Allen-Bradley PowerFlex 70 Enhanced Control User Manual

72 Position Indexer/Speed Profiler
Encoder Incremental with Velocity Override - This profile is the same as Encoder
Incr, but contains the “Velocity Override” function. During step 3 the “Vel
Override” bit was set. While active the [Step 3 Velocity] is multiplied by [Vel
Override]. In this example [Vel Override] is 150% causing the speed to be 450rpm
rather than 300.
Encoder Incremental w/Dwell and Velocity Override
End Hold Position – The drive holds the last position and stops the profile after
dwell time expires.
Encoder Absolute
– This is a move to an absolute position, which is referenced
from the home position. When started the drive ramps to the desired velocity in the
direction required, holds the speed, then ramps to zero speed at the position desired
within the tolerance window.
