UFC921A101 3BHE024855R0101 ABB inverter interface module
Frequency converter interface module plays an important role in the frequency converter, its main functions include:
1: Input interface: receive external control signals, such as control box, PLC, etc., for start and stop, speed setting, etc.
2: Output interface: Connect the motor output end, convert the AC output of the inverter into the three-phase AC required by the motor.
3: Communication interface: can be used to communicate with the host computer or other equipment to achieve remote control.
4: Other common interfaces: such as temperature sensor interface, access temperature sensor, used to monitor the temperature of the inverter, in order to achieve overheat protection; The encoder interface can be connected to the encoder for closed-loop control; Auxiliary power port used to provide auxiliary power for control and communication modules.
In short, the function of the frequency converter interface module is to connect the frequency converter with the outside world to achieve control, communication and other functions. For different types of frequency converters, the type and number of interfaces are also different, and users need to choose the appropriate frequency converters and corresponding interfaces according to actual needs in the process of use.
The inverter interface module can detect the speed and direction of the motor and pass this information to the inverter so that the inverter can adjust the speed and direction of the motor accordingly. In addition, the frequency converter interface module can also convert the control signal of the frequency converter into the control signal of the motor, so as to control the start, stop, speed and direction of the motor. The frequency converter interface module is usually composed of a circuit board, connecting wires, terminal blocks, etc., and can be customized according to different motor and control needs
