CIP Motion Support for IPM Motor Control via Drive NV

System Feature Identified as of PowerFlex 755 Drive Firmware Revision 9.001

This revision of drive firmware allows customer to use the Drive NV functionality, to control Interior Permanent Magnet (IPM) motors in CIP Motion mode. This can be accomplished by commissioning the drive in standalone or IO mode. The next step is to connect the drive to the controller in CIP motion mode. In RSLogix or Studio 5000, the motor selection is set to Drive NV. The Drive NV selection enables the controller to read the motor and tuning settings from the drive for use in CIP Motion.

 

Corrected Anomalies in This Release

This release corrects the following anomalies.

Option Card Fault Condition with a 900 Level Drive Exception

CORRECTED with PowerFlex 755 Drive Firmware Revision 9.001

CORRECTED with PowerFlex 753 Drive Firmware Revision 9.001

When the drive experiences a 900 level exception, select PowerFlex 750-Series option cards remain in the last known state and may not fault. The last known state of the option card may differ from the default or startup state. This revision of drive firmware will fault the option card when the drive experiences a 900 level exception therefore making the behavior consistent for all drive status conditions previously mentioned.

 
PowerFlex 755 High Power Thermal Detection for Blower

CORRECTED with PowerFlex 755 Drive Firmware Revision 9.001

This revision of drive firmware changes the behavior of the thermal model, for all high power drives frames 8… 10, in conditions where the main blower is in a slowed or stopped condition. Under this operating condition the thermal trip and fault limits are adjusted to appropriately account for the changes in the blower fan speed.

 

Known Anomalies from Previous Releases

These anomalies are from previous releases but are still known in this release.

Feedback Selection

Known Anomaly First Identified as of PowerFlex 755 Drives Firmware Revision 3.004

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:

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

Persistent Stop Command with Profile Message Fault Action

Known Anomaly First Identified as of PowerFlex 755 Drives Firmware Revision 8.001

Known Anomaly First Identified as of PowerFlex 753 Drives Firmware Revision 8.001

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.

 
Saving Parameters Using DriveExplorer

Known Anomaly First Identified as of PowerFlex 755 Drives Firmware Revision 8.001

Known Anomaly First Identified as of PowerFlex 753 Drives Firmware Revision 8.001

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.

 
Support for Changing Permanent Magnet Direction Test Current

Known Anomaly First Identified as of PowerFlex 755 Drive Firmware Revision 2.011

Known Anomaly First Identified as of PowerFlex 753 Drive Firmware Revision 7.001

You cannot change the level of current used during the direction test on a permanent magnet motor while in Integrated Motion on EtherNet/IP (CIP Motion) mode. It is set at 10%. If the system requires more than 10% to turn the motor, it will fail to perform the test.

 
Delta Junction Temp at Zero Speed

Known Anomaly First as of PowerFlex 755 Drive Firmware Revision 2.011

The protection algorithms in frame 8 drives create false 168 “PWM Freq Reduced” exception events when running at zero speed. These can occur when the drive is first energizing the motor and establishing motor flux.

 
Diagnostic Item and Parameter Values Affected by Flash from Version 1 to Version 6

Known Anomaly First Identified as of PowerFlex 755 Drive Firmware Revision 3.004

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.

 
Missing Error When Drive NV Selected in Integrated Motion Mode

Known Anomaly First Identified As of PowerFlex 755 Drive Firmware Revision 3.004

This anomaly affected customers using Integrated Motion on EtherNet/IP (CIP Motion). If you attempted to use Drive NV when configuring the motor on a motion axis with a PowerFlex 755, the drive would not return the appropriate error. This feature is not currently supported in the PowerFlex 755.

 
CIP Motion Axis Inhibit F927 Event

Known Anomaly First Identified as of PowerFlex 755 Drive Firmware Revision 8.001

The drive may throw an F927 fault when an axis is inhibited. If this occurs, the drive will shut down allowing the motor to coast. The status LED will blink 27 times, pause, then repeat. If this occurs, cycle power to the drive to clear the fault.

 
F918 Exception Events

Known Anomaly First Identified as of PowerFlex 755 Drive Firmware Revision 6.004

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.
