In this video; we discuss common alarms and failures with a VM3 spindle drive as well as share our tips to help you troubleshoot these alarms and failures. We also discuss some common causes to these failures such as,

  1. F-000: Winding Selection Contactor Failure - 
    • Bad contactor (HV-75APx(S), HV-150APx(S), or HV-200APx(S)) [x denotes revision of contactor with 4 being the most recent. S suffix is attached to end of contactor model number if plastic cover is installed to contactor.]
    • Control board failure
  2. F-100: Inverter Output Overcurrent
    • Failed output inside drive
    • Weak motor insulation (low megaohms to ground)
    • Weak cable insulation
  3. F-300: Input Overcurrent
    • Failed input inside drive
    • Failed current detection circuit
