Brief Check of POWER MODULE

Usually, they are in a state of being short-circuited if they are broken.

Measure the resistance in the following points (connectors, etc.).

If they are short-circuited, it means that they are broken.

1. Check of DIODE MODULE

L1 - P1 , L2 - P1 , L3 - P1 , L1 - N1 , L2 - N1 , L3 - N1

2. Check of DIP-IPM

P2 - U , P2 - V , P2 - W , N2 - U , N2 - V , N2 - W

Note: The marks L1 , L2 , L3 , N1 , N2 , P1 , P2 , U , V and W

shown in the diagram are not actually printed on the board.
