How AC Drives Reduce Energy Costs in Industrial Systems
The invention of the variable frequency drive has forever shifted the tide of industrial automation for the better. It introduced a new way to control a motor by varying the AC power frequency fed into it; the higher the supplied frequency, the faster the motor spins. This same concept has been refined over years of real-world data to produce today’s modern AC drives. While AC drives are chosen for superior motor control performance, they also offer a faster ROI through energy savings, giving users a win-win scenario. While we would like to tell you that plugging an AC drive into your system will cut electricity costs by half, the truth is more nuanced. Electric motors are everywhere you look. Check outside your window, and your AC unit has an electric motor. The product conveyors at your local market’s checkout line run on electric motors. Step into an industrial setting and you may spot a centrifuge, large cooling fans, pumps transferring beverages, a conveyor moving product, or...

The Most Common SLC 500 Failures and Why They Occur
For years, the Allen-Bradley SLC 500 controller family, known for its modular design and dependable discrete control logic execution, has been a core platform in industrial automation. However, maintenance professionals are more often faced with predictable hardware deterioration patterns as these older controllers age inside operational production facilities. To reduce unscheduled downtime and extend the operational life of installed systems, it is essential to understand the underlying causes of these vulnerabilities. Common failure types include electrical breakdown at the component level, lithium battery depletion, communication interface burnout, and environmental vulnerability. Rather than relying on reactive troubleshooting, automation specialists can implement proactive replacement plans by evaluating these failure sources. By methodically breaking down the key failure vectors in the SLC 500 hardware ecosystem, industrial facilities can reduce obsolescence risks, avoid...

Understanding Torque Control vs. Speed Control in Industrial Applications
Speed control and torque control are the two main operating modes used by servo drives and variable frequency drives (VFDs) to run primary AC and DC electric motors. The drive’s internal control loops govern output voltage, current, and frequency based on the approach chosen under Torque Control vs. Speed Control system topologies. Torque control modulates active stator current to provide precise rotational force independent of speed variations, while speed control prioritizes maintaining the target shaft velocity regardless of load fluctuations. To implement the best control mode, we will analyze this article as Torque Control vs Speed Control, process stability, safety, and energy efficiency; system engineers must examine load characteristics, feedback devices, and mechanical dynamics. Order Allen-Bradley Servo Drive 1398s Here The motor drive operates as a closed-loop velocity regulator in speed control mode, with the inner torque reference being adjusted by the outer control loop...
