Assignment of oscillating and infeed axes:
OSCILL
OSCILL[oscillating axis] = (infeed axis1, infeed axis2, infeed axis3)
The axis assignments and the start of the oscillation
movement are defined with the OSCILL command.
Up to 3 infeed axes can be assigned to an oscillating
axis.
Before oscillation starts, the synchronization
conditions must be defined for the behavior of the
axes.
Define infeeds: POSP
POSP[InfeedAxis] = (EndPosition, Part, Mode)
The following are declared to the control with the POSP
command:
•
Complete infeed (with reference to end position)
•
The length of the partial infeed at the reversal
point or in the reversal area
•
The partial infeed response when the end
position is reached (with reference to mode)
Mode = 0 The distance-to-go to the destination point for the last two partial infeeds
is divided into 2 equal steps (default setting).
Mode = 1 All partial infeeds are of equal size. They are calculated from the
complete infeed.
