Description
Defines the multiplier to boost the diameter estimation
responsiveness to a change. Normally the estimated
diameter change step depends on actual motor speed. If it
does not give enough agility for necessary corrections, set
the value of this parameter greater than 1.0. If estimated
diameter is changing too rapidly, set the value of this
parameter less than 1.0 (in this case check the settings of

74 Application
Multiplier.
Defines the delay after which the multiplication defined by

effective. The delay counter is started by the rising edge of
the diameter change.
Time delay.
Defines the multiplier for widening the range of the allowed
change rate of the actual diameter at start. Setting this
parameter to 2 doubles the allowed rate of the actual
diameter change. Widening can be used at start with partial
rolls to correct the possible error between the actual and
estimated diameter of the roll.
Multiplier.
Defines filter time for the motor speed component in the
estimation routine.
Filter time.
Displays diameter estimation based solely on the load/line
speed ratio without any ramping or filtering.
This parameter is read-only.
Raw diameter estimation
Displays the actual diameter calculated based on line-to-
motor speed ratio.
This parameter is read-only.
Calculated diameter.
Displays the scaled actual diameter value coming from
diameter feedback source (parameter

Src).
This parameter is read-only.
