• Checking the inverter and converter modules
<Preparation>
1) Disconnect the external power supply cables (R, S, T)

and motor cables (U, V, W).
2) Prepare a meter. (Use 100
Ω
range.)
<Checking method>
Change the polarity of the tester alternately at the inverter terminals R, S, T, U, V, W, P and N

, and check for continuity.
Note: 1. Before measurement, check that the smoothing capacitor is discharged.
2. At the time of continuity, the measured value is several to several ten’s-of ohms depending on the
module type, circuit tester type, etc. If all measured values are almost the same, the modules are
without fault.
