Selection Notes
Selection notes specific to VFDs:
- Match the drive to the motor and application first (torque profile, overload class, braking needs) — see the motor selection workflow.
- Network option cards vary by family; confirm the exact protocol/card combination, not just the brand.
- Harmonics, EMC filtering, and cable-length limits are family-specific — check the application guide for the actual model.
- Commissioning guidance lives at VFD commissioning.
