Frequently Asked Questions (FAQ)

Q: How does the SINAMICS S120 motor module integrate with existing automation systems?
A: The module connects via DRIVE-CLiQ to a SINAMICS S120 control unit, which interfaces with higher-level controllers through standard industrial protocols (PROFINET, PROFIBUS, EtherNet/IP). Verify control unit compatibility and available communication slots before ordering.

Q: What is the maximum motor power this single motor module can control?
A: Motor power capacity depends on the specific module designation (indicated by the order code). The 6SL3120-2TE21-0AD0 specification should be verified against motor nameplate ratings. Parallel module operation is possible for higher power requirements.

Q: What energy savings can be expected with SINAMICS S120 compared to conventional starters?
A: Energy savings typically range from 20-40% depending on application load profile, duty cycle, and process optimization. Variable-torque loads (fans, pumps) show highest savings. Detailed energy analysis available upon request with application data.

Q: What are the installation environment requirements and protection class?
A: Standard modules are IP20 rated for installation in enclosed control cabinets. Ambient temperature 0-40°C, altitude up to 1000m without derating. Avoid corrosive atmospheres, excessive vibration, and conductive dust. Adequate ventilation required for thermal management.
