The MITY VEO‑04EF is a compact servo drive/controller designed for precise motion control in industrial automation and robotics, offering both position and torque regulation. Common failure points for this class of drives include power supply degradation (over‑voltage or ripple), overheating of the MOSFETs/IGBTs, loss of communication with the host PLC, and failure of the internal EEPROM or firmware corruption. Initial troubleshooting should verify that the input voltage is within spec and free of spikes, inspect the drive for excessive heat or burnt components, confirm all I/O connections (digital inputs, analog outputs, and serial links) are secure, and review any diagnostic error codes displayed on the panel or logged by the host system.[oss-gpt-20b]
