Infranor SMT 100/05 720 Drive

The Infranor SMT 100/05 720 Drive is a digital brushless servo amplifier used to control high‑speed motor applications. Common failure points for this class of units include power‑rail degradation (especially the 48 V DC supply), overheating of the MOSFET bridge, overcurrent protection trips, and loss of communication on the fieldbus or Ethernet interface. Initial checks should verify that the input voltage is within spec and stable, inspect the board for burn marks or swollen capacitors, and review any logged error codes from the drive’s diagnostic port before proceeding to component‑level testing.[oss-gpt-20b] Post Comment
