1756-DHRIO AB罗克韦尔变频器原理

1756-DHRIO Specification AB Rockwell inverter principle
_ Integrated PID controller can automatically adjust the output frequency and process variables.
Three programmable band hops prevent the inverter from operating continuously at resonant frequencies to avoid mechanical damage
Optional fan/pump curve provides a voltage reduction mode AB Rockwell 1756-EN2TR new original _ sleep function for centrifugal fan and pump load, which automatically shuts down the machine when the system demand decreases to a preset standard; When the system demand increases, the machine starts automatically.
In some unmanned environments, when the system is shut down and then recovered, the inverter automatically restarts
◆ Special inputs such as Freeze/Fire and Purge can be directly connected to emergency safety systems such as fire
1756-IB16 Principle RS485 communication is integrated into the inverter
The built-in modbus rtu and Johnson sys n2 protocols are optional parameters and do not require additional software and hardware support to drive Serial Interface (dsi) communication modules and accessories AB Rockwell 1756-EN2TRXT* Price
◆ Easily program, monitor and control drives with DriveExplorer and DriveTools
_ The complete inverter complies with UL standards, increasing installation flexibility and allowing the inverter to be installed directly in the switch cabinet.
The inverter’s circuit breaker and contactor bypass devices can be activated selectively through a combination of operating panels, controllers, communications and pre-installed power supplies with a simple assembly.

AB Rockwell 1756-EN2TR New original ◆ Complete inverter bypass contactor provides three pairs of contactor contacts. When the inverter is in bypass mode, the function of the inverter can be tested and the inverter can be isolated.
