Known Anomaly First Identified as of PowerFlex 753 Drives Firmware Revision 5.001

The HIM startup on the PowerFlex 755 drive includes a feedback device selection step. Depending on the option modules installed, that step may first ask the user to choose a port, then a parameter. In some situations, the list of ports incorrectly shows multiple copies of 'Port 0 - PowerFlex 755' followed by the feedback port/module.

The incorrect behavior happens only under the following conditions:

• It is the first time that startup feedback selection has been run since flashing the drive.
• The feedback module is a dual encoder or UFB and no other option modules are installed.
• A reset to defaults of the drive NVS parameters has not been performed since the drive was last flashed.

When the incorrect port list appears, it is still possible to successfully select the feedback module port by following one of these methods.

• Scroll past the multiple copies of Port 0 to reach the desired feedback module.
• Press the Esc soft key to back up one screen, then select Feedback and press the Enter soft key to display the port selection screen a second time. This time the correct list will be shown.

In an application with the use of a PowerFlex 755 or PowerFlex 753 along with the 20-750-ENETR dual port Ethernet/IP module, a persistent stop command may appear in some cases. The action of disconnecting the Ethernet cable from the 20-750-ENETR module, which will result in the drive stopping, may follow with a nuisance fault action. This fault action previously noted is persistent communication of stop commands.

In an application with the use of a PowerFlex 755 or PowerFlex 753 along with the 20-750-ENETR dual port Ethernet/IP module, in which a user attempts to save all parameters using DriveExplorer® in some causes the save execution does not complete. When attempting to execute the save all parameters in DriveExplorer the software tool enters an infinite loop and does not progress through the save in some instances. To exit the loop, press the cancel button and check if the text file has been saved.

Known Anomaly First Identified as of PowerFlex 753 Drive Firmware Revision 5.001

The following internal diagnostic items may contain incorrect data after upgrading a PowerFlex 755 from revision 1 to revision 6 firmware: 2 [PBLT Pwrup Time], 3 [PBLT GatesOnTime], 4 [PBLT Mtr MW Hrs], 5 [PBLT Rgn MW Hrs] and 67 [PwrBd Pwr Cycles].

The following parameters may contain incorrect data after upgrading a PowerFlex 755 from revision 1 to revision 6 firmware: 13[Elapsed MWH], 14 [Elapsed kWH], 15 [Elapsed Run Time], 16 [Elpsd Mtr MWHrs], 17 [Elpsd Rgn MWHrs], 18 [Elpsd Mtr kWHrs], 19 [Elpsd Rgn kWHrs], 490 [HSFan ElpsdLife], 497 [InFan ElpsdLife], 503 [MtrBrngElpsdLife], 508 [MtrLubeElpsdHrs], 512 [MchBrngElpsdLife] and 517 [MchLubeElpsdHrs].

These values will affect the associated calculated “ remaining life ” parameter values and predictive maintenance events.

Known Anomaly First Identified as of PowerFlex 753 Drive Firmware Revision 6.004

When running in Flux Vector open loop mode for induction motor or Interior Permanent Magnet (IPM) motor mode, the drive may experience an F918 exception event when the motor accelerates through a 7 Hz operating frequency due to the simultaneous transition from a 2 to 4 KHz carrier frequency. This exception can be avoided by setting parameter 40 [Mtr Options Cfg] bit 9 – PWM FreqLock], which will keep the carrier frequency at 4 KHz.

Universal Feedback Board Module Does Not Annunciate Fault

Known Anomaly First Identified as of:

• PowerFlex 755 Drive Firmware Revision 12.001
• PowerFlex 753 Drive Firmware Revision 12.001

When the UFB is configured to use the SSI Full Digital Feedback Device, the UFB does not annunciate a fault when the SSI Full Digital is the signal is lost.
