The elevator control system using D32 inverter has been put into operation for more than three years, and has achieved good economic and social benefits

• The control device operates reliably, has good environmental adaptability, can resist harsh environments such as oil pollution, dust and damp heat, and has a low failure rate;

• *Excellent current limiting characteristics, strong overload capacity, can effectively reduce frequency conversion overload, overcurrent protection, and maximize production continuity;

• *There is no "slip hook" phenomenon when the lifting weight is different when the load starts and stops;

• *Light load speed-up and loose rope detection functions meet customer requirements for improving production efficiency and safety.
