The following is the list of test points on the DPM.
Table 21 - Test Points on Drive Processor Module
This table defines the states of LED D9 and D11 on the DPM board. D9 is used
for the Inverter side processor and D11 is for the Rectifier side processor. The
other two LEDs (D6 and D7) are the watchdogs for the Inverter and Rectifier
code respectively.
Table 22 - Description of D9 and D11 Function
Diagnostic Test Points on the DPM have a voltage output range of -5 to +5V.
