Table of Contents Controller Specifications LC7R-K11A LC7R-K12A Model Regeneration method Heat exchange method based on resistance Regenerative resistance capacity 40W Regenerative operation voltage 180V 380V Regenerative absorption unit Regenerative voltage input mis-wiring protection Over current protection, Overheating protection (Normally closed, Radiator sensor OFF at 100C) Protective circuit To PLC,
A.7A0: Heat Sink Overheated (Detected when the heat sink temperature exceeds 100C.) Check the accumulated load ratio (Un009) to see the load during operation, and the regenerative load ratio (Un00A) to see the regenerative energy processing capacity. Excessive load or operation beyond the regenerative energy processing capacity. Reconsider the load and operating conditions.
