230V FX Series Positioning Drive Reference Manual
Figure 93: Example 1, Compound Index Profile
The drive will continue at that velocity until it approaches the programmed distance of Index
#2, then decelerate at the Index #2 deceleration rate to the Index #3 programmed velocity. It
will continue at that velocity until it approaches the programmed distance of Index #3, at
which time it will decelerate at the Index #3 deceleration rate and stop.
When using multiple compound indexes within the same program, all compound index
directions must be the same. The direction of movement is set by the first of the compound
indexes and is not scanned again until the next index is initiated that is outside the compound
ones.
Example 2:
This example is similar to #1, except in this compound index the drive will accelerate instead
of decelerate at the end of each individual index.
