ABB AGBB-01C REV.B Replacement for ACS800/ACS600

Product Overview

ABB AGBB-01C REV.B Replacement for ACS800/ACS600: Seamless Transition & Legacy Drive Upgrade

The ABB AGBB-01C REV.B is a precision IGBT Gate Driver Board engineered for ABB’s ACS800 and ACS600 series variable frequency drives. As ABB progressively phases out legacy drive components, many facilities running ACS800-01, ACS800-04, ACS800-07, and ACS600 series drives face the critical challenge of sourcing a verified, drop-in replacement that preserves existing wiring, firmware compatibility, and control cabinet layout. This listing provides exactly that — a tested, ready-to-ship AGBB-01C REV.B board that enables a smooth, low-downtime transition without requiring full drive replacement or panel redesign.

Whether your plant is operating a legacy ACS600 installed in the early 2000s or a mid-generation ACS800 that has reached end-of-component-life, the AGBB-01C REV.B restores full IGBT switching function, gate pulse integrity, and fault protection logic — all without modifying the existing power stage or control wiring harness.

Seamless Upgrade Solutions

A successful ACS800 or ACS600 gate driver replacement rarely happens in isolation. In most retrofit and modernization projects, the AGBB-01C REV.B is installed alongside a broader set of drive components to ensure the entire power conversion chain is restored to specification. During commissioning, engineers typically inspect and often replace the AINT-01C auxiliary interface board, which supplies the isolated gate driver power rails and handles the DDCS fiber-optic communication link between the control unit and the power module. If the AINT board shows signs of capacitor aging or optical port degradation, replacing it concurrently with the AGBB-01C REV.B eliminates the risk of a secondary fault within weeks of the initial repair.

The APOW-01C auxiliary power supply board is another component that frequently requires attention during ACS800 refurbishment. It provides the ±15 VDC rails that the gate driver board depends on; a marginal APOW board can cause intermittent gate pulse failures that are difficult to diagnose without replacing both boards simultaneously. Similarly, the ACON-01C control board — which manages speed reference, I/O signal processing, and fieldbus communication — should be verified for firmware version compatibility when upgrading from an early ACS800 revision to ensure the drive’s parameter set remains intact after the hardware swap.

For plants integrating the repaired ACS800 into a Profibus DP or PROFINET network, the RPBA-01 Profibus adapter module or the RETA-01 Ethernet adapter may need to be re-seated or reconfigured following the gate driver replacement, particularly if the drive was powered down for an extended period and the adapter’s node address or baud rate settings were lost. In ACS600 installations, the equivalent NAMC-11 or NAMC-51 motor control boards serve a similar role and should be inspected for corrosion or connector wear during the same maintenance window.

Control cabinet space is rarely a concern with this replacement — the AGBB-01C REV.B shares the identical PCB footprint and connector layout as all previous revisions, so no bracket modification, cable extension, or DIN rail repositioning is required. For facilities that also operate ACS550 or ACS355 drives in adjacent panels, spare IGBT driver boards for those platforms should be sourced separately, as the gate driver architecture differs between product families. However, the commissioning workflow — power isolation, ESD handling, fiber-optic reconnection, and parameter verification via DriveWindow or DriveComposer — is consistent across the ACS800 and ACS600 families, allowing the same field engineer to handle multiple drive types in a single site visit.

Where the existing installation uses an RDCO-01C or RDCO-03C DDCS communication board for multi-drive master/follower configurations, the AGBB-01C REV.B replacement does not affect the DDCS topology or the fiber ring wiring. The follower drive will resume normal operation once the gate driver board is seated and the drive is re-enabled from the master ACS800 control unit, without requiring any changes to the DDCS node addresses or the master’s parameter group 70 settings.

Retrofit Guidance FAQ

Q: Will the AGBB-01C REV.B work with my existing ACS800 wiring without modification?
A: Yes. The REV.B board uses the same connector pinout, fiber-optic port positions, and PCB mounting holes as all previous AGBB-01C revisions. No wiring changes are required. Simply follow ABB’s standard field replacement procedure: isolate power, discharge DC bus, remove the old board with ESD precautions, seat the new board, and reconnect the fiber-optic cables.

Q: Do I need to re-flash or reconfigure the drive after replacing the gate driver board?
A: No firmware or parameter changes are required for the gate driver board itself. The AGBB-01C REV.B does not store drive parameters. All application parameters remain in the ACON or NAMC control board. However, we recommend verifying the drive’s fault history and running a short no-load test after installation to confirm gate pulse symmetry across all six IGBT phases.

Q: Is this board compatible with both ACS800 and ACS600 series drives?
A: The AGBB-01C REV.B is primarily designed for ACS800-01, ACS800-04, and ACS800-07 power modules. Compatibility with specific ACS600 variants depends on the power module frame size. Please provide your drive’s full type code (e.g., ACS800-01-0016-3) when inquiring, and our technical team will confirm compatibility before shipment.

Q: What communication protocols are supported after the replacement?
A: The gate driver board operates below the communication layer — it handles IGBT switching signals only. All fieldbus protocols (Profibus DP via RPBA-01, Modbus RTU via RMBA-01, DeviceNet via RDNA-01, or Ethernet/IP via RETA-01) continue to function through their respective adapter modules without any reconfiguration.

Q: How do I verify the replacement was successful before returning the drive to service?
A: After installation, power up the drive in local control mode with the motor disconnected. Use DriveWindow Light or DriveComposer to monitor the gate driver status signals and confirm no IGBT fault codes (e.g., fault 2310 or 2340) are present. Then perform a short no-load run at low speed to verify current symmetry across all output phases before reconnecting the load.

Warranty Assurance

Every ABB AGBB-01C REV.B shipped by TOPNLMS is covered by a 12-month warranty from the date of delivery. Prior to shipment, each board undergoes a multi-point outgoing inspection that includes visual examination for PCB damage, connector integrity verification, and functional testing of the gate driver signal paths where test equipment permits. Boards that do not pass inspection are not shipped.

If a warranty claim arises within the 12-month coverage period, TOPNLMS will provide a replacement unit or issue a refund, subject to inspection of the returned board. Our after-sales response target is within 24 business hours for warranty inquiries. We maintain stock of AGBB-01C REV.B boards to support rapid replacement dispatch, minimizing the impact of a warranty event on your production schedule.

For procurement teams requiring documentation, we can provide a packing list, commercial invoice, and certificate of conformity upon request. Boards are shipped with ESD-protective packaging and foam cushioning to prevent transit damage. Standard lead time from order confirmation to dispatch is 1–3 business days for in-stock units, with express international shipping available to most destinations.
