Setting Pr.1247 = "9999 (initial value)" disables the roll diameter
calculation.
9999 0.2 mm
Be sure to change the setting from the initial value for the roll
diameter calculation.
Use this parameter to enable the primary delay filter relative to

Use this parameter to prevent the dancer roll from moving too
9999 0% much when the normal operation starts after the initial roll
diameter calculation is completed.
The setting value can be calculated from the setting of Pr.1253
