200
DIGITAL INPUT 3
Winder side
Selection of the winding/unwinding side: in case the selection is carried out via a digital
input: 0 =UP, 1 = Down
DIGITAL INPUT 4
Diam reset
Diameter reset. When this parameter is enabled, the diameter gets the starting value
selected with Diam preset sel.
If 2-4 different values of the starting diameter have been set, the selection has to be carried
out via some programmed digital inputs such as: Diam preset sel 0- Diam preset sel 0
If the value of the starting diameter is set via an analog input, set Diam preset sel = 3.
In case of a winder control, it is necessary to give a reset command every time a coil
change is performed by setting the minimum diameter value (winder empty diam.)
In case of an unwinder control, it is necessary to give a reset command every time a
coil change is performed by setting the maximum diameter value(winder maximum
diam.).
Enable the parameter Diam reset for a time longer than 20ms.
Reset the digital input status before the start
DIGITAL INPUT 5
Diam preset sel 0
DIGITAL INPUT 6
Diam preset sel 1
In case of a system with a winder or unwinder control, it is possible to set in Diam preset
0 the value of the starting diameter; for the winder control a minimum diameter, for the
unwinder control a maximum diameter. Set Diam preset sel =0 (do not set any digital
input as diam preset sel 0-diam preset 1). By starting the command of Diam reset the
value of diam preset 0 is entered in Roll diameter.
OPTION Menu
————> Torque winder
Torque winder En ; set Enable to enable the center wind function.
If the system requires it, it is possible to set this function (enable/disable)also via a
digital input.

PARAMETERS
OPTION Menu
————> Torque winder
————> Diam calculation
Wind/unwind
Winder/unwinder selection. Selection to be carried out only if the digital inputs are not set.
Minimum diameter Minimum diameter value in [mm]. Set 100mm
Maximum diameter Maximum diameter value in [m]. Set 0.7m
Line spd source
Number of the sampling parameter of the line speed. In order to get the real number to
be set it is necessary to add +2000H (8192 decimal) to the parameter number.
