Description
Selects the gear coefficient 1 or 2 used by the control
program.
Uses value set in parameter
Uses value set in parameter
Source selection (see
152).
Defines the material thickness in millimeters. For a wire-
winding application, enter a value equivalent to the wire
diameter divided by the number of turns needed to complete
one full width of the spool.
Material thickness.
Defines the roll lay-down width.
Roll lay-down width.
Defines the density of the web material. The table below
gives examples of densities for some materials. In a wire
winding application, density values smaller than the actual
density of the material can be used since the material is not
necessarily wound evenly to the spool and the inertia will
therefore be smaller.

Selects the source for material length.
Zero.
Material length is estimated from parameter
diameter. Estimated length can be checked from parameter
09.21 Estimated
Material length is measured from an encoder feedback
coming to the drive.
Note: When using this selection, set the virtual roll counter
settings in parameter group
