Lenze Americas has launched a series of MCM synchronous servomotors that delivers intermediate-level dynamic performance. Scalable, modular Lenze MCM motors are easy to control and optimized for a range of positioning tasks, including robotics, packaging equipment and handling systems. “Designed with an optimal torque and inertial mass ratio, our MCM servomotors give customers the precision […]
Motor thermistor relays monitor up to six motors
The new DTA7 Series of Motor Thermistor Relays from Carlo Gavazzi are capable of monitoring the temperature of up to six motors (via thermistors on the internal windings). This type of monitoring and control prevents false alarms, which may cause interruptions in production and expensive machine downtime. Features include universal power supply (which reduces the […]
New VFDs offer quick, easy setup
The new ACF Series from American Control Electronics is an open chassis microprocessor-based variable frequency drive (VFD) that offers the simplicity of a DC drive. ACF700 drives are designed for quick and easy setup without any programming, in contrast to the complex programming associated with standard VFDs. The drives are equipped with user-adjustable trim pots […]
FAQ: What are some PLC I/O, visual display, and networking options?
A PLC can be a highly customizable controller, depending on application needs. And with advances in technology, the options designers have continue to expand. Specifically, we focus here on three types of options; I/O (input/output), visual displays, and networking. I/O I/O options can be classified in several ways, including some basic groupings such as analog […]
BISSC-approved flange-mounted clutch-brake from Nexen
The Nexen Group’s new Flange Mounted Clutch-Brake Enclosed (FMCBE), offers food-production machine builders a clutch-brake with built-in hygiene features to prevent contamination. The FMCBE is BISSC-approved (Baking Industry Sanitation Standards Committee), and ideal for any environment where cleanliness is a primary concern. The FMCBE offers other significant advantages as well. Compared to electrically actuated clutch-brakes, […]
Leine & Linde adds speed monitoring to encoder
The Leine & Linde 1000 series rotary encoder with speed monitoring capabilities is used in applications where secure speed feedback is critical in order to protect motors, machinery or operators from risk of failure. This is especially useful on heavy moving machinery such as hoists, lifts, cranes and mining equipment, to name a few. Leine […]
Low-profile motors for arc segment and large diameter motion from Applimotion
The Infinity Series of low-profile, direct drive motors from Applimotion lets OEMs move light payloads in smooth and accurate arc-shaped and full 360-degree rotary motion profiles. Ultra-thin arc-shaped motor segments can be used individually or interconnected to create exact partial arc segment motion or full 360-degree rotary motion. Modular construction allows for virtually unlimited diameter […]
Ladder logic and other PLC programming options
The most common way to program early PLCs was using so-called ladder logic programming. Basically, a ladder logic diagram was a graphical way of representing the functions in a typical PLC and the control actions it would have to take. For instance, lines on a ladder logic diagram could include opening or closing a switch, […]
POSITAL adds Profinet interface to explosion-proof encoder line
POSITAL has added an optional Profinet communications interface to its explosion-proof IXARC rotary encoder family. These devices have been designed to comply with ATEX/IECEx directives for Category 3 electrical products and are suitable for Zone 1 and Zone 21 conditions (potential exposure to hazardous levels of explosive gases and dust concentrations). Areas of application for […]
FAQ: Where do PLCs operate?
Perhaps a better question would be where don’t PLCs operate? (or where PLCs aren’t used?) That may turn out to be a much shorter list. Briefly, a PLC (or programmable logic controller) is a stand-alone controller that users program to perform a sequence of specific tasks. The structure of a basic PLC program involves a […]
