d392 [RdyBit Mode Act]

(With PowerFlex 525 FRN 3.xxx and later.)
(With PowerFlex 523 FRN 3.xxx and later.)

Displays the value of A574 [RdyBit Mode Cfg].

A574 [RdyBit Mode Cfg]

Stop drive before changing this parameter.

(With PowerFlex 525 FRN 3.xxx and later.)
(With PowerFlex 523 FRN 3.xxx and later.)

Determines which Stop conditions causes the drive’ s Ready bit (Network Logic Status bit 1) to go low (0). A reset or power cycle is required after selection is made.         

(1) Condition is specific to PowerFlex 525 drives only.

Known Anomaly as of PowerFlex 525 Drives Firmware Revision 2.002

The loss of accuracy in the Autotune routine sometimes causes the value of parameter A496 [IR Voltage Drop] to be incorrectly configured. When this incorrect value is used, it causes parameters A484/A485 [Current Limit x] to not operate properly.

This anomaly exists in firmware revision 2.002 and 2.003. Once the current limit is reached and the drive’ s frequency is at 0 Hz, after a short time the drive faults on F064 “Drive Overload”.

Firmware revision 3.001 corrects this anomaly. The tuning accuracy is corrected and parameters A484/A485 [Current Limit x] now operate properly.

Corrected: PowerFlex 525 Drives Firmware Revision 3.001

Known Anomaly First Identified as of PowerFlex 525 Drives Firmware Revision 2.002

When the drive is commanded to Stop through Comms (Stop bit =1), the Ready bit goes low (0).

This anomaly exists in firmware revision 2.002 and 2.003. The addition of this Stop condition that affects the behavior of the Ready bit caused a change in functionality for some existing Logix programs.

Firmware revision 3.001 corrects this anomaly by adding two new parameters, d392 [Rdy Bit Mode Act] and A574 [RdyBit Mode Cfg]. These allows users to configure the Ready bit status.

For more information on the two parameters, see System Feature for Firmware Revision 3.001 “New Parameters for Configuring Behavior of Drive Ready Bit.”

Reserve AppView Parameter Group G9 is unused and has been removed.

Corrected: PowerFlex 525 Drives Firmware Revision 4.001

Known Anomaly Identified as of PowerFlex 525 Drives Firmware Revision 3.001

When using ADC (Automatic Device Configuration) in Studio 5000 or Connected Components Workbench, the function does not work. Additionally in Connected Components Workbench, a custom group created with firmware revisions 1.xxx or 2.xxx cannot be downloaded to a drive with firmware revision 3.001.

This anomaly exists in firmware revision 3.001.The removal of the reserve AppView Parameter Group G9 caused an incompatibility with firmware revisions 1.xxx and 2.xxx.

Firmware revision 4.001 corrects this anomaly. The reserve AppView Parameter Group G9 is restored. Firmware revision 3.001 is not compatible with firmware revision 4.001 and later.
