a.
If you have more than one tool but only one single cutting pulse per revolution of the cutting
roll, then set register “Cuts per Rev.” to the number of cuts performed by one revolution of the
cutting roll. The controller will generate the missing cutting pulses internally.
Example:
Two cuts per revolution but only one cutting pulse
→
“Set Cuts per Revolution“ = 2
b.
If you perform several cuts per revolution of the cutting roll and each cut generates its own
separate cutting pulse, then proceed as follows:
Set register “Cuts per Revolution” to 1.
Do not set register “Circ. Cutter” to the real circumference of the cutting roll but set it to
the partial circumference between two tools.
Also set register “PPR Cutter” to the number of pulses between two tools at the cutting
roll.
Example:
Two cuts per revolution and also two cutting pulses
→
Set “Cuts per Revolution“ = 1,
“Circ. Cutter” = ½ cutting roll circumference and
“PPR Cutter” = ½ number of pulses per revolution.

Range Default
F02.015 Vmax / V line:
This setting is important only when the range of cutting lengths
includes lengths shorter than the roll circumference, so the roll
must accelerate between two cuts. The register sets the maximum
speed ratio between the circumferential roll speed and the line
speed that the drive will take when required.
This means, whenever you cut shorter length, it is necessary the
slave drive can at least run double line speed. The higher the ratio,
the shorter the minimum length you can cut. It is important to know
that this ratio setting does not refer to the maximum line speed, but
to the real line speed you use when cutting short length. You are
free to reduce your line speed with shorter length preset and i. e.
set this register to 8. But then you must be sure that the cutter drive
can really run 8 times the line speed you actually use for your
shortest length. In general, setting 8 is recommended.

F02.016 Home Window:
Sets a window scaled in length units around the home position of
the cutting roll, which is located opposite to the centre point of the
synchronous zone.
The output “Home” indicates that the cutting roll position is inside
this window.
