IP Address and Gateway Address anomalies (LGX00163759/LGX00173005)

Corrected:

• PowerFlex 527 Drives Firmware Revision 1.008

Known anomaly first identified as of PowerFlex 527 Drives Firmware Revision 1.006

With firmware revision 1.007 or earlier:

• It is possible to enter identical values for the IP address and gateway address by using the keypad. This is an illegal IP address configuration for the PowerFlex 527 drive because the drive does not have the functionality or capability of an independent router and gateway.
• It is possible to change some of the IP configuration octets on the LCD display but, after a power cycle or after leaving and returning to the IP configuration pages, the drive reverts to the original value for the first three octets and retains the new value for the last octet.

With firmware revision 1.008 or later, you can change the IP configuration without any limitations to the IP configuration octet (parameters). You must enter a valid IP configuration and cycle power to the drive for the new IP configuration to take effect. If an illegal IP configuration exists upon power up, for example, if the IP address and gateway address are identical, the drive faults and exhibits INIT FLT M22 – ILLEGAL ADDRESS on the display and the IP address configuration changes to DHCP.

Change in keypad and webpage display (LGX00200090)

Corrected:

• PowerFlex 527 Drives Firmware Revision 1.008

Known anomaly first identified as of PowerFlex 527 Drives Firmware Revision 1.006

Shunt utilization data on the keypad and webpage always shows zero (0).

With firmware revision 1.008, shunt utilization is no longer shown on the keypad and webpage.  In addition, Output Current is now displayed as Output Curt 0.0 with a value in Amps RMS.  Refer to motion attribute 601 for more information.

Incorrect VelocityLockStatus bit behavior (LGX00171746)

Corrected:

• PowerFlex 527 Drives Firmware Revision 1.008

Known anomaly first identified as of PowerFlex 527 Drives Firmware Revision 1.006

Once the ActualSpeed reached or surpassed the Velocity Limit, the “Axis.VelocityLockStatus” tag / bit in Logix Designer stayed at 1 instead of changing to 0. 

Intermitted M28 faults or Safe Torque Off events occur (LGX00194147, LGX00194148, LGX00194596, LGX00201704)

Corrected:

• PowerFlex 527 Drives Firmware Revision 1.008

Known anomaly first identified as of PowerFlex 527 Drives Firmware Revision 1.006

The PowerFlex 527 drive’s internal safety data integrity check leads to an unexpected close and re-open of its safety connection.

Incorrect motor capacity decay model (LGX00194295, LGX00195436)

Corrected:

• PowerFlex 527 Drives Firmware Revision 1.008

Known anomaly first identified as of PowerFlex 527 Drives Firmware Revision 1.006

The implementation of the motor capacity decay model for the PowerFlex 527 drive is inconsistent when compared to the PowerFlex 750 Series drive.

With firmware revision 1.008, the drive’s motor capacity decay model is updated to be in-line with the PowerFlex 750 Series drive.
