Goodrive20-UL Series VFD
Fault tracking
-105-
Storage time
Operational instruction
Less than 1 year
No charging operation is required.
1 to 2 years
The VFD needs to be powered on for 1 hour before the first
running command.
2 to 3 years
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.
More than 3 years
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 of using power surge to charge for the VFD:
The right selection of power surge depends on the supply power of the VFD. Single phase
220V AC/2A power surge applied to the VFD with single/three-phase 220V AC as its input
voltage. The VFD with single/three-phase 220V AC as its input voltage can apply Single phase
220V AC/2A power surge (L+ to R and N to S or T). All DC bus capacitors charge at the same
time because there is one rectifier.
High-voltage VFD needs enough voltage (for example, 460V) during charging. The small
capacitor power (2A is enough) can be used because the capacitor nearly does not need
current when charging.
6.1.3.2 Electrolytic capacitor replacement
Read and follow the instructions in Chapter 1 "Safety precautions".
Ignoring the instructions may cause physical injury or death, or damage to
the equipment.
The electrolytic capacitor of the VFD must be replaced if it has been used for more than
35,000 hours. For details about the replacement, contact the local INVT office or dial our
national service hotline (400-700-9997).
6.1.4 Power cable
Read and follow the instructions in Chapter 1 "Safety precautions".
Ignoring the instructions may cause physical injury or death, or damage to
the equipment.
