Remarks
For the intermediate shaft, set the
roller (reel) diameter in millimeter in
both Pr.1235 and Pr.1236.
Set "114" for the X114 signal.
Set "109" to use the Stored winding
diameter clear (X109) signal.
Set "117" to use the Winding length
clear (X117) signal.
0: Winding shaft
1: Unwinding shaft
0: Not stored.
1: The present roll diameter is stored.
Set the maximum change in 0.001 mm
increments per roll diameter
calculation.
Set a gear ratio when the motor shaft
has a reduction gear. (The increment
is 1 for each parameter.)
The increment is 0.1 seconds.
Setting is required in 0.1 second
increments when the cushion time is
not considered for the line speed
command.
∗2
Set the time in 0.1 second increments
as required (for example, for rapid
deceleration). Turn ON the X105
∗2
signal to enable the setting.
Set the reference line speed (travel
amount per minute) in 0.1 m
increments for the acceleration/
deceleration time for the line speed
command.
∗3
Setting is required in 0.001 mm
increments when thickness is used for
winding diameter calculation.
