11.2 Oscillation controlled by synchronized actions (OSCILL)

Description
1. Define oscillation parameters
The parameters for oscillation should be defined before the movement block containing
the assignment of infeed and oscillating axes and the infeed definition (see
"Asynchronized oscillation").
2. Define motion-synchronized actions
The following synchronization conditions can be defined:
Suppress infeed until the oscillating axis is located within a reversal area
(ii1, ii2) or at a reversal point (U1, U2).
Stop oscillation motion during infeed at reversal point.
Restart oscillation movement on completion of partial infeed. Define
start of next partial infeed.
3. Assign oscillating and infeed axes as well as partial and complete infeed.
Define oscillation parameters
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.
Note
Before oscillation starts, the synchronization conditions must be defined for the behavior of
the axes.
Define infeeds: POSP
POSP[infeed axis] = (End pos, partial length, 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 two equal steps (default setting).
Mode = 1 All partial infeeds are of equal size. They are calculated from
the complete infeed.
