The Lenze 532_E.1B is a 530‑series speed controller designed for 220 VAC input and dual output stages (≈2 A/180 V and 0.3 A/200 V) used in servo drive or motor control applications. Common failure points for this model include burned capacitors on the power stage, damaged MOSFETs or IGBT modules, and overheating of the heat‑sink due to inadequate ventilation; these often manifest as over‑current protection trips or “output not available” error codes. Initial checks should verify that the input voltage is within spec, inspect the output terminals for visible damage or burn marks, and review the controller’s diagnostic LEDs or serial log for fault codes related to power supply or temperature limits. If no obvious hardware faults are found, test the internal power‑stage components with a multimeter and confirm proper cooling airflow before proceeding to firmware reflash or component replacement.[oss-gpt-20b]
