System Feature Identified as of PowerFlex 525 Drive Firmware Revision 5.001
System Feature identified as of PowerFlex 523 Drive Firmware Revision 3.001

Currently on the PowerFlex 520-series drive there is no visible indication to a local user that the drive is in an Auto-Restart countdown sequence, which automatically restarts the drive when the sequence is completed.

To enhance drive operation and provide the greatest level of safety, PowerFlex 525 Drive Firmware Revision 5.001 and PowerFlex 523 Drive Firmware Revision 3.001 include another digital output enum option (Option 31) which energizes the output if the drive is performing an Auto-Restart countdown sequence.

This output should only be energized when the drive is actually counting down to a pending re-start. If the drive faults on F033 (Auto Rstrt Tries), the output should not be active.

Option 31 “AutoRst Ctdn” is added to the following parameters:

• t069 [Opto Out1 Sel]
• t072 [Opto Out2 Sel]
• t076 [Relay Out1 Sel]
• t081 [Relay Out1 Sel]

Parameters t069, t072, and t081 are applicable to PowerFlex 525 drives only.

Corrected: PowerFlex 525 Drives Firmware Revision 5.001
Corrected: PowerFlex 523 Drives Firmware Revision 3.001

When parameter A557 [Out Ph Loss En] is set to 1 “Enable”, the drive will detect loss of output phase current in one or all of its output phases. This is usually caused by failure in the motor winding, cable or operation of switching device which interrupts motor current. It should be fast enough to detect current loss within a quarter cycle of the output frequency and yet resistance to false alarm cause by noise or interference. In any case, detection time shall not be more that one second. Loss of all three phase current should be detected during DC injection.

Also, parameter A576 [Phase Loss Level] is added to adjust the sensitivity of the output phase loss detection.

A576 [Phase Loss Level]

(With FRN 5.xxx and later.)
(With FRN 3.xxx and later.)

Output Phase Loss Level. Sets the threshold level which is used to determine an output phase loss condition.

Each motor phase must exceed this value. Decreasing this parameter's value lowers sensitivity.
