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 6SL3055-0AA00-5CA2 SINAMICS SMC30 is a Sensor Module Cabinet that connects incremental TTL/HTL encoders, combi SSI encoders with incremental tracks, or SSI-only encoders to a SINAMICS S120 drive system. It has a 30 mm overall width and a net weight of 0.41 kg, and ships without a DRIVE-CLiQ cable.
This SMC30 variant does not include a DRIVE-CLiQ cable, so order the appropriate length separately when connecting it to a Control Unit or Motor Module. It accepts three encoder interface types, TTL/HTL incremental, combined SSI-plus-incremental-track, or SSI-only, so confirm which encoder protocol the connected motor or axis uses before specifying this module over a single-protocol sensor module.
External encoder feedback interfacing on SINAMICS S120 axes using TTL/HTL or SSI encoders mounted separately from the motor.
