7.22.6.2 Min. reel diameter (rewinder)
Dimensioning diameter
The dimensioning diameter is the diameter which results at the end of the acceleration phase. DSD
calculates this value automatically and considers it in the drive dimensioning.
[7-235] Increase in the reel diameter during the acceleration phase without reduction of the winding speed
