Description
Assignment to
Keypad
Input
1
Reset
Sets the internal differential counter and the analogue
correction signal to zero. The cutting roll drive runs
solely in analogue synchronization (open loop control)
whilst activated
yes
yes
2
Start
Start of the automatic cutting procedure.
The unit cuts automatically to preset cutting length.
When this command is not set, the cutting roll is held in
its home position (closed loop position control). The
cutting roll can be moved into forward and reverse
direction by use of the inputs “Jog forw” and “Jog rev”.
yes
yes
3
Immediate
Cut
This command will immediately start the cutting roll for
a cutting cycle, independent on what the actual length
is. The subsequent cut will correspond to the preset
length again, unless another Flying Cut will be triggered
again. This function e.g. allows the operator to cut out
bad parts of the material. An immediate cut can also be
performed when the material is in standstill or when
Start command is reset.
yes
yes
4
Homing
Starts a homing cycle and moves the knife to a defined
home position. Within a homing cycle the cutting roll
moves forward till the cutting pulse appears. Then it
moves on to the home position.
Before starting the automatic cutting operation, we
recommend performing a homing cycle if the cutting roll
is not yet in its home position.
yes
yes
5
n.a.
no
no
6
Cutting
Pulse
Sensor input for the cutting pulse. For definition of the
knife position, the controller needs one index pulse with
every cut, which can be generated either by a remote
sensor or from the marker pulse of an HTL encoder.
no
yes
