I'm working on an existing payoff of a wire machine. It has a motorized payoff controlled by a Control Techniques Commander SE AC Drive using a dancer arm mounted potentiometer connected to the drives speed control. Very basic control, when the dancer arm is down the speed is 0%, midway is 50%, and all the way up is 100%. The dancer arm also has a pneumatic tensioner
It works OK but as spool gets lighter or the tension is minimal, it struggles to keep a consistent tension.
I've worked on machines that have servos for dancer controls, but I don't have a lot of experience with using AC drives to do this. My initial reaction was to change it out to servo control but this setup almost works. Does anyone have any experience with AC drive dancer applications? This is a very no frills drive so I'm wondering if I couldn't upgrade the drive to make it do what they want.
