Mity VEO491A is a high‑speed industrial servo drive designed for CNC and motion control applications, typically powered from a 24 V DC supply with integrated protection against overvoltage and overload conditions. Common failure points include damaged power MOSFETs or IGBTs due to voltage spikes, degraded gate driver ICs causing erratic motor response, and capacitor failures in the input filtering network leading to noise‑induced errors; overheating of the heat sink can also trigger thermal shutdowns. Initial checks should verify that the DC supply is within spec (≤24 V), inspect the power module for burn marks or swollen capacitors, and confirm that all ground connections are secure; then review any fault codes displayed on the drive’s panel or via its communication interface to pinpoint the specific error source.[oss-gpt-20b]
