Specifications:
The Siemens Simodrive 611 Infeed Module (
6SN1145-1AA01-0AA1 /
0AA2) is an unregulated 10/25 kW line infeed/energy recovery-capable supply unit designed for 400V–480V AC inputs. It pairs directly with the
Simodrive PW-Modul INT/EXT (
6SN1113-1AB01-0BA1), a matching pulsed resistor (bleeder) module used to dissipate excess regenerative braking energy.
Simodrive U/E Module (10/25 kW) Specs
- Part Numbers:
6SN1145-1AA01-0AA1, 6SN1145-1AA01-0AA2
- Module Type: U/E (Uncontrolled Infeed / Regenerative Feedback – U/E = Ungeregelt / Rückspeisefähig)
- Continuous Power Rating: 10 kW
- Peak / Intermittent Power Rating: 25 kW
- Input Line Voltage: 400V to 480V AC (3-phase, ± 10%), 50/60 Hz
- DC Link Output Voltage: Approx. 600V–700V DC (depending on line input and switch settings)
- Cooling Options: Internal / External heatsink configuration (INT/EXT)
- Features: Integrated electronic mains contactor control, break contact monitoring, and fault reporting outputs
Simodrive PW-Modul (INT/EXT) Specs
- Part Number:
6SN1113-1AB01-0BA1 (often spanning Version C or D builds)
- Module Type: PW-Modul / Pulsed Resistor Module (Pulswiedergabe / Braking Resistor Unit)
- Functionality: Provides dynamic DC-link voltage clipping and heat dissipation during rapid axis/spindle deceleration cycles
- Compatibility: Universal housing, designed to mount directly next to the 10/25 kW infeed block
- Monitoring: Features internal thermal and switch-on time monitoring to prevent resistor overload
- Cooling: Supports internal or external cabinet airflow layout matching the main drive line
If you are troubleshooting an error code or planning a replacement, please let me know:
- The exact alarm or fault code showing on your drive (such as an overvoltage or DC-link fault)
- The specific machine/controller setup (e.g., Sinumerik 810D/840D)
I can help you pinpoint configuration settings or check compatibility
