Marcelo Posted March 9, 2022 Report Share Posted March 9, 2022 Im working with servo UMD-0010E-B3 and motor UMM-0010EA-B3. PLC is USC-B5-TA30. Would like to know if there is a way that the servo make this. Have to make a complete spin within a given time. No care about the speed during most of the spin. At a given point of that spin, its speed has to be equal to a given one. Couldn´t find a solution . I would appreciate if you could help me. Thanks.

MVP 2021 kratmel Posted March 9, 2022 MVP 2021 Report Share Posted March 9, 2022 As far as I know - a rotary knife can not be implemented using the capabilities of the Unistream+Servo platform. This application requires high-speed positioning circuit processing with two encoders - material speed and knife motor speed. Such applications require specialized processing modules and appropriate technological software. I am familiar with solutions from Siemens, Nidec (Control Techniques) and Koolmorgen. The only case where this application could be built yourself with free software sample code - is a hardware kit from Control Techniques (Unidrive SP + SMEZmotion with Power tools Pro software) but Unidrive SP is out of production. All other solutions require additional costs for both hardware and software. You can contact support@unitronics.com for information. 1 Quote Link to comment Share on other sites More sharing options...
