Diameter Calc
1166 [Diam Preset 2]
Third preset starting diameter. The value of this parameter must be
set between the value of Pars 799 [Minimum Diameter] and 1153
[Max Diameter].
Default:

1167 [Diam Preset 3]
Fourth preset starting diameter. The value of this parameter must be
set between the value of Pars 799 [Minimum Diameter] and 1153
[Max Diameter]. This parameter can be assigned to an analog input. If
an analog input is used, +10V corresponds to the value of [Max
Diameter] and the voltage corresponding to the minimum diameter =
10 x ([Minimum Diameter] / [Max Diameter]).

1168 [Diam Preset Sel]
Selects the starting diameter for the Diameter Calculation function.
• 0 = Par 1164 [Diam Preset 0]
• 1 = Par 1165 [Diam Preset 1]
• 2 = Par 1166 [Diam Preset 2]
• 3 = Par 1167 [Diam Preset 3]
This parameter can also be set via two digital inputs programmed as
57 “Diam Preset0” and 58 “Diam Preset1”; the selection in this case is
carried out with binary logic.

1205 [Diam Inc Dec En]
This parameter It is used to improve system stability for winder/
unwinder applications. If this parameter is enabled and if applied to a
winder, the calculated diameter can never decrease; if applied to an
unwinder, the calculated diameter can never increase.
Default:
