Appendix C Application Notes
• Par 763 [PID Feedback] contains the raw feedback counts from the analog
input signal received from the transducer position (dancer) or tension
(load cell)
• Monitor the tension set point for a torque winder application in Par 1194
[Act Ten Ref Pct]
• Configure the PID feedback gain in Par 1254 [PID Error Gain]
• Limit the PID correction error using Par 757 [PID Clamp]
