Using the CiA 402 Drive Profile for Motion Control Applications

The CAN in Automation (CiA) group has created unique device specifications for certain applications.  One example we’ve highlighted before is CiA 417 which defines the CANopen Lift Application.  Another is CiA 402 which defines the specification for devices that operate motors.  This can include VFDs, Servo Drives, stepper drives, etc.   This post gives an overview of some of the main features of CiA 402, why a person would want to use it, and some considerations.     CiA402 – A Profile for Drives and Motion Control The CAN bus protocol has had a lot of success since its initial...

Modbus TCP communication protocol for drives

As a system integrator, you may work with many brands of PLCs, depending on what your client prefers or already has installed. When it comes time to choose a VFD for their installation, it’s handy to have a versatile drive with communication options at the top of your list.   The F5 VFD from KEB America is popular with integrators and end users for this reason. Rather than having to accommodate limited options, the F5 is available with communication ports that connect it to a range of 3rd party PLCs. Modbus® TCP is just one of the many communication protocols available...

Modbus VFDs

  Communication protocol: Modbus for VFDs   KEB offers a full line of VFDs with Modbus RTU and Modbus TCP communication options.   KEB’s F5 product is 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.       Related Posts              

Using the HMI LC as an Intelligent Network Gateway

Historically, connecting two different communication networks was handled by a dedicated network gateway.  We worked on an application a couple months ago where we were able to implement this gateway functionality in an HMI LC.  This is what it looked like.   The customer’s main PLC was an Allen-Bradley communicating with EtherNet/IP (protocol 1).  The AB PLC connected to a machine panel that used a KEB HMI LC.     The HMI LC used EtherCAT (protocol 2) to control a 200Hp F6-K EtherCAT VFD.       EtherCAT for the VFD EtherCAT was chosen because it provides a high-speed CAT5...

DC to AC Elevator Modernization

  The benefits of elevator modernization – updating a system to AC gearless using KEB drives and regen units – include power savings, lower noise levels, faster floor-to-floor times and less carbon dust floating around the motor room.   DC motors were great in their day, but newer AC gearless motors offer increased performance, better power savings and the ability to regenerate excess power to put back on the building’s power grid.   For more info on TEI Group, visit their web site teigroup.com   Learn about KEB Elevator products   For more great videos, subscribe to our YouTube channel...

Modbus RTU communication protocol for VFDs

The F5 inverter from KEB America has been a popular drive for many years due to its flexible design, range of available sizes, and lengthy list of options, including communication protocols.   One of these protocols is Modbus®, and the most commonly used version is Modbus RTU. This type of protocol is often seen in industrial automation settings because it’s easy to integrate and use, which is why KEB has made it part of the modular communication feature of the F5 VFD.   Modbus Overview Modbus RTU uses the RS-485 serial port to transmit communication between machines. Information is sent between...
