Chapter 6 Crane specialinverter faults and troubleshooting 41

◆

Advice for improve safety:

1) 1) The circuit design must ensure fault safety. Ensure that any external safety circuit, inverter, brake,
motor or any safety device loses power, short-circuit, fault, etc., and can ensure safety. Parking and no
operation;
2) The selection of the inverter and motor must be sufficient to leave sufficient margin;
3) External mechanical auxiliary contacts also can be connected in series into the safety circuit, using
the normally closed contact;
4) Regularly check the brake if OK and the wear of brake pads ;
5) Regularly check the perimeter security equipment if intact and if working properly;
6) Without the rigorous verification not recommend run in the constant power region.
