Application examples
Remarks
Winding
roller
Set the line speed command value to start the roll
diameter calculation.
Setting Pr.1247 = "9999 (initial value)" disables
the roll diameter calculation.
Be sure to change the setting from the initial value
for the roll diameter calculation.
Use this parameter to enable the primary delay
filter relative to the result of the roll diameter
calculation.
9999: Initial roll diameter calculation disabled.
1 (for winding roller): Linear taper profile
Set the roll diameter to start taper control.
Set the taper ratio.
1: Setting increment: 0.1 N, setting range: 0 to
1000 N
Set the tension command in the range of 0 to 300
N.
Commanded tension during stall mode = Tension
command value × Pr.1406
Set the speed limit to be used during stall mode.
Set the motor inertia for the inertia compensation
function.
Set the empty reel inertia for the inertia
compensation function.
Set the roll width for the inertia compensation
function.
Set the specific gravity of the material for the
inertia compensation function.
Set the acceleration time for the inertia
compensation function.
Set the deceleration time for the inertia
compensation function.
Set the frequency and the compensation value for
each setting of mechanical loss.
For setting, start measuring mechanical loss with
an empty reel attached at low speeds, and
gradually increase the set speed to find the speed
requiring mechanical loss compensation.
