Delem DM 602 is a servo drive module used in industrial motion control systems, typically mounted on machine tool or press brake panels. Common failure points for this class of units include power supply voltage spikes damaging the driver ICs, overheating of the motor controller board due to inadequate cooling, and degradation of the input/output relays or opto‑isolators that handle drive signals. First‑check diagnostics: verify the 24 V/48 V DC rail is within spec and stable; inspect for burn marks, cracked solder joints, or swollen electrolytic capacitors on the board; and review any error codes displayed on the host controller or panel to identify fault flags such as “DRV_OVR” or “IO_ERR.”[oss-gpt-20b]
