Appendix H — Static Checking
Static Checking
Static checking tests the integrity of the power-carrying components (diodes, capacitors
and IGBTs) within the drive assembly. Performing these static checks ensures that no
damage occurred during shipping or installation that could cause a failure when the drive
is powered.
Make sure there is no power to the drive before proceeding with any of the static checks.
After checking each set of terminals, zero out the multimeter by touching the metal tips of
the red (positive) and black (negative) leads to each other.
Note: Set the multimeter to the diode function, and check each power terminal
consecutively with each DC bus terminal as indicated in Table 7.
Table 7: Static Checks of Converter
Note: Set the multimeter to the diode function, and check each motor terminal
consecutively with each DC bus terminal as indicated in Table 8.
