Tension build up problem in paperwinder drive ACS800.
I have a paper winder motor of 37 kw,68 amp, base rpm=1414, max torq-238 nm. The tension is not properly maintained & the paper is becoming loose.Also when the linespeed is becoming zero, the paper winder motor speed is becoming zero after some seconds. ACS800 drive is used in speedcontrol mode. Checked the coupling of the motor, found ok.Checked the torq filter2 parameter at different speeds, found stable.I have compared the parameters with the previous backups.Emg stop ramp, kps, tis parameters were slightly different. Paper dia calculation is via V/N. Mtor encoder f/b is also smooth.
Shall I go for ID RUN,Motor loss calculation?What other parameters I need to check?
