11-10 Programming Manual, 03/2006 Edition, 6FC5398-2BP10-1BA0
Functions
You can implement the following functions with the language resources described in detail
below:
1. Infeed at reversal point.
2. Infeed at reversal area.
3. Infeed at both reversal points.
4. Stop oscillation movement at reversal point.
5. Restart oscillation movement.
6. Do not start partial infeed too early.
The following assumptions are made for all examples of synchronized actions presented
here:
• Reversal point 1 < reversal point 2
• Z = oscillating axis
• X = infeed axis
Note
For more details, see the "Motion-synchronous actions" section.
Assign oscillating and infeed axes as well as partial and complete infeed
Infeed in reversal point range
The infeed motion must start within a reversal area before the reversal point is reached.
These synchronized actions inhibit the infeed movement until the oscillating axis is within the
reversal area.
The following instructions are used subject to the above assumptions:
Reversal point range 1:
WHENEVER $AA_IM[Z]>$SA_OSCILL_RESERVE_POS1[Z]+ii1 DO $AA_OVR[X] = 0
Whenever
greater than
then
the current position of oscillating axis in the MCS is
the start of reversal area 1
set the axial override of the infeed axis to 0%.
Reversal point range 2:
WHENEVER $AA_IM[Z]<$SA_OSCILL_RESERVE_POS2[Z]+ii2 DO $AA_OVR[X] = 0
Whenever
less than
then
the current position of oscillating axis in the MCS is
the start of reversal area 2
set the axial override of the infeed axis to 0%.
