SV670NT021I-INT is a 21 A class EtherCAT servo drive to assess for a high-inertia feed axis. Its current class comes from the manufacturer A01 ordering chart. Higher drive current does not automatically solve vibration: motor inertia, load ratio, coupling stiffness and control settings must be reviewed as a system.

Current and options follow the A01 ordering/selection chart. No single motor power is assumed; verify the complete motor pairing and peak-current duration. The online current entry differs; confirm before ordering.
Application selection
The online current entry differs from the catalogue. Make confirmation of the 21 A class and exact motor pairing an explicit supply requirement.
Will a larger drive remove mechanical resonance?
No. Resonance depends on stiffness, inertia and control settings. Increasing available current alone is not a complete remedy.
Installation and commissioning
Qualified personnel must use the exact-model manual for installation and commissioning. Apply lockout before physical inspection, retain project/parameter backups and never bypass protective functions.
