This video briefly shows the application of the ATO servo system in a linear slide.

ATO servo motor has 40mm to 180mm different square flange size, power rating from 50W to 7.5kW and speed range from 1000 rpm to 3000 rpm. so you can select the best one for your applications. In this video, ATO will show you servo motor linear actuator system for robotics.

In this video we've guided you through how to do VFD control wiring with a self-lock push button switch to run the motor in forward direction. We've covered everything from wiring to programming and even a test run. So just watch it through and hope you'll find it informative and helpful.

A question for your 4.5kW servo motor/controller

For your 4.5kW servo motor/controller, our performance requirements of the Idle Speed Test require very fast input changes and, likewise, very fast output speed changes. The rotational inertia and the available torque of the motor indicate that these speed changes are within the capabilities of the motor. However, I need to make sure that the motor controller is capable of responding to these fast input changes and also capable of controlling the motor to achieve these commanded output speed changes. What is the response time of the motor controller?

ATO Responded

The response time of the motor controller is 500Hz, and it is able to meet the performance requirements of idle Speed Test you inquire about.
