In this video, we go over a quick static check procedure with the Magnetek 505 or 506 series inverters. Static checks can catch big issues with the drive’s inputs and outputs but keep in mind: even if a drive passes a static check, there can still be issues present.

  • Tools required
    • Digital Multimeter w/ diode checking functionality
    • Megohmmeter, if checking the motor as well
  • What to look for
    • Check for any leakage to ground from L1, L2, L3, T1, T2, and T3
    • Using the diode checking functionality of multimeter, verify output modules using method shown in video
  • Everything looks good, now what?
    • If all external factors check out, can still potentially be issues within drive unit. We recommend sending the unit in for further evaluation at this point.
