Issue:
Time before the capacitors from a Process Drive need to be reformed by the storage without being energized.

Product Line:
Altivar Process Drives

Environment:
All

Cause:
Some customers have a need to let a drive sit for long periods of time without use

Resolution:
For long storage periods it is recommended to supply the drive with line voltage at least once per year for one hour (if possible). 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.

NOTICE: REDUCED CAPACITOR PERFORMANCE

• 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 equipment damage.

If the specified procedure cannot be performed without a Run command because of internal mains contactor control, perform this procedure with the power stage activated, but the motor being at standstill so that there is no appreciable mains current in the capacitors.
