With the latest upgrade to its ACOPOSmulti multi-axis servo drive, B&R now enables even shorter cycle times down to 50 μsec. Highly dynamic processes can now be controlled more precisely than ever. For demanding motion control applications, such as those found in the printing and packaging industries, movements must be controlled quickly and precisely. The […]
Servo Drives
Don’t forget these two things when selecting an amplifier for a servo-motion application
Using software to size motion designs is rewarding because engineers can efficiently predict which products are suitable for the application at hand. But key considerations (sometimes missed) when selecting a servo amplifier are those of dynamic braking and regenerative resistor braking.

New panel-mount servo drives from AMC for brushed, brushless dc motors
The AB25A100 PWM servo drive from Advanced Motion Controls is designed to drive brushless and brushed dc motors at a high switching frequency. The drive is fully protected against over-voltage, under-voltage, over-current, over-heating and short-circuits across motor, ground and power leads. Furthermore, the drive can interface with digital controllers or be used stand-alone, and requires […]
New dual-axis AKD2G servo drive from Kollmorgen
Kollmorgen’s new dual-axis AKD2G Servo Drive is one of the most power-dense industrial servo drives on the market. It substantially reduces mains wiring, fuses, and filtering to save significant panel space and cost. The AKD2G features expandable I/O (without increasing the size), removable memory, dual-channel STO, and the first drive-resident graphic display in the industry. […]
When do you need a linear amplifier versus a PWM drive?
Servo drives — also referred to as servo amplifiers — can be classified by the type of output stage they use: • Pulse-width-modulated (PWM) amplifier output stage or • Linear amplifier output stage. Of the two types, PWM drives are more common in general motion control applications because they provide more power to the motor, […]
Application example: Motion components on a typical form-fill-seal machine
Form-fill-seal machines are used to package edible powders, dry food, and liquids into bags and pouches. It’s a common machine design that comes in versions for both continuous and intermittent operation. No matter the design, top design objectives for form-fill-seal machines are high throughput with minimal downtime and the ability to reconfigure the machine to […]
Digital printing pairs with a machine capable of handling its varied output
VITS International makes sheeting and finishing machines for packaging, printing, and converting. The OEM saw the digital-printing market needed finishing capable of commercial production speeds. So VITS designed and built the SPRINT Variable Data Finisher with a Bosch Rexroth drive and control platform to meet the demand. Digital inkjet printers can execute output comparable to […]
Difference between continuous ratings and holding continuous loads (an ac servo-motor terminology primer)
For applications primarily needing the holding of a load with little movement, there are special servo-motor sizing considerations. But confusion often arises from the terminology used to describe such designs — especially from the common use of the term stall in the servo-motor industry. Here we clarify the definition in context and then relate it […]
Control Techniques announces new servo drive
Control Techniques, part of the Nidec group of companies, has revealed its new generation of advanced servo drive technologies. The new Digitax HD servo series delivers ultimate motor control performance and flexibility from a uniquely compact package. Targeting high axis count automation systems, Digitax HD provides all of the benefits of a modular system with […]
