Product Overview
The ABB GLB0201 is identified in industrial spare-parts references as a field weakening unit board used in ABB/BBC drive equipment. Its function is associated with the field-weakening section of a DC drive, where control of the motor’s field excitation supports operation above the base-speed range when the motor and drive are designed for that operating mode. The exact circuit design, electrical ratings, and drive compatibility of this particular board should be confirmed from the original equipment documentation.
GLB0201
This is a legacy component, so procurement should focus on matching the installed hardware rather than selecting a substitute by model-family resemblance. ABB’s lifecycle statement, issued in 2009, records the GLB0201 and GLB0501 drive products as obsolete from the beginning of 2010 and states that no replacement was available for the range at that time. Current availability and repair options should be confirmed separately.
Major Features and Advantages
- Field-weakening control function: Identified as a board associated with the field-weakening function in industrial DC drive equipment.
- Legacy equipment support: Can be relevant when maintaining an existing drive installation that still uses the original board.
- Model-specific replacement: The full GLB0201 designation helps distinguish the board from related drive components.
- Maintenance planning: Identification of the original part supports repair assessment and spare-parts planning for older systems.
- Compatibility verification: Connector layout, circuit revisions, drive model, and electrical ratings must be checked before installation.
Typical Applications
The ABB GLB0201 may be relevant to maintenance of legacy ABB/BBC DC drive systems that use the documented field-weakening board. The exact compatible drive models have not been independently verified, so confirm the installed drive’s model and original parts list before ordering.
Installation and Maintenance
- Record the drive model, serial number, and complete board markings.
- Compare connector positions, mounting points, and revision identifiers with the installed board.
- Follow the drive manufacturer’s isolation and stored-energy discharge procedures before servicing.
- Have a qualified drive technician inspect the board and associated field-excitation circuitry.
- Perform commissioning checks according to the applicable drive manual before returning equipment to service.
Product Assurance and Procurement Notes
Because GLB0201 is an obsolete part, request clear photographs of the actual board, its labels, and its connectors. Confirm whether the unit is new old stock, used, or refurbished, and obtain written details of any functional testing and warranty.
Do not assume that another GLB-series board is interchangeable. ABB’s published lifecycle statement reports no designated replacement for this product range, so any proposed alternative requires an engineering compatibility assessment.
