Understanding the real factors limiting servo gains, and system performance, makes it easier to devise counteracting strategies. Curt Wilson • Vice President of Engineering • Omron Delta Tau Here’s a piece of conventional controls wisdom – if you want to increase system performance, raise the gains. For non-specialists in industry who are trying to optimize […]

New standalone accessory cards from American Control Electronics prevent false alarms
The new CMC Series standalone accessory cards from American Control Electronics provide an adjustable current limit alarm for any dc motor controller, preventing false alarms due to predictable increases in current draw. This feature-rich current sensing module is a valuable tool for new and existing systems where an added level of monitoring and protection is […]
What is a motion profile?
Servo applications require defined, controlled movements, often to move a part to a specified position at a precise velocity or along a predetermined path. A motion profile provides the physical motion information and graphically depicts how the motor should behave during the movement (often in terms of position, velocity, and acceleration) and is used by […]
Motion technologies and software for next-generation eBikes
Since their emergence in the early 1990s, eBikes have undergone a steady series of improvements in range, reliability, and performance that have won them a growing number of loyal users worldwide. Equipped with specially engineered frames, high-capacity Li-Ion batteries, and highly efficient drive control electronics, today’s eBikes have become a low-carbon option to cars for […]
Programmable logic controller features built-in IIoT capability
Weintek has integrated CODESYS and IIoT Gateway into the cMT-CTRL01 – IIoT Programmable Logic Controller. The new model with built-in CODESYS, in addition to working with all iR modules, features IIoT Gateway protocol translation and EasyAccess remote access service, all of which justify its prime role in a smart automation system. With built-in Gateway, cMT-CTRL01 […]
What is hunting in the context of motion control and how is it addressed?
When a linear or rotary axis must follow a predefined move profile to reach or maintain a precise position, speed, or torque, a closed-loop servo system is often the best choice. Feedback from an encoder — mounted on the motor or directly on the axis — provides information regarding the system’s actual state (position, speed, […]
Video: Yaskawa GA800 ac drive for industrial applications
In a recent Design World video with my super-smooth colleague Mike Santora, I got the chance to play with a GA800 ac drive demo from Yaskawa America Inc. This VFD includes network communications, embedded functional safety, and easy-to-use tools (including a smartphone app) for configuration and remote access. Yaskawa sent us a sample of the […]
