Remarks
Winding
roller
Use Pr.358 to set the increment. Maximum
line speed (300 m/min) is set.
0: m/min (increment of the maximum line
speed)
If setting Pr.361 to "8", set a line speed
command value in this parameter.
5: Input via terminal 1
0: Signals for the actual line speed are not
input (the actual line speed is determined by
calculating from the line speed setting).
Acceleration/deceleration speed and time:
300 m/min for 30 seconds (same as the
10 s
setting of the intermediate shaft)
10 s
When "1" (storing roll diameters enabled) is
1 set, the input of the Stored winding diameter
clear (X109) signal is required.
1 0: Speed control, 1: Torque control
1: Servo lock
To limit output torque in the constant power
1
range, set "1" (constant torque).
0: Tension command given by analog input
0
via terminal 6 on the FR-A8AZ
1: Speed limit by the setting of Pr.808 or
Pr.809
Set the forward rotation speed limit.
The setting of 0.01 seconds for the
0.001 s
intermediate shaft is for noise precautions.
Set "1" (tension direction reversed) for the
unwinding roll because the direction of
0
tension in unwinding rolls is opposite to the
feeding direction.
0.0% (0 V) corresponds to 0 N and 100.0%
(10 V) corresponds to 300.0 N when
Pr.1401 is set to "1" (0.1 N).
100%
300 N
0 0: Winding, 1: Unwinding
Set this parameter for the roll diameter
calculation from the material thickness.
800 mm Set the initial roll diameter (the maximum
diameter of an unwinding roll or the
minimum diameter of a winding roll) with
100 mm
high accuracy.
Set the gear ratio of the unwinding/winding
roller (shaft) with high accuracy.
Setting is recommended when the results of
0.1 s the roll diameter calculation change
significantly.
Set the line speed command value to start
the roll diameter calculation.
