Sizing a motor for a servo application requires evaluating the move profile and torque requirements to determine the mechanical demands of the system, such as maximum velocity and acceleration, RMS and peak torque values, and load-to-motor inertia match. Once the motor is chosen, the next step is to select a drive. On the surface, selecting […]

400-Volt servo motors — now with Yaskawa Sigma-7 performance
The Drives & Motion Division of Yaskawa America, Inc. announces the addition of a complete line of 400 Volt servo motors and amplifiers to its flagship series of Sigma-7 servo systems, extending the performance advantages of Sigma-7 products to all types of industrial users. The new 400 Volt offering includes a completely new amplifier design […]
What are servo drive loops?
Servo drives, also called amplifiers in the motion-control industry, take a command signal for position, velocity, or current and adjust the voltage and current applied to the servomotor based on closed-loop feedback. In fact, a servo drive is just one element of a motion control system, which includes a servo motor, the drive, controller, and […]
Siemens introduces new servo drive system
With its Sinamics S210 converter designed specifically for use with the newly developed Simotics S-1FK2 motors, Siemens is offering a new and innovative servo drive system in an initial offering from 50 to 750 W. The converters come with integrated safety functions and enable rapid engineering via motion technology objects in Simatic S7-1500 controllers. They […]

Available now, these new models offer high efficiency in a compact design and are targeted towards AGVs and mobile applications. 100 A Peak Current Output 60 […]
What is modulo positioning?
In motion control, there are typically two types of positioning that can be used for a linear or rotary axis: relative, in which each position is based on a previous position, regardless of the actual position of the axis; or absolute, in which each position is referenced to a home, or zero, point. Axes that […]
New space-saving AMP8000 distributed servo drive system from Beckhoff
Beckhoff Automation’s new AMP8000 distributed servo drive system breaks new ground for modular machine concepts. The space-saving AMP8000 integrates a servo drive directly into a servomotor and features an ultra-compact design. By relocating the power electronics directly into the machine, a control cabinet only needs to house a single coupling module in order to supply […]
How to address overshoot in servo control
Updated August 2018 || There are three characteristics that indicate when a servo system is properly tuned: response time, settling time, and overshoot. Response time is the time it takes the system to reach a specified percentage of the target value, while settling time is the time it takes for the target value to be […]
Why are servo drives also called servo inverters, amplifiers, and controllers?
Let’s start with the term servo drive. Here’s what a drive does in a servo system: It basically takes an input signal from a controller and amplifies that signal which is then sent to the motor. And in that description is the key. A drive serves to amplify a signal. Amplification is needed because control […]
