Troubleshooting the FlexPak 3000 Drive 13-7
F00065 SELF TUNING FAULT Speed unstable.
Possible causes:
•
CML not properly tuned before speed loop.
• Tachometer or encoder feedback device connected incorrectly.
F00066 SELF TUNING FAULT SELF TUNE STABILITY (P.219) is too low.
Possible causes:
• Specified stability is less than that calculated by CML self-tuning. Use 50
or more.
F00067 SELF TUNING FAULT SELF TUNE STABILITY (P.219) is too low.
Possible causes:
• Specified stability is less than that calculated by CML self-tuning. Use 75
or more.
F00089 to
F00099 SELF TUNING FAULT Fatal self-tuning fault occurred.
Possible cause:
• Self-tuning was unable to complete. Tune manually.
F00100 MAIN CONTACTOR DID
NOT OPEN
The main ( FN ) contactor did not open following a run or jog request. If a
dynamic braking kit is used, the dynamic braking auxiliary contact is wired
in series with the
FN auxiliary contact.
Possible causes:
• Disconnected, loosely connected, or damaged FN , FN auxiliary, dynamic
braking, or dynamic braking auxiliary wiring.
•
FN , FN auxiliary, dynamic braking, or dynamic braking auxiliary contactor
failure.
• Disconnected, loosely connected, or damaged main contactor or
dynamic braking control wiring (
MCR or DBCR ).
F00200 POWER FAILURE The power supply input voltage momentarily went below tolerance.
Possible causes:
• AC line voltage dip.
• Disconnected, loosely connected, or damaged J7 ribbon cable or power
supply input wiring
