AB Rockwell 1756-L81E control processor and operator interface meet the requirements of space, flexibility and reliability, and provide rich functions, so that users can easily configure most applications of frequency converter. It is flexible, space saving and easy to use. In the application of mechanical tools, fans, pumps, conveyor belts and logistics processing systems, speed control is an economical and effective choice.

AB Rockwell 1756-L81E control processor AB Rockwell inverter principle - integrated PID controller can automatically adjust the output frequency and process variables.

Three programmable frequency hopping bands prevent the inverter from continuous operation at resonance frequency to avoid mechanical damage to the optional fan/pump curve, and provide voltage reduction mode for centrifugal fan and pump loads AB Rockwell 1756-EN2TR, a new original_ When the system demand decreases to the preset standard, the machine will be automatically shut down; When the system demand increases, the machine starts automatically.

In some unmanned environments, when the system is shut down and then restored, the inverter will restart automatically.

◆ Special inputs such as Freeze/Fire and Purge can be directly connected to emergency safety systems such as fire protection.

1756-IB16 principle RS485 communication is integrated into inverter

The built-in modbus rtu and Johnson sys n2 protocol are optional parameters, which do not require additional software and hardware support to drive the price of the serial interface (dsi) communication module and accessory AB Rockwell 1756-EN2TRXT *.

◆ Use DriveExplorer and DriveTools to easily program, monitor and control the drive - the whole set of frequency converter complies with UL standards, which improves the flexibility of installation and allows the frequency converter to be directly installed in the switch cabinet.

The circuit breaker and contactor bypass equipment of the inverter can be started by combining the operation panel, controller, communication and pre installed power supply through simple assembly.

AB Rockwell 1756-EN2TR brand new and original ◆ Three pairs of contactor contacts are provided for the full set of inverter bypass contactor. When the frequency converter is in bypass mode, the function of the frequency converter can be tested and the frequency converter can be isolated.
