When using an inverter, a leakage maintainer must not be used. This is a major principle of the use of frequency converters. Some users choose the corresponding leakage maintainer for the inverter when using the inverter. *The result is: the inverter moves together, the leakage maintainer acts, and the system foundation cannot be ...

The selection of the inverter should be considered according to the type of controlled object, speed regulation scale, static speed accuracy, starting torque, etc., so that it is easy to use and economical together with the satisfaction of process and production requirements. 1. Inverter and the motor to be operated (1) The number of poles of the motor. General motor ...

The PLC should be kept away from strong disturbance sources such as electric welding machines, high-power silicon rectifier equipment and large-scale power equipment, and cannot be installed in the same switch cabinet as high-voltage electrical appliances. Power line, control line and PLC power line and I/O line should be separated from the wiring, barrier transformer and PLC and I/O should be selected ...
