Selema IPS2 Drive is a legacy industrial motor drive used in servo and CNC applications, typically featuring an integrated power supply, controller board, and I/O interface. Common failure modes for this class of units include degraded power regulation (brown‑out or over‑voltage), burnt capacitors on the main board, failed MOSFETs or driver ICs, and corrupted firmware or communication interfaces with PLCs. For first‑check diagnostics, verify that the drive’s input voltage is within spec and that output current limits are not being exceeded; inspect the PCB for visual signs of component damage such as bulging capacitors or burnt traces; and review any error codes displayed on the drive’s panel or transmitted to a connected PLC.[oss-gpt-20b]
