Frequency converter speed regulating circuit with main speed setting box and linkage setting operating box
Source: InternetPublisher:萌面大虾 Updated: 2019/09/30
As shown in the figure, FR-FG is the main speed setting device, and FR-AL is the linkage setting operation box. The figure shows an NFB that can be connected to multiple FR-AL linkage setting boxes and multiple frequency converters to achieve synchronous operation of several three-phase motors, and is also suitable for simultaneous acceleration and deceleration (speed change). The main speed setting is set by the potentiometer RP. Latest Control Circuits Circuits
