353 Line speed command gain 1000 m/min 300 m/min
Use Pr.358 to set the increment. Maximum
line speed (300 m/min) is set.
358 Line speed unit 0 0
0: m/min (increment of the maximum line
speed)
360 Line speed command value 0 0
If setting Pr.361 to "8", set a line speed
command value in this parameter.

To limit output torque in the constant power
range, set "1" (constant torque).

1072 Tension reverse selection 0 1 0 0
Set "1" (tension direction reversed) for the
unwinding roll because the direction of
tension in unwinding rolls is opposite to the
feeding direction.
