PowerFlex 700S Phase II Control
Digital Current Regulator outperforms
older style analog regulators in speed,
repeatability and drift.
Negative Feed Forward reduces or
eliminates overshoot during step speed
changes. Helpful in preventing backup
during stopping.
Coarse-to-Fine interpolation for
DriveLogix Motion, direct positioning for
precise control and point-to-point for
indexing are all features of the Integral
Position Loop. The loop easily handles
applications such as simple indexing and
electronic line shaft.
Advanced Edge-to-Edge Algorithms and
pulse position averaging provides
extremely accurate speed measurement
and excellent performance at very low
speed.
Servo Lock compensates for lost position
during step loads to the velocity regulator.
Offers optimum performance for draw
applications and others.
