PowerFlex 700S Drives with Phase II Control
High-Speed Analog and Digital I/O execute in 0.5 ms or less to provide
fast response and fast capture for registration information and position
data. Output relays, optically isolated and differentially isolated I/O are
supplied.
Inertia Adaptation stabilizes inertia disconnect due to gear boxes or
flexible couplings. It also provides broadband resonance compensation,
allowing up to 4x improvement to speed regulator bandwidth.
An Enhanced Process Loop executes six times faster than previous
loops, providing greatly improved dynamic response in tension control
applications.
The Control Loops within each drive are Synchronized. In addition, the
control loops for all drives on SynchLink are synchronized within micro-
seconds. This provides exceptional link coordination and tracking for
critical applications.
The Enhanced Bus Regulator reacts four times faster than previous
products, providing quicker stops without over-voltage issues and
outstanding performance in other regenerative applications.
