returning the robot to automatic operation.

Frequently Asked Questions

• What robot axis uses 3HAC021350-001?

  ABB identifies 3HAC021350-001 as the Axis 2 motor for the IRB 2400 robot.

• What motor type is 3HAC021350-001?

  The supplied description identifies it as an M27 Type B motor with piston. ABB service data identifies it as an Axis 2 motor.

• Is the motor compatible with other Axis 2 motor versions?

  ABB states that the different motor variants are not compatible. The exact spare-part number must therefore be matched to the robot configuration.

• What is the rated motor power?

  The supplied specification gives a rated power of 1.1 kW at a rated speed of 1450 min-1.

• What feedback device is fitted?

  The supplied product data specifies a multi-turn absolute encoder. The encoder interface must match the installed ABB controller and drive.

• What temperature range is specified?

  The supplied product data specifies an operating range from -15 deg C to +55 deg C. No additional derating curve was provided.

• What supply is used to release the motor brake?

  ABB's service procedure specifies 24 VDC with a maximum current of 1.5 A for releasing the brake during motor replacement.

• Are sealing components included with the motor?

  ABB lists O-ring 21522012-434 and gasket 3HAB3676-1 as separate service items. They should not be assumed to be included unless the supplied assembly documentation states otherwise.
