Hi steffo Have youincluded Accleration Compensation and Friction Compensation in your Torque limit. You need Accleration compensation to maintain constant torque during accleration / deceleration, and Friction compensation for compensating for different losses with change of speed. These are important especially if Torque limits are low !! Hope this helps Cheers Navnag |

Hi steffo The Default Torque Limit ( P1520 , P1521 ) is 400% of Rated Motor Torque. Please Check the Motor Data and Torque Limit Parameter Settings in your configuration. How are you setting the torque limit? If you are setting the Torque limit through Profibus / Profinet then Pl check Reference Torque Setting : P2003 ( Default = Motor Torque ) 100% Setpoint from Profibus / Profinet = Reference Torque Hope this helps Cheers Navnag |

Hello steffo You need to do the following : a) Provide a small reverse speed setpoint to the unwinder c) Limit Torque in both directions ( Motoring / regeneration ) for Unwinder The Unwider tries to run reverse, however the Winder / other equipment will force it to run in forward direction at the Set Torque limit. This will establish Tension in the Line. Tip : You may need to De-activate Speed Setpoint / Actual value difference monitoring in Unwinder. Hope this helps Cheers Navnag |
