Siemens 6SL3352-6TE35-0AA3 SINAMICS S120 Line Module

Siemens · SINAMICS S120 · Active / Smart Line Module · In stock

The 6SL3352-6TE35-0AA3 is a Siemens SINAMICS S120 chassis-format line module from the 6SL3352 family, used as the line-side rectifier that feeds the common DC bus of a multi-axis S120 drive system. It belongs to the same SINAMICS S120 / S150 / G150 power-module family we keep alongside Allen-Bradley PowerFlex, Mitsubishi MR-J, Yaskawa Sigma-7, and Schneider Altivar drive spares, so it fits a multi-brand cabinet where S120 drives share a backplane with PLCs from Omron, Panasonic FP, Fanuc, or KEYENCE vision systems.

The "6TE" position in the MLFB (Machine-Readable Product Designation) identifies an active / smart line-side converter block, while "35" indicates the current frame size. The exact kW rating and whether the unit is a Basic Line Module (BLM), Smart Line Module (SLM) or Active Line Module (ALM) should be confirmed from the nameplate on the front bezel before substitution. For multi-axis machines such as printing presses, packaging lines, paper machines, extruders, machine tools, cranes and large elevators, this module typically sits at the head of a SINAMICS S120 line-up as the regenerative or non-regenerative DC-bus supply. Sourcing from KOEED lets you keep one BOM supplier for the whole cabinet — send the full part list to Moritta@KOEED.COM and we will quote availability and price within 24 hours.

1. Key Technical Specifications

Note: power class (kW), ALM vs SLM firmware and connector layout must be cross-checked against the unit’s nameplate. Send a clear front-panel photo to Moritta@KOEED.COM and we will confirm the exact variant before shipping.

2. Application Scenarios — Where It Fits

A SINAMICS S120 line module is the single point of common-DC-bus conversion in a cabinet, so it shows up wherever a machine has several coordinated axes drawing from one shared DC link. Typical installations include:

• Printing and converting machines — multi-motor webs with dancer and tension control, often paired with a SINAMICS S120 Motor Module per axis
• Packaging lines — form-fill-seal, labelling, palletising and wrapper sections, typically integrated with an Allen-Bradley ControlLogix or Omron NJ/NX PLC for line coordination
• Paper machines and corrugators — sectional drives where regenerative energy from the unwinder must be returned to the line, which is exactly why an Active or Smart Line Module is preferred over a passive diode rectifier
• Plastics extruders and rubber calendering — screw + haul-off + winder, often controlled by Siemens SIMATIC S7-1500 or Mitsubishi iQ-R
• Machine tools — lathes, milling centres and grinders using SINUMERIK 840D sl with multiple S120 axes on a common DC bus
• Cranes, hoists and elevators — vertical-motion applications where regenerative braking energy from the lowering motion is fed back through the line module
• Test stands and laboratory drive rigs — any multi-motor dynamometer or e-machine test bed that benefits from a shared DC bus

Because KOEED also stocks Fanuc spindle amplifiers, Yaskawa Sigma-7 and Schneider Lexium servo spares, mixed-brand cabinets can be quoted in a single BOM — see the full brand index for what we cover side-by-side with Siemens.

3. Integration & Wiring Notes

Wiring a SINAMICS S120 line module is straightforward if the cabinet layout follows the Siemens SINAMICS S120 manual, but a few points are commonly missed on retrofits and on cross-brand cabinets:

• Line-side power wiring: 3-phase 380–480 V AC L1/L2/L3 to the input terminal block of the line module. The PE conductor must be bonded to the cabinet ground bar with the shortest possible pigtail; high-leakage line modules require a reinforced PE per the manual.
• DC bus link: the DC link bars (DC+ / DC−) on top of the module are the common bus to every downstream Motor Module. Verify bus-bar gauge and tightening torque when retrofitting older cabinets, especially when adding a third-party drive into the same DC link.
• DRIVE-CLiQ topology: connect the line module’s DRIVE-CLiQ port to the CU320-2 control unit (or a SINUMERIK NCU) with the supplied cable. The line module must be addressed first in the automatic topology, before any Motor Module.
• Braking / regeneration: for ALM variants, no external braking resistor is required; for SLM and BLM variants, a Brake Module + resistor may be required if the system cannot absorb regenerated energy. Confirm the topology on the nameplate before ordering.
• 24 V control power: SINAMICS S120 chassis modules require a separate 24 V DC supply for the control electronics; do not back-feed from the DC bus, and keep the 24 V return isolated from cabinet ground at a single point.
• EMC and line filter: for CE conformity, fit the recommended Siemens line filter upstream of the line module, and use shielded motor cables on every Motor Module downstream.
• Cross-brand PLC integration: if the line-up is commanded by an Allen-Bradley, Mitsubishi, Omron, Panasonic, Fanuc, Schneider or Yaskawa PLC, use PROFINET, EtherNet/IP, EtherCAT or Modbus TCP as required by the higher-level controller — the SINAMICS S120 control unit supports all four.

4. Installation & Commissioning Tips

• Mounting clearance: leave at least 100 mm above and below the module for airflow. The internal fan draws air bottom-to-top; blocking the inlet is the single most common cause of F30002 / F30003 overtemperature faults in the field.
• Torque and bus-bar preparation: clean the DC-bus mating surfaces with a non-abrasive pad and apply the contact aid specified by Siemens before joining the bus bars. Loose bus connections cause voltage spikes that can knock the line module into F30001 / F30007 on first power-up.
• First-time commissioning with STARTER / Startdrive: load the SINAMICS S120 firmware that matches the CU320-2 firmware, then run an "automatic configuration" so the line module is detected and addressed before the Motor Modules. A mis-ordered topology is the typical reason the line module is reported as "missing" in the project tree.
• Nameplate verification before power-on: compare the MLFB, hardware revision and rated current printed on the front bezel with the BOM. Mixing a 400 V line module into a 690 V cabinet is a destructive mistake — confirm the input class before energising.
• Spare-staging for legacy machines: older S120 chassis line modules are increasingly hard to source through authorised channels. KOEED keeps the 6SL3352 family and the wider 6SN11xx / 6SL3xxx SIMODRIVE / SINAMICS range in active stock for service engineers, and our AI Diagnostic Tool can identify the correct line module from a nameplate photo if the original paperwork is missing.
• Engineering notes for multi-axis retrofit: when replacing a faulted line module in a working cabinet, record the firmware version of the existing CU320-2 and the active topology XML before removing the old unit — importing the same topology into the new module avoids a full recommissioning cycle.
