PID set point
• Use a commanded tension value after taper compensation to set the set point for tension feedback. Select the tension
command input method in Pr.804 Tension / Torque command source selection.
NOTE
• Refer to page 118
Tension feedback input selection (Pr.363)
• Use Pr.363 Dancer / tension sensor feedback input selection to select the input terminal for tension feedback.
