PID set point (Pr.133)
• Set the set point for tension feedback in Pr.133 PID action set point.

600% +100%
500% (initial setting) 0%
400% -100%
• Set a value according to the full scale value of the tension detector to be used and the corresponding output voltage. For
example, when tension feedback is input through terminal 1 and the tension sensor outputs 10 V for 100 N (full scale
value), set 530% in Pr.133 to set 30 N tension.

NOTE
• Set Pr.52 = "86" to monitor the tension feedback value on a percentage basis.
Tension feedback input selection (Pr.363)
• Use Pr.363 Dancer / tension sensor feedback input selection to select the input terminal for tension feedback.
