Issue:
Power Factor correction capacitors on the Altivar Variable Frequency Drives. 

Product Line:
Altivar Drives

Environment:
All models and serial numbers

Cause:
None

Resolution:
Schneider Electric does not recommend using power factor correction capacitors with variable frequency drives.  Capacitor banks in distribution systems with 6 pulse variable frequency drives may result in undesirable resonant currents.
