When the unwinding direcon is overcompensated for, the unwinder will be
un
winding faster than the downstream process can accept, as a result of which
slack will develop in the material.
How to congure the acceleraon compensaon:
1.Set the acceleraon torque in the unwinding direcon with a factor < 100 % in the parame-
ter Evaluaon acceleraon torque negave. 40x5051:123
2.Set the acceleraon torque in the rewinding direcon with a value > 100 % via the parame-
ter Evaluaon acceleraon torque posive. 40x5051:122
Dierent mass ineras which result e.g. from dierent material widths or material densies
are taken into account in the form of a percentage via the parameter Moment of inera
adapon. 40x5051:119
The acceleraon compensaon is enabled via the control bit 26 = TRUE. 40x5050:010 Bit 26
