Lenze 2002.2B 2002 LEA Drive Control PCB Module
Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 2002.2B is a drive control PCB module designed for central analog signal conditioning and regulation within Lenze 2002 model units and the broader LEA product family. Serving as a dedicated control card in standard industrial power converters, this board processes analog drive setpoints and voltage feedback signals required for stable variable-speed motor control. Identity features of the module include an integrated highly stabilized ±15V DC power pack providing 2x60 mA of potential-free power, a built-in bipolar set-value integrator for smooth acceleration ramps, and precision voltage follower circuitry.
When commissioning a replacement 2002.2B card within Lenze LEA series power converters or 2000 series drive assemblies, technicians must ensure accurate physical seating into the rack and correct terminal connections for analog setpoint inputs and feedback lines. Replacing this module requires verifying that the potential-free power output lines are isolated properly to prevent ground loops and electrical noise interference across control circuits. Because analog drive control cards depend on precise signal alignment, installing a spare unit may require setting analog potentiometers or matching baseline drive setpoints to mirror the original installation. ABC Industrial Parts can assist maintenance teams with bench testing and verifying control card functionality prior to final installation.
Troubleshooting drive instabilities or setpoint losses in legacy converter equipment involves initial power and circuit checks on the control card. Verification of the ±15V DC potential-free supply voltages and inspection of incoming reference signals help confirm whether the issue stems from external wiring or the internal card circuitry. Because component-level faults within analog signal conditioning paths and power regulation stages are not field-serviceable, replacing a suspect module or utilizing an exchange service through ABC Industrial Parts provides a rapid route back to operational status while avoiding full system retrofits.

Replacement and Spare Part Considerations
The Lenze 2002.2B functions as a direct drop-in replacement card for legacy Lenze LEA series standard power converters and 2000 series drive assemblies. It directly replaces equivalent board designations including part numbers 00327511 and 35.471--E. When swapping out a failed control PCB, verifying hardware cross-references ensures seamless mechanical and electrical integration into the existing converter chassis.
Before restoring power to a newly installed spare board, maintenance personnel should inspect terminal blocks, setpoint input wiring, and power supply isolation. Confirming that external noise sources are mitigated and ground loops are prevented ensures that the ±15V DC potential-free power pack operates within specified parameters to deliver stable control signals.
Utilizing direct replacements allows factory automation, packaging machinery, material handling, and textile processing facilities to extend the service life of existing LEA drive infrastructure without undertaking costly control retrofits or panel redesigns.
