Name Default
Value Range Description
B0‑15
Roll diameter filter
time
5.00s 0.00s to 10.00s
This parameter is enabled only when B0‑07 is
set to 0.
You can set B0‑15 to filter roll diameter
calculation results and suppress roll diameter
jitter.
A larger value of B0‑15 means smoother
calculated roll diameter and longer delay in
roll diameter changes.
Rule: When the roll diameter changes linearly,
the time that the calculated roll diameter lags
behind the actual roll diameter is basically
equal to this parameter value.
B0‑16
Roll diameter
change rate
0
0: Disabled
0.1 mm/s to 1000.0
mm/s
This parameter is enabled only when B0‑07 is
set to 0.
You can set B0‑16 to a non‑zero value to limit
the change of roll diameter per unit of time
and prevent abnormally fast change. An
excessively low roll diameter change rate may
result in large delay in roll diameter
calculation. Set the change rate properly
based on the actual conditions, for example,
based on the maximum change rate
corresponding to the linear speed of 100.0 m/
min.
B0‑17
Roll diameter
change direction
limit
0
0: Disabled
1: Decrease inhibited
during winding, and
increase inhibited
during unwinding
This parameter is enabled only when B0‑07 is
set to 0.
You can set B0‑17 to limit the roll diameter
change direction. Use this function only when
B0‑16 is set properly; otherwise, abnormal roll
diameter fluctuation may occur and result in a
large deviation of the roll diameter calculation
result.

roll diameter calculation only when B0‑07 is set to 1)
Para. Name Default
Value Range Description
B0‑29
Number of pulses per
revolution
1 1 to 60000
This parameter specifies the number of
pulses per revolution of the reel.
B0‑30
Revolutions per layer
1 1 to 10000
This parameter specifies the number of
revolutions for each layer of winded
materials, generally used for wire rods. For
wire rods, set B0‑30 to 1.
