Hi guys, I have a retrofit project for a small packaging machine using a M90-TA2-CAN. Among others, i want to control the speed of a 3-phase motor using a 0-10VDC analog output. The machine is already equipped with a Frequency inverter drive and the speed is adjusted by a 1K potentiometer. Now the customer prefers to adjust the speed via HMI... The drive has a +10V and ground source which passes though the pot and the wiper result is connected to speed reference terminal. There is no terminal for my 0V PLC analog output and therefore i can't use the analog output of my M90. Any ideas how to solve this problem? Thanks in advance, Kikis
hi, I have a project and require communication between a ABB drive and V280 unitronics, where v280 is the master, anyone can help me or suggest how I start? thanks, pd. I have done this type of communication but with other brands, this brand only cut I made the flight program without communication inputs and outputs only analog and digital.
