B0‑10
Initial roll
diameter source
0
0: B0‑11 to B0‑13
Parameter B0‑10 is used to select an input channel of
the initial roll diameter. When B0‑10 is set to 0, the
source of initial roll diameter is dependent on functions
55 and 56 (initial roll diameter selection terminal) of the
DI terminal and related to the winding mode.
By default, the source of initial roll diameter is set to B0‑
08 or B0‑09, depending on the winding mode. For the
relationship between the initial winding sources and
settings, see "

initial winding sources and settings

The initial roll diameter can be obtained through
calculation methods 1 to 4. When the preceding
calculation methods are used, the maximum roll
diameter (B0‑08) must be set correctly based on the
per‑unit relationship.

Note
When the system is shut down due to reel replacement, running faults, or other reasons,
the roll diameter often changes. To ensure accurate roll diameter during startup of the sys‑
tem, roll diameter reset must be performed by enabling the function 54 of the DI terminal
(roll diameter reset).
