Automatic Device Configuration for PowerFlex® Drives
What is ADC?
PowerFlex® 520 series and PowerFlex 750 series drives and peripherals with RSLogix® 5000 v20 controllers and above, support Automatic Device Configuration (ADC).
This means that your Logix controller can use ADC to automatically download parameters to the drive and peripherals when a configuration signature change is detected and/or a drive is replaced.
When the drives are installed on an Ethernet network with Stratix® managed switches, the switch can act as a DHCP server to provide the correct IP address on the following drives:
- PowerFlex 755 drive with embedded EtherNet/IP port
- PowerFlex 753 drive with the dual port EtherNet/IP adapter 20-750-ENETR
- PowerFlex 525 Embedded EtherNet with BOOTP
- PowerFlex 525 and 523 drive with dual port EtherNet/IP adapter 25-COMM-E2P with DHCP.
With ADC and other component features, the system will:
- Serve out the IP address for the replacement drive from the EtherNet/IP managed switch.
- Automatically verify or flash the firmware of the drive and peripherals, to ensure compatibility with your configuration.
- Automatically download the drive and peripheral as commissioned parameters.
Benefits of Automatic Device Configuration include:
- Simplify the drive replacement process to just replacing hardware and rewiring – no configuration needed.
- Reduced the possibility for programming errors or downloading the wrong config file.
- Restricted access to parameter changes, as the Logix controller owns the drives configuration
- Spare drives don’t need replacing or manually flashing to the correct firmware of drives and peripherals.
Things to be aware of:
There are some rules for ADC to complete successfully:
- A replacement drive must meet all firmware electronic keying requirements for ADC to complete successfully.
- Firmware must be loaded into Firmware Supervisor if required to automatically resolve firmware version incompatibility.
- Replacement drives must have an identical configuration of port hardware.
- The Safe Speed Monitor card must always be in Program mode before it is configured by ADC.
