VFD vs Servo Drive: Key Differences
A side-by-side comparison of VFD and servo drive motor type, feedback, dynamic response, overload rating, cost, and applications for industrial engineers.
The Siemens 6SL3055-0AA00-5AA3 is a SINAMICS S120 SMC10 sensor module, a sensor board that evaluates a resolver signal for the S120 drive system. It weighs 0.41 kg and is supplied without a DRIVE-CLiQ cable, so a separate DRIVE-CLiQ cable is needed to connect it between the resolver wiring and the drive's Control Unit or Motor Module.
Use the SMC10 when the motor feedback device is a resolver rather than a sin/cos or EnDat encoder. The SME-series sensor modules in the S120 line-up are built for encoder feedback instead, so they are not interchangeable with a resolver-equipped motor. Confirm which feedback device is fitted to the motor before ordering, since mixing up a resolver-based motor with an encoder-only sensor module will leave the drive without valid position feedback.
