Hello,

depending on the framesize of the G130 it can contain 1 to 3 powerblocks.
The inverter components are located on the powerblocks, so depending on the requested power a powerblock can support 1 to 3 output phases.

Nevertheless we are recommending to change all powerblocks of the drive.
Because if one is broken, it could also affect the other one and weakening it, so it could be broken during the next high load operation.
