Appendix F Instruction of Drive Charging
Caution: If the drive is unused or stored in the storage over 1 year, the surface of
aluminum foil of electrolytic capacitor within the drive will be oxidized and
cracked causing the L and C value up. This is the common characteristics
of capacitor. Therefore, with directly applying the voltage and high current
to drive after the drive is placed for a long time, the drive may be damaged
due to the oxide film cracked.
A. If the drive is stored or non-used (no power ON) over 1 year, it is necessary to
charge the drive by autotransformer for 30 minutes from 0 volt to the half of drive
’s
rated voltage and then to apply drive rated voltage to charge the drive for another
30 minutes.
B. When charging the internal capacitor of drive, the wiring between autotransformer
and terminals (R/L1, S/L2) of drive is shown as below:
