ABB HAC025819-001 AC Servo Motor IRB7600-3 IRB6650S

ABB HAC025819-001 Servo Motor: Cut Downtime Before It Cuts Your Margin

Your IRB7600-3 axis just faulted. The teach pendant is throwing 38213 – Motor current error or 34301 – Joint 1 speed error. The line is cold. Every minute you spend waiting for parts is money leaving the building — and in automotive body shops or foundry cells running this robot, that number climbs fast. The HAC025819-001 is the OEM-specified AC brushless servo motor for the IRB7600-3 primary axis drive system. There is no functional substitute. We stock it in Xiamen and we ship it today.

The same urgency applies to the IRB6650S family. HAC062348-004 covers the /6.3 variant, HAC062346-004 the /4.3, and HAC062345-004 the /3 configuration. Four part numbers, one sourcing call. If you are reading this page at 2 AM with a production manager on the phone, send the email now — we respond around the clock.

Troubleshooting & Replacement Tips

Fault codes that point directly to this motor:

• 38213 – Motor current error (axis 1/2/3): Winding short or open circuit. Measure phase-to-phase resistance at the drive connector — should read within ±5% of OEM spec. Any open reading means the motor is gone.
• 34301 / 34302 – Joint speed error: Encoder signal dropout or corrupted absolute position data. Before condemning the motor, check the SMB (Serial Measurement Board, HAC026254-001) battery voltage. If the battery is dead, the encoder loses its reference and throws this fault even on a healthy motor.
• 50071 – Resolver fault: Intermittent on IRB6650S variants — often caused by a cracked encoder cable at the motor exit point, not the motor itself. Flex the cable while monitoring the fault log. If the fault clears and returns with cable movement, replace the cable first.

Step-by-step replacement procedure (field-condensed):

1. Set the robot to Calibration Position and record all axis resolver values from the FlexPendant before powering down. Photograph the screen.
2. Isolate and lock out the IRC5 cabinet. Discharge the drive capacitors — wait a minimum of 5 minutes after power-off before touching the motor connectors.
3. Disconnect the motor power cable (MP connector) and encoder cable (SMB connector) at the motor. Label both before removal.
4. Remove the motor mounting bolts (typically M8 × 4 on IRB7600-3 axis 1). Support the motor — it is heavier than it looks when you are working at an awkward angle inside the robot base.
5. Install the replacement HAC025819-001. Torque the mounting bolts to ABB specification (refer to the robot’s product manual, section Repair). Do not over-torque — the motor housing is aluminium.
6. Reconnect encoder cable first, then power cable. Verify connector locking tabs are fully seated — a half-seated SMB connector is the most common cause of a repeat fault after replacement.
7. Power up the IRC5. Navigate to ABB Menu → Calibration → Fine Calibration. Even if the absolute encoder retained its data, perform a fine calibration check on the replaced axis. Do not skip this step in a production environment.
8. Run the robot through its full working envelope at 10% speed before returning to auto mode. Monitor the axis current in the IRC5 event log for the first 30 minutes of operation.

Configuration notes: The HAC025819-001 is a direct OEM replacement — no DIP switch settings, no firmware flashing, no drive parameter changes required when replacing like-for-like on the same axis. If you are replacing a motor on a different axis than originally specified, contact ABB service or our technical team before proceeding, as axis-specific motor variants exist within the IRB7600 family.

Reliability in Harsh Conditions

ABB designed the IRB7600 and IRB6650S motor series for environments that destroy lesser components. The HAC025819-001 is validated for continuous operation in foundry extraction cells where ambient temperatures exceed 45 °C, airborne particulate levels are high, and the robot cycles 20+ hours per day. The motor’s sealed bearing arrangement and IP-rated connector system are not marketing language — they are the reason this motor outlasts the robot’s scheduled maintenance intervals in most installations.

Vibration resistance is equally critical. In press-tending applications, the robot base is exposed to low-frequency shock loads from adjacent stamping presses. The HAC025819-001’s rotor balancing and bearing preload are specified to handle this without developing the bearing noise that typically precedes encoder signal degradation in lesser motors. When you hear a faint grinding from the axis gearbox area, check the motor bearing before assuming gearbox wear — it is a faster and cheaper fix.

Humidity is the third axis of failure in coastal and tropical installations. The motor’s winding insulation class and conformal coating on the encoder PCB are rated for the condensing humidity cycles common in Southeast Asian and coastal European plants. Every unit we ship has been stored in climate-controlled conditions and inspected for moisture ingress before dispatch.

Global Express Logistics

Our dispatch warehouse is located in Xiamen, Fujian — one of China’s primary export hubs with direct access to DHL Express, FedEx International Priority, and UPS Worldwide Express gateways. For urgent orders confirmed before 15:00 CST, same-day dispatch is standard. Transit times to major industrial regions are typically 2–3 business days to Europe, 3–4 days to North America, and 1–2 days to Southeast Asia.

Every shipment is packed in anti-static foam with moisture-barrier inner bags and a shock-indicator label on the outer carton. The commercial invoice includes the correct HS code for servo motors (8501.52 or 8501.53 depending on output rating) and a detailed packing list to clear customs without delay. For customers in the EU, we can provide a EUR.1 movement certificate on request to support preferential duty treatment where applicable.

For bulk orders or repeat procurement contracts, we offer sea freight consolidation from Xiamen port with lead times of 18–25 days to European ports and 20–28 days to US East Coast ports. Contact us to discuss a standing purchase agreement with reserved stock allocation.
