Top 7 KEB blog posts 2017

KEB’s top 7 of 2017

In 2017 KEB America was able to share more information than ever before with our fans and followers. We’ve been working hard to research new trends, create informative and fun videos, and put together interesting graphics and images to illustrate the control and automation world of today.

 

We wrote about new technologies and the old, tried-and-true tech we love. We made videos with some KEB customers to highlight our products in the field, and animations to show how it all works. We wrote about application-specific scenarios to give specific use-cases for KEB products. We’re so pleased to see the interaction on our blog, Facebook, Twitter, and even in person at trade shows like Pack Expo. There’s a lot more to come in 2018, so please stay tuned!

 

In case you missed it, here’s a list of the top 7 posts of 2017.

 

7. PLC based elevator and escalator controls with KEB Automation (video)

 

 

KEB has many years of experience in PLC-based Elevator, Escalator, and Lift controllers. PLC control is often preferred for transit and public installations because components can be sourced on the open market. KEB PLCs are designed with serviceability in mind – components and chipsets are available for many years.

 

 

6. Robotic brakes for precise control

 

The robotics industry is diverse and becoming more prevalent every day from the manufacturing floor to the operating room. With it comes unique and challenging engineering problems pertaining to holding the arms and joints accurately in place. Robotic brakes for precise control is one way KEB can step in and lend a helping hand.

 

5. What is Functional Safety over EtherCAT, FSoE?

 

Failsafe over EtherCAT PLC

 

With a number of new KEB Functional Safety over EtherCAT (FSoE) products on the horizon, this post is a primer on FSoE and why it is important to machine builders.

 

 

4. VFDs for Single phase applications

 

This post outlines the use of VFDs in single phase applications  – why a person would want to add a VFD, sizing considerations, a rough cost comparison, and the advantages a VFD offers.

3. Short Circuit Current Rating (SCCR) and Fuse Selection

 

Protecting electrical components from short circuit current is essential when designing an electrical panel. But what exactly is the short circuit current rating (SCCR) of electrical components? More specifically, how is the SCCR calculated? This post will go through a detailed procedure for determining the SCCR of a system, focusing on the differences between direct and isolation transformer fed systems.

2. Uninterruptible power supply and regenerative energy in elevator applications

 

This post describes how to implement uninterruptible power supply and regenerative energy in elevator applications using KEB’s R6 line regen drive.

 

 

 

1. How Pulse Width Modulation in a VFD works

 

What is PWM? The process involved in inverting the DC voltage to the variable voltage variable frequency (VVVF) AC voltage in the inverter section of the VFD is called pulse width modulation or PWM.
