Mechanical specifications setting
Set the following parameters according to the specifications of the machine used. Refer to 10.4 (Application
examples) on
∗1
Set the parameter according to the specification of the machine used.

The increment applies when
Pr.21
= "0 (initial value)".
∗3
The increment applies when
Pr.358
= "0 (initial value)".

Set "114" for the X114 signal.
109
—
Set "109" for using the Stored
winding diameter clear (X109) signal.
117
—
Set "117" for using the Winding length
clear (X117) signal.

Winding/unwinding selection
—
0: Winding shaft
1: Unwinding shaft

Winding diameter storage
selection
—
0: Not stored.
1: The present roll diameter is stored.
1247
Winding diameter change
increment amount limit
Set the maximum change in 0.001
mm increments per roll diameter
calculation.
1243
Gear ratio numerator (follower
side)
Set a gear ratio when the motor shaft
has a reduction gear. (The increment
is 1 for each parameter.)
1244
Gear ratio denominator (driver
side)

First acceleration time for line
speed command
Setting is required in 0.1 second
increments when the cushion time is
not considered for the line speed
command
395
First deceleration time for line
speed command
101
Second deceleration time for
line speed command
Set the time in 0.1 second increments
as required (for example, for rapid
deceleration)
. Turn ON the X105
signal to enable the setting.
393
Line speed command
acceleration/deceleration
reference
Set the reference line speed (travel
amount per minute) in 0.1 m
increments for the acceleration/
deceleration time for the line speed
command
1231
Material thickness d1
—
Setting is required in 0.001 mm
increments when thickness is used
for winding diameter calculation.
1252
Dancer lower limit position
—
Setting is required when the initial roll
diameter calculation is necessary for
dancer feedback speed control
(0.01% increments for
Pr.1252
, 1 mm
increments for
Pr.1255
).
