6.1.3 Capacitor
6.1.3.1 Capacitor reforming
If the VFD has been left unused for a long time, you need to follow the instructions to reform
the DC bus capacitor before using it. The storage time is calculated from the date the VFD is
delivered.
No charging operation is required.
The VFD needs to be powered on for 1 hour before the first
running command.
Use a voltage controlled power supply to charge the VFD:
Charge the VFD at 25% of the rated voltage for 30 minutes, and
then charge it at 50% of the rated voltage for 30 minutes, at 75%
for another 30 minutes, and finally charge it at 100% of the rated
voltage for 30 minutes.
Use a voltage controlled power supply to charge the VFD:
Charge the VFD at 25% of the rated voltage for 2 hours, and then
charge it at 50% of the rated voltage for 2 hours, at 75% for
another 2 hours, and finally charge it at 100% of the rated voltage
for 2 hours.
The method for using a voltage controlled power supply to charge the VFD is described as
follows:
The selection of a voltage controlled power supply depends on the power supply of the VFD.
