REAL LIFE SOLUTIONS IN THE PLANT: Practice safe drive repairs! If you spent part of your already tight budget on drive repairs, or even for an expensive NEW drive, protect your investment! You can do this by troubleshooting your equipment that the drive came out of. When troubleshooting, look for problems that may have caused the damage in the first place.
This situation is not rare and is frequently the cause of repeat problems. And the cause of repeat repair expenses! The pictured Infranor drive repair p/n SMT-BD1/1A-220/12-W-T-BS has damage in the brake circuit including a blown FET and some damaged traces.
What CAUSED this damage? The primary damage to this drive appears to have been caused by an external issue possibly with the brake resistor in the rack that this drive (and a matching one with the same damage) go into. The rack and external brake circuits need to be checked for problems BEFORE REINSTALLING these drives. The ACS repair services included replacing FET, repairing trace damage, replacing high voltage capacitors, installing a new ipm output module as well as a thorough cleaning and testing.
Save yourself a headache AND unnecessary repair expenses by checking your equipment BEFORE reinstalling a freshly repaired unit. If the damage is done and you need servo drive repairs we can help. #fixit #repaironcetesttwice #safety
