Berger-Lahr WDP5-228 Stepper Drive

Berger‑Lahr WDP5‑228 is a high‑power stepper drive (1600 VA, 230–240 VAC) used to control three‑phase AC motors with precise speed and torque regulation. Common failures on this model include power supply degradation (input voltage ripple, overheating), internal MOSFET or IGBT burnout due to overcurrent or overload, and firmware corruption that can lock the drive into a fault state. First‑check diagnostics: verify line voltage and phase balance; inspect the drive’s heat sink and cooling fan for airflow and thermal damage; review the diagnostic LED or error code display for specific fault flags; and confirm that all input/output connections are secure and free of corrosion.[oss-gpt-20b] Post Comment
