ABB 3HAC17335-1 Replacement for IRB4400 Series

Product Overview

ABB 3HAC17335-1 Replacement for IRB4400 Series: Seamless Transition & Legacy System Compatibility

The ABB 3HAC17335-1 is a precision AC servo motor engineered for the IRB4400 industrial robot series. As ABB progressively phases out legacy drive and motion components, facilities running IRB4400 cells face increasing pressure to source reliable, specification-matched replacements before production continuity is compromised. This listing provides a verified, tested replacement unit for the 3HAC17335-1 that supports a smooth, low-risk migration from aging or end-of-life motor assemblies — without requiring mechanical redesign, rewiring overhauls, or controller reprogramming.

Whether your maintenance team is responding to an unplanned motor failure, executing a scheduled preventive replacement, or upgrading a multi-axis robot cell to extend its operational lifespan, the 3HAC17335-1 replacement offered here is pre-tested, fully documented, and ready to ship from bonded stock in Xiamen, China.

Seamless Upgrade Solutions

A successful IRB4400 motor replacement rarely involves a single component in isolation. In practice, field engineers replacing the 3HAC17335-1 often simultaneously inspect or replace adjacent components to ensure the entire axis assembly is restored to full operational integrity. The ABB SMB (Serial Measurement Board), which interfaces directly with the motor encoder, should be verified for firmware compatibility and connector condition before recommissioning — a degraded SMB can cause axis calibration errors even with a new motor installed.

The ABB DSQC508 or DSQC679 teach pendant, used for manual jogging and axis calibration during motor replacement, must be confirmed operational before the technician begins the commissioning sequence. Similarly, the ABB DSQC661 or DSQC662 axis computer board within the IRC5 controller cabinet governs the drive signals sent to the 3HAC17335-1 motor; any fault history stored in the axis computer should be cleared and re-evaluated post-replacement.

For facilities running older S4C+ controllers rather than IRC5, the ABB DSQC346 drive unit or equivalent S4C+ axis drive module must be inspected for compatibility with the replacement motor’s encoder signal format. In some S4C+ installations, the ABB 3HAC025338-001 or 3HAC14550-2 cable harness connecting the motor to the drive unit may show wear after years of continuous robot operation and should be replaced concurrently to prevent intermittent faults post-commissioning.

Where the IRB4400 cell is integrated into a broader production line managed by an ABB AC500 PLC or a third-party Siemens S7-300/S7-400 controller via DeviceNet or PROFIBUS-DP, the fieldbus node address and I/O mapping for the robot cell should be documented before the motor swap to ensure the PLC program does not require modification. In most cases, the motor replacement is transparent to the PLC layer — the robot controller handles all axis-level communication internally.

Facilities upgrading multiple axes simultaneously may also require the ABB 3HAC17484-1 or equivalent counterpart motor for adjacent axes, as well as updated axis calibration data loaded via the ABB RobotStudio offline programming environment. Keeping a spare ABB DSQC508 measurement board and a set of axis-specific calibration pendants on hand significantly reduces recommissioning time during multi-axis overhauls.

Retrofit Guidance FAQ

Q: Does replacing the 3HAC17335-1 require changes to the IRC5 controller configuration?
A: In most cases, no. The IRC5 controller stores axis parameters in its system configuration files. As long as the replacement motor matches the original encoder type and wiring pinout, the controller will recognize the motor without parameter changes. A standard axis calibration (fine calibration) is recommended after installation to restore positional accuracy.

Q: Is the replacement compatible with S4C+ controllers as well as IRC5?
A: Yes. The 3HAC17335-1 was used across both S4C+ and early IRC5 IRB4400 installations. The replacement unit maintains the same encoder interface and connector standard, making it compatible with both controller generations. Verify the drive unit firmware version in S4C+ installations for optimal compatibility.

Q: Will I need to re-run the robot’s full calibration after motor replacement?
A: A fine calibration of the affected axis is always recommended after any motor replacement. Full system calibration is only required if the robot base or tool center point (TCP) has been disturbed. Use the ABB calibration pendulum or reference marks on the robot arm for axis-level fine calibration.

Q: What is the physical installation procedure?
A: The 3HAC17335-1 is a bolted flange motor. Disconnect power, lock out the axis, remove the motor connector and encoder cable, unbolt the motor from the axis housing, install the replacement unit, reconnect cables in reverse order, and perform fine calibration. No special tooling beyond standard ABB robot maintenance tools is required.

Q: Can this replacement be used in a robot cell with a Siemens or Rockwell PLC supervising the IRC5?
A: Yes. The PLC communicates with the IRC5 controller via fieldbus (DeviceNet, PROFIBUS, EtherNet/IP, or similar). The motor replacement is entirely internal to the robot controller and is invisible to the supervising PLC. No PLC program changes are required.

Q: What communication protocols does the IRB4400 support for integration?
A: The IRB4400 with IRC5 supports DeviceNet, PROFIBUS-DP, EtherNet/IP, and Interbus via optional fieldbus adapter boards (DSQC series). The motor replacement does not affect fieldbus configuration.

Warranty Assurance

Every 3HAC17335-1 replacement unit shipped by TOPNLMS is covered by a 12-month warranty from the date of delivery. Prior to shipment, each unit undergoes a multi-point outgoing inspection including visual examination, connector integrity check, encoder signal verification, and insulation resistance testing. Units that do not pass inspection are not shipped.

In the event of a warranty claim, TOPNLMS provides a replacement unit or full refund within the warranty period. Our technical support team is available to assist with installation questions, compatibility verification, and commissioning guidance. We maintain bonded stock of critical ABB IRB series components to support rapid dispatch — most orders ship within 1–3 business days from our Xiamen warehouse.

For urgent production-down situations, expedited shipping options are available. Contact our team directly to discuss priority fulfillment and air freight arrangements to minimize your facility’s downtime.
