Date: August 2005 Ref: CPAG 2005-08-002
The purpose of this Product Service Advisory is to inform you of a potential issue that exists with the following communication adapter and firmware version:
Communication Adapter |
Series Level(s) / Firmware Version(s) |
20-COMM-E |
Series B / Firmware Version 3.001 |
This Product Service Advisory explains the issues and the steps being taken to correct the issue. Due to the nature of the problem, this effort has been assigned a Type II Mandatory Product Service Advisory.
Problem Description
When a 20-COMM-E DPI EtherNet/IP adapter is installed in a PowerFlex 700S drive, or in a PowerFlex 700 drive with the Vector Control option operating at a DPI data rate of 500 kbps, intermittent communication faults may occur.
Faults codes that may be exhibited by the specific drive are:
Drive |
Fault |
PowerFlex 700S |
F53 – [ DPI Loss Port 5] F59 – [Net Loss DPI P5] |
PowerFlex 700VC |
F75 – [Port 5 Adapter] F85 – [Port 5 DPI Loss] |
Drive faults are more likely to occur when the 20-COMM-E adapter is configured to use Datalinks. When the fault occurs, the 20-COMM-E adapter will go into flash mode, become inoperable, and its MOD and NET A LEDs will simultaneously flash red. To clear the fault, the user must power cycle or reset the drive.
