Universal inverter mechanical brake control
Universal inverter mechanical brake control
From the start of potential energy load inverter application field, the mechanical brake control function is become the important thing which need to maintain and design. Since the general inverter itself has certain limitations, resulting in the shortage of function of resource which can be used, in the actual application of general inverter, generally have the following several control methods:
1.The operation signal and the fault output of general inverter compose the mechanical braking control signal to control the mechanical;
2.Can define the fault output signal and the switching output signal of general inverter to form a mechanical brake control signal;
3.The operation signal of general inverter,fault output signal, the switch output signal, the current analog signal input to the inverter PLC,using programming control function of PLC to design control conditions ofmechanical brake,and using PLC output signal to control the mechanical brake.
The three methods above, the former two kinds general apply in the requirements of the system which is relatively simple control, third control methods used in more complex system, the control precision requirements are relatively high, but need to apply in PLC system.
