Hi, I am having an application in which we are having a Roller rotating via Powerflex 527 drive. The operator can change the speed of this roller from the HMI. In the PLC program, I see the programmer has used MAJ instruction for reading this speed from the HMI.
The operator is not able to change the speed on the fly, the speed change only takes place when he stops and starts the roller again, I guess it is due to MAJ instruction. Because as per the definition of the instruction it maintains a const. speed.
Is there any way around this so that the value of new speed entered by the operator in the HMI is updated in drive speed on the fly.
I am thinking of using MCD instruction instead. Will, that work?
Thank you,
