Application-Specific FAQ
Q: Can the 6SL3120-11E23-0AA3 be used with a SINUMERIK 840D sl CNC?
A: Yes. When paired with a CU320-2 PN Control Unit and configured via STARTER or TIA Portal, this module integrates seamlessly with SINUMERIK 840D sl for multi-axis CNC applications.
Q: What is the maximum motor power this module can drive?
A: At 3 A continuous output and 600 V DC link, the module is suited for servo motors up to approximately 1.1–1.5 kW depending on motor efficiency and duty cycle.
Q: Is STO (Safe Torque Off) supported without an external safety relay?
A: Yes. The 6SL3120-11E23-0AA3 has integrated STO terminals, enabling SIL 2 / PLd safety without additional external relays when wired per Siemens safety guidelines.
Q: Can multiple Single Motor Modules share one Line Module?
A: Yes. SINAMICS S120 booksize architecture uses a shared DC bus, allowing multiple Motor Modules to be powered from a single Line Module, with energy regeneration between axes.
Q: Do you provide firmware and parameter backup files?
A: We can provide available documentation. For project-specific commissioning support, contact our technical team.
