Troubleshooting Tip: No Response from Amplifier on Your Controller
Always check to make sure the proper power is being supplied to the amplifier. For example our A4 Amplifier requires 24 VDC input whereas a M3200 utilizes 120/240 VAC. If the wrong voltage is supplied to the amplifier, the amplifier will not work and could potentially permanently damage the amplifier. Ensure the output signal wires […]

What is Progressive Gain?
Most people that are tasked with the tuning of controllers are familiar with three terms; Proportional Gain, Integral Gain, and Derivative Gain, better known as PID. These adjustments are often referred to as “Controller Gain” as they determine the controller’s responsiveness to disturbances. However, in many cases, the dynamic behavior of the actual process may require […]

Dancer or Load Cells – Which Should I Use?
I am frequently asked this question, and my standard answer is that: it depends. It depends upon the type of process (slitting, printing, coating, laminating, die cutting, etc.), the range of products being run (rigid, extensible, deformable, etc), whether flying splices and/or turrets are involved, and incoming roll condition. Dancers are very effective at minimizing […]
