Initial Setting
value value
0 1 1: Tension PI gain tuning starts.
Set the target amplitude for the limit cycle. Start tuning with a
9999 1% small value and gradually increase the value while making
sure that tuning causes no problem.
0 0 0:Winding, 1: Unwinding
Set the initial roll diameter (the maximum diameter of an
2 mm 400 mm
unwinding roll or the minimum diameter of a winding roll) with
1 mm 280 mm
high accuracy.
1 10
Set the gear ratio of the unwinding roller (shaft) with high
accuracy.
1 12
Setting is recommended when the results of the roll diameter
9999 0.1 s
calculation change significantly.
Setting Pr.1247 = "9999 (initial value)" disables the roll
diameter calculation.
9999 0.1 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
4 4
to the result of the roll diameter calculation.
