Tuning the Belt Drive

Both the puller and cutter drives have a set of presets with similar functions. A

description for any parameter in this section applies to all drives.

Please refer to

Control Techniques documentation for additional information and setting descrip-

tions.

Common Tuning Controls

There are four values and two check boxes that are used to tune each puller drive

(Upper and Lower). These values are Inertia Ratio, Friction, Response and Time

Constant. Check boxes to enable Feedforwards and Time Constant are provided.

Please refer to Control Techniques documentation for additional information and

setting descriptions for Inertia Ratio, Friction Response and Time Constant.

The four values in the top section are Torque, Follower Error, Shunt and

Foldback. These values are read-only and help to show the effects of tuning.

NOTE: If a drive is too tightly tuned it will be more accurate but may consume more power, an

under-tuned drive will use less power but it will not be as accurate.
