PowerFlex 700 Technical Data
4 20B-TD001F-EN-P
Outstanding Control and Performance
Multiple motor control algorithms allow performance matched to the
application need:
• Volts/Hertz for simple Fan and Pump applications.
• Sensorless Vector for high torque production over a wide speed range.
• Vector for outstanding torque regulation and excellent low speed/zero
speed performance (w/Vector Control cassette).
The PowerFlex 700 drive's Vector Control uses Allen-Bradley's patented
Force™ Technology which provides excellent low-speed performance -
whether it is operated with or without feedback. While this industry-leading
control provides the highest level of drive performance, it is as easy to use as
any general purpose drive available.
Drives Features
• Fast-acting Current Limit and Bus Voltage Regulation result in maximum accel/decel without tripping.
• High speed analog inputs improve drive response to torque or speed commands.
• Programming flexibility allows parameters to be linked within the drive.
• Flying Start delivers smooth and instantaneous connection into rotating loads, regardless of commanded direction,
without the need for any speed feedback.
• Integral Process PI Control can eliminate the need for a separate process loop controller.
• Inertia Ride-Through offers tripless operation during a prolonged power outage by using the rotating energy stored in
high inertia, low-friction loads.
• Position Indexer/Speed Profiler uses a 16 step indexer to provide point-to-point positioning or velocity profiling
based on encoder counts, digital inputs, parameter levels or time.
• TorqProve™ assures control of the load when transferring control between the drive and a mechanical brake.
• Speed Regulation - Open Loop or Closed Loop
- Slip Compensation delivers a minimum 0.5% speed regulation without feedback hardware.
- Droop allows drives to load share without fighting each other.
- Encoder Feedback provides up to 0.001% speed regulation for the tightest application requirements.
• Torque Regulation - Open Loop or Closed Loop
- Open Loop torque regulation provides ±5% regulation.
- Encoder Feedback provides ±2% regulation and the ability to hold full load at zero speed.

Description
✔✔✔ (Unconnected Messaging) permits other network devices (e.g. PanelView™) to communicate directly to a drive without routing the commu-
nication through the network scanner.
✔✔✔✔✔ ✔✔Adapter Routing - Plug PC into one drive and talk to all other Allen-Bradley drives on same network, without being routed through network
scanner.
✔✔✔✔✔✔✔✔✔✔✔✔Access to 100% of all parameters over the network.
✔✔✔ ✔ AutoBaud capability makes initial connections less problematic.
✔ Change of State significantly reduces network traffic by configuring control messages to be sent only upon customer defined states. Very
flexible configuration for each node (Example: “reference must change by more than 5%”).
✔✔ Peer Control provides master-slave type control between drives, where one or more slave drives (consumers) can run based on the status of
a master drive (producer), which can also significantly reduce network traffic.
✔ ADR (Automatic Device Replacement) saves significant time and effort when replacing a drive, by allowing the scanner to be configured to
automatically detect a new drive and download the required parameter settings.
✔✔✔✔✔✔✔✔✔✔✔✔Flexible Fault Configuration - Adapters can be programmed to take fault based actions as ramp to stop, coast-to-stop and hold last state,
as well as send user configurable logic control and speed reference values. In addition, different actions can be taken based on whether the
network experienced a serious problem (broken cable etc.) versus network idle condition (PLC set to “Program”).
