If the drive was not connected to mains for an extended period of time, the capacitors must be restored to their full performance before the motor is started.
1- Procedure after a long time storage for the ATV312:
The capacitors after a long time storage can have issues. Following a storage time between 2 and 3 years:
- Use one AC supply variable connected between L1, L2 and L3
- Increase AC supply voltage to have:
- 25% of rated voltage during 30mn
- 50% of rated voltage during 30mn
- 75% of rated voltage during 30mn
- 100% of rated voltage during 30mn
2- Procedure after a long time storage for the ATV320:
- Apply mains voltage to the drive for one hour before starting the motor if the drive has not been connected to mains for the following periods of time:
- 12 months at a maximum storage temperature of +50°C (+122°F)
- 24 months at a maximum storage temperature of +45°C (+113°F)
- 36 months at a maximum storage temperature of +40°C (+104°F)
- Verify that no Run command can be applied before the period of one hour has elapsed.
- Verify the date of manufacture if the drive is commissioned for the first time and run the specified procedure if the date of manufacture is more than 12 months in the past.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
