Issue: 
Troubleshooting a Altivar 58 with a blank display and will not power up.

Product Line: 
ATV58

Environment: 
All of the ATV58

Cause: 
DC bus is not charging, bad power board or MCB

Resolution:

  1. Check Mains voltage on L1 L2 L3, 
  2. Check DC bus voltage ( if this drive has a DC choke check to make sure its connected to PA and PO).
  3. Check the +24vdc and +10vdc power supplies.
  4. Power cycled  if needed  and see if the display comes back up. 

If no voltage on +24 or +10 then could be power board or control board issue. Unfortunately parts are obsolete so drive can be sent in for repair or unit can be replaced.

NOTE:  ATV58 drives have been obsolete since 2007.  No repair or replacement parts are available.  Review the application and installation to determine an appropriate replacement from our current offer.
