wobble function
The wobble function is used for the
traverse function on a textile winder.
VLT 2800 operates a motor, which
turns a grooved drum. During
winding, the grooved drum places
the thread in the correct position on
the bobbin, in a diamond pattern.
If the traverse (grooved) drum was
operating at a constant speed, the
thread would tend to cross at the
same position for each pass, which
would give a very loose and less
compact winding on the bobbin.
Precise stop
Conventional units rely on a periodic
scan of the digital inputs, which
initiates the Stop command. This can
result in uneven delays while the
drive scans all the other parts of the
program taking up to perhaps 10 ms.
This is a disadvantage in typical
packaging applications.
For a conveyor operating at a speed
of 1 metre/second, that gives a
deviation of ±10 mm. In the VLT®
2800, the Stop command is an
interrupt rather than part of the scan.
The repeating precision is improved.
The deviation is only ±1 mm in the
example used above.
Counter Precise Stop
After the start signal is received, the
VLT® 2800 operates until the user
programmed number of pulses is
seen at terminal 33. A Stop signal is
generated and the normal stop ramp
is used. The counter stop signal is
then re-armed and ready again for a
new start command. The pulse input
is designed to handle 24 V push-pull
pulses from an encoder with up to
1024 ppr. The maximum pulse rate is
67,600 Hz.
