Beschreibung
Zusammenfassung:	The invention provides a three-dimensional garage frequency conversion and speed regulation control system with a brake monitoring function. The system comprises a power supply, a PLC control unit, a contactor, a frequency converter and a current-controlled relay detection feedback unit K4. According to the three-dimensional garage frequency conversion and speed regulation control system with the brake monitoring function, a single frequency converter is used for conducting open-loop control on multiple motors; meanwhile, a current controller is used for monitoring a working current of a target motor brake and feeding back monitoring information to the PLC control unit to conduct comprehensive judgment, and therefore synchronous action of the motor brake in the open-loop control process of the frequency converter is effectively guaranteed.
