Fail‑Safe Motor Circuits: When Loss of Power Moves You Toward Safety

Part 1 of a 2-part series. A practical look at the failures that plague motor drive systems, even those that are rated to be fail-safe.


Tutorial: How to Set Up a Light Curtain

Tutorial: How to Set Up a Light Curtain

Learn how to align and configure the parameters of a light curtain using a send/receive pair of SICK deTec4 light beam curtains and the new DCM4 extension module for advanced operating modes.


Customizing Light Curtain Configuration: Muting and Blanking

Customizing Light Curtain Configuration: Muting and Blanking

Some safety applications aren’t a simple on/off at all times; they need objects to pass through a light curtain without stopping the machine. For these, we turn to muting and blanking features.


Installing and Configuring Light Curtains

Installing and Configuring Light Curtains

Learn about safety light curtains: which one will fit your application, how to choose the proper size, and how to properly process the output signals.


The Spectrum Between Human and Machine: The Industrial HMI

The Spectrum Between Human and Machine: The Industrial HMI

Although ‘HMI’ has become synonymous with a durable, rugged touchscreen measuring 7 to 21 inches and mounted in a control cabinet door, the reality of the interface extends far beyond this device.


Mitsubishi PLC to VFD Control: RS-485 Communication

Mitsubishi PLC to VFD Control: RS-485 Communication

This guide shows you how to set up RS-485 communication between the FX3U PLC and the FR-D700 inverter with the FX3U-485-BD. You can control speed and monitor the system using ladder logic.


Methods of Controlling Motor Speed With a VFD

Methods of Controlling Motor Speed With a VFD

Motor speed control can be a tricky process, due to the variety of options. In a VFD, speed can be controlled using fixed values, digital or analog signals, or communication networks.
