Description: Setting to activate the "DC link capacitor forming" function.
This value also defines the forming duration.
The function is deactivated with p3380 = 0.
Recommendation: Recommended forming duration depending on the storage time:
1 - 2 years: p3380 = 1 hour
2 - 3 years: p3380 = 2 hours
>3 years: p3380 = 8 hours
Dependency: The "DC link capacitor forming" function can only be executed when commissioning the power unit (p0010 = 2). The
function is automatically deactivated (p3380 = 0) once commissioning has been exited (p0010 = 0).
Procedure when forming:
1. Activate power unit commissioning (p0010 = 2).
2. Activate forming (p3380 > 0, value, see recommendation).
3. Switch on the drive unit (p0840 = 0/1 signal).
4. Wait for forming to be completed (r3381 = 0).
5. Exit power unit commissioning (p0010 = 0).

NOTICE
If drive units are not commissioned within 2 years after their original manufacture, then the DC link capacitors must be
reformed before use. If this is not done, then the units could be damaged in operation.
Note
The "DC link capacitor forming" function can only be activated online in the drive unit.
If switched off while forming is active, the remaining time (r3381) is lost, and forming must be repeated for the full
forming time. If the forming duration is changed, then forming starts again from the beginning.
