Can a variable frequency drive with the ability to control motor torque, be programmed to run at a certain speed and torque? Or can you only control one of these variables because a change in one will affect the change in another? I noticed that in certain drives, there is speed control and torque control. Are these isolated from one another? Is it possible that when torque is controlled, the speed of the drive is somehow proportional? I understand that torque multiplied by speed is power. Is it possible to set a motor to operate at a certain torque and speed as long as it is within the motor’s rated power and torque? The reason I ask these questions is because I’m trying to control tension and speed of a moving web. I believe that the torque produced by the motor will determine tension, however, I don’t understand how to change how fast the web will move. It seems like if the tension remains constant, than that would mean that the motor torque would remain constant and the torque would not effect the speed. Any help?
