Communication protocol: Modbus for VFDs


KEB offers a full line of VFDs with Modbus RTU and Modbus TCP communication options.


KEB’s F5 and F6 VFD products are scalable from 1Hp to 1000Hp. Units are offered in both 230V and 480V power classes. The drives support both open and closed-loop motor control. They can be used to drive servo motors and have an internal 32-bit positioning function for motion control applications.


KEB’s F5 VFD platform offers solutions for both Modbus RTU and Modbus TCP/IP applications.


The Modbus communication is handled through a flexible operator which is available for all control card types.


The F5 is offered in different power gradients up to 1000 Horsepower. Units are offered in dedicated 230V and 480VAC power classes.


The F5 is capable of running both induction motors and AC servo motors. It supports a variety of different control platforms for open loop and closed loop applications. The F5 and F6 drives even supports an internal 32-bit positioning module for motion control applications.


The F5 has a compact form factor and is available with an integrated braking transistor for regenerative applications.
