Value Range Description
B0‑25
Pre‑drive roll diameter
calculation function
0
0: Disabled
1: Enabled
This parameter is valid only when B0‑07 is set to 1.
When the roll diameter is calculated based on
accumulative thickness, the roll diameter
increases/decreases with the number of
revolutions. Set B0‑25 to 1 to avoid accumulative
error caused by invalid roll diameter calculation in
the pre‑drive mode.
You can set this parameter according to the actual
operations.
3.6.16Constant Linear Speed Mode
In this mode, the running frequency for winding and unwinding is automatically
calculated based on the set target linear speed.

0.0% –100.0% to
+100.0%
For pre‑drive, the running
frequency is automatically
calculated based on the linear
speed and roll diameter to ensure
matching with the linear speed of
the material. For small deviation
of linear speed, set B0‑19 to
increase or decrease the running
frequency during pre‑drive,
ensuring accurate linear speed
matching.
