PowerFlex DC Drive and Field Controller Technical Data
The PowerFlex DC Standalone Regulator
The PowerFlex DC Standalone Regulator (SAR) and Gate Amplifier products provide an integrated solution to control external DC power
modules. The SAR is a DC drive regulator that provides armature regulation, armature SCR gate signals and a regulated field supply. The SAR
field supply consists of a single-phase, two quadrant (non-reversing) full wave rectified bridge, available as 40 amps or 70 amps. The SAR
supports an AC line input voltage range of 230…690V AC and a field input voltage range of 100…460V AC.

Description
   
(Unconnected Messaging) permits other network devices (for example PanelView™) to communicate directly to a drive without
routing the communication through the network scanner.
    
Adapter Routing - Plug personal computer 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.
Flexible configuration for each node (Example: “reference must change by more than 5%”).
 
Peer Control provides master-slave type control between drives. With this feature, one or more slave drives (consumers) can run based
on the status of a master drive (producer). This feature can significantly reduce network traffic.

ADR (Automatic Device Replacement) saves significant time and effort when replacing a drive. The scanner can be configured to
detect a new drive and download the required parameter settings.
      
Flexible Fault Configuration - Adapters can be programmed to take fault-based actions, such as Ramp to Stop, and send user-
configurable logic control and speed reference values. The drive can take different actions that are based on whether the network
experienced a serious problem (broken cable, for example) versus network idle condition (PLC set to “Program”).
