Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Siemens 6SL3130-1TE31-0AA0 is a SINAMICS S120 Booksize Basic Line Module engineered to serve as a central power supply unit for multi-axis industrial drive configurations. Operating on a three-phase input supply range of 380 V AC to 480 V AC with a rated input current of 188 A, this uncontrolled non-regenerative infeed module converts AC line power into a continuous 600 V DC link supply. Delivering a rated power output of 100 kW and a continuous output current of 208 A, the air-cooled unit utilizes a diode and thyristor bridge design with internal precharging circuitry. Operating heat loss is maintained at 420 W, optimizing cabinet space and thermal management in high-density drive enclosures.
System connectivity relies on an integrated DRIVE-CLiQ interface with a single RJ45 socket operating at 100 Mbit/s, connecting directly to a central Siemens SINAMICS CU320-2 Control Unit. An internal electronic rating plate automatically transfers module identification and operating parameters over DRIVE-CLiQ, eliminating manual data entry during commissioning. Commissioning, configuration, and diagnostics are managed using engineering tools such as STARTER or SINAMICS Startdrive in TIA Portal, or via attached BOP20 and AOP30 operator panels. Integration into a drive lineup requires connecting the 3-phase line AC input, external 24 V DC control power at terminal X24, line reactors, and side-by-side DC busbars shared with adjacent Booksize Motor Modules. When configuring a spare unit, ABC Industrial Parts can assist maintenance teams with tested replacement modules and technical support for rapid setup.
Visual status monitoring is located on the front panel via multi-color RDY (Ready) and DC LINK LEDs. The RDY LED indicates readiness (green), precharging status (yellow), active faults (red), or firmware download status (flashing green/red). The DC LINK LED displays orange when DC link busbar voltage exceeds safe touch thresholds at 60 V DC or above, turning off below 60 V DC and showing red during overvoltage conditions. Diagnostic mechanisms record active fault codes in the Control Unit buffer, providing clear failure indicators such as precharge path faults (F06000), line supply failures (F06100), power unit overcurrent (F30001), and heat sink overtemperature (F30004). Board-level hardware errors, such as internal component or memory corruption (F30050), are not field-serviceable; in such instances, ABC Industrial Parts offers repair services and replacement units to minimize machine downtime.

Programming and Configuration
Parameterization and commissioning of the 6SL3130-1TE31-0AA0 are performed through standard Siemens software environments, specifically the STARTER commissioning tool and SINAMICS Startdrive integrated within TIA Portal. These software suites communicate with the line module indirectly via the connected SINAMICS CU320-2 Control Unit.
The module features an integrated electronic rating plate stored in non-volatile internal memory. Upon establishing physical connectivity via the DRIVE-CLiQ interface, the CU320-2 Control Unit automatically reads the rating plate data, configuring the drive topology, voltage constraints, and power limits without requiring manual hardware parameter definition.
Direct control cabinet diagnostics and configuration monitoring can also be executed without a laptop using attached BOP20 (Basic Operator Panel) or AOP30 (Advanced Operator Panel) units mounted directly to the host Control Unit.
Communication and System Integration
System communication is established via a built-in DRIVE-CLiQ interface featuring a single RJ45 socket rated for 100 Mbit/s transfer speeds. DRIVE-CLiQ carries digital diagnostic signals, operational telemetry, and electronic rating plate identification between the module and the CU320-2 Control Unit.
In cabinet layouts, the module integrates into multi-axis systems using the modular Booksize format. It connects physically to adjoining Motor Modules via shared top-mounted DC link busbars supplying 600 V DC and internal 24 V DC auxiliary power terminals.
Diagnostics and Status Indication
Operational state diagnostics are communicated via front-panel LED indicators and internal registers. The RDY LED displays module readiness, precharging activity, active faults, and firmware updates, while the DC LINK LED provides visual indication of the DC busbar voltage state relative to safety levels.
Detailed fault logs and alarm history are continuously monitored and logged by the central Control Unit. Maintenance personnel can interrogate the diagnostic buffer through STARTER, Startdrive in TIA Portal, or connected BOP20/AOP30 panels to investigate line voltage instability, ground faults, or overtemperature events.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| RDY (READY) | Green/Yellow/Red - Solid / Flashing | Green: Ready for operation. Yellow: Precharging active or line voltage present. Red: Fault present (e.g. overtemperature, precharge fault, hardware fault). Flashing Green/Red: Firmware downloading. |
| DC LINK | Orange/Red - Solid / Off | Off: DC link voltage < 60 V DC. Orange: DC link voltage >= 60 V DC. Red: DC link overvoltage or fault condition. |
Replacement and Spare Part Considerations
Before replacing a 6SL3130-1TE31-0AA0 line module, ensure incoming 3-phase line power and auxiliary 24 V DC supply are disconnected. Confirm that the DC LINK LED is completely unlit, verifying that the DC link busbars have discharged below 60 V DC.
Because Basic Line Modules are non-regenerative and cannot send power back to the grid, applications subject to motor braking deceleration must be equipped with external braking modules and resistors attached to the DC link to avoid overvoltage faults (F30002). Ensure that matching line reactors are correctly installed in line with the AC input to prevent internal precharging path failures (F06000).
When mounting a spare module, ensure all DC link busbar fastening screws, 24 V DC connections at terminal X24, and DRIVE-CLiQ communications cables are firmly secured. Once connected, the Control Unit automatically reads the unit's electronic rating plate upon power-up.
Error Codes & Fault Codes
The following error codes may be displayed during operation or diagnostics:
| Code | Name | Description | Possible Cause | Recommended Action |
|---|---|---|---|---|
