Pos. Rev.
and
Pos Interval Fwd/Pos Interval Rev
). These modes allow external equipment
to be triggered at exact position values.
Using the last three modes above, position triggering can be configured to be
unidirectional (
Trig Out Pos. Steps Fwd
or
Trig Out Pos. Steps Rev
) or bidirectional
(
Trig Out Pos. Steps Both
). In bidirectional mode the forward and reverse pulse
sequences can be configured separately. A cycle count setting (
Num. of Move Cycles
)
allows the uni- or bidirectional position triggering sequence to be repeated a number
of times.
Fig. 6.6 Position Steps Triggering
Example for a move from 0 to 2000 steps and back.
In forward direction: The first trigger pulse occurs at 1000 steps (StartPosFwd), the
next trigger pulse occurs after another 500 steps (PosIntervalFwd), the stage then
moves to 2000 steps.
In reverse direction: The next trigger occurs when the stage gets to 1200 steps.
Note that position triggering can only be used on one TRIG port at a time.
Note
In the
Trig Out Pos. Steps Fwd
mode, the
StartPos. Fwd
value must be reached in
the forward direction for the subsequent trigger sequence to be performed correctly.
If
StartPos. Fwd
is reached in the reverse direction, the initial trigger will still be
activated, but any subsequent sequence could be corrupted. Similarly,
StartPosRev
must be reached in reverse direction for the sequence to work correctly.
