Corrected: PowerFlex 525 Drives Firmware Revision 1.005

When a fault occurs, using the “Stop” key on the drive keypad to clear the fault may take more than one attempt.

The drive LCD display is unable to show Turkish, Polish, or Czech languages.

Important: This anomaly has been fixed in this firmware revision. However, due to a limitation of the LCD display, some of the characters for Turkish, Polish, and Czech languages will be modified.

When a “Start” command is sent to a drive using EtherNet/IP, sometimes the drive does not respond and the command needs to be resent.

If a Bulletin 1203-USB converter is used to interface with the DSI port on a drive that has an attached communication adapter, resetting the communication adapter using Connected Components Workbench™ software causes DSI comms to become unresponsive.

The firmware of an attached PowerFlex® 25-COMM-E2P adapter cannot be flashed through the drive.

Corrected: PowerFlex 525 Drives Firmware Revision 1.005

This anomaly applies to drives using the PowerFlex 25-COMM-E2P adapter in Multi-drive mode.

When the controller sends the parameter P053 [Reset to Defalts] command to the drive through the adapter, fault F081 “DSI Comm Loss ” can occur.

Corrected: PowerFlex 525 Drives Firmware Revision 1.005

When a drive is disconnected from EtherNet/IP and faults on F083 “EN Comm Loss”, resetting this fault can cause fault F114 “uC Failure ” to occur.

Corrected: PowerFlex 525 Drives Firmware Revision 2.003

Corrected: PowerFlex 523 Drives Firmware Revision 2.002

Known Anomaly Identified as of PowerFlex 525 Drives Firmware Revision 1.005

If the user's controller program holds the Start or Jog command bit active (1) in the drive’s logic command word, asserting a "Stop condition" will result in the drive stopping as expected. However, when the "Stop condition” is removed, the drive will run immediately if the Start or Jog command bit is still active (1).

PowerFlex 525 drive firmware revision 2.003 and PowerFlex 523 drive firmware revision 2.002 corrects this behavior. The removal of the Stop condition will no longer cause the drive to run (with Start or Jog bit active). A transition of the Start or Jog bit must now be initiated for the drive to run.

See Knowledge Base ID 603580 – Product Notice 2014-06-001 – PowerFlex 523/525 Start and Jog Bit Logic (201406001) for more details.

Corrected: PowerFlex 525 Drives Firmware Revision 2.002

Known Anomaly Identified as of PowerFlex 525 Drive Firmware Revision 1.005

When power is shut off, the drive will discharge any remaining power. During this period, resetting a drive fault may cause fault F105  C Connect Err ” to occur.

Corrected: PowerFlex 525 Drives Firmware Revision 2.003

When a fault is cleared by setting parameter A551 [Fault Clear] to 2 “Clear Buffer” or comm logic command 2002H Bit 3 to 1 “Clear Faults”, fault F105 “C Connect Err” occurs after the drive is power cycled.

This anomaly exists in firmware revision 1.005 and 2.002. It will cause the drive to not trigger fault F004 “UnderVoltage” before power off and causes fault F105 “C Connect Err” to occur after power up.

Firmware revision 2.003 corrects this anomaly so that when the drive is power cycled, fault F004 “UnderVoltage” should trigger before power off and no fault should occur after power up.
