Siemens 6SL3120-1TE26-0AC0

The 6SL3120-1TE26-0AC0 motor module from Siemens’ SINAMICS S120 series is an efficient and dependable power converter with a wide range of industrial uses. In challenging conditions, high levels of integration and flexibility are required, and this module, thanks to its sturdy build and sophisticated safety features, is well-suited for such settings.

Technical Specifications:

The Siemens 6SL3120-1TE26-0AC0 operates at a 3-phase 380 V to 480 V AC ±10 line voltage. It has a frame measurement of FX and measures 326 mm in width, 1400 mm in height, and 356 mm in depth, weighing 104 kg. The motor module is rated for IP20 or IPXXB protection.

It can accept a rated current of 229 A, a base load current of 205 A, and a base load current (IH) of 178 A. The maximum current (Imax) is 307 A. The rated pulse frequency is 2 kHz without derating and 8 kHz with derating.

The module generates 3-phase AC 400V at 60A from DC 600V. A Booksize C-Type frame and internal air cooling are included. The cooling air needed is 0.17 m³/s, and the power loss is 2.46 kW. Temperatures range from 0°C to 40°C without derating and up to 55°C with derating. It can work from -10°C to 40°C and store from -25°C to 70°C. The non-condensing humidity tolerance is 5%–95%. Siemens 6SL3120-1TE26-0AC0 uses PWM control and provides 150% starting torque.

EtherNet/IP, PROFIBUS, and PROFINET control interfaces complement six programmable digital inputs and two outputs. Two analog inputs and outputs (0-10 V, 0-20 mA) are included. This terminal has DRIVE-CLiQ for easy connecting and diagnostics and an RS485 serial interface for parameterization and diagnostics.

The module meets the criteria of SIL2, PLd Cat.3 (Safety Integrated Functions). Protection features include overvoltage, undervoltage, overcurrent, and ground fault. It can handle 0.8 A at 24 VDC and 229 A input current.

The electronics power supply operates at 24 VDC (20.4-28.8 VDC). The undervoltage trip is set at 424 VDC, while the overvoltage trip at 820 VDC ± 2%. The type rating is 110 kW for In and 90 kW for IH.

Connection Specifications:

The M10 cable lug provides line supply connections (U1, V1, W1) using a planar connector with a maximum cross-section of 2 x 185 mm². Motor connections (U2, V2, W2) utilize a flat connector with an M10 cable receptacle, enabling a maximum cross-section of 2 x 240 mm². DCPA and DCNA employ flat connectors for M6 cable lugs (1 x 35 mm²), while DCPS and DCNS use M8 cable lugs (1 x 70 mm²) for DC link connections (brake module, dV/dt filter).

Fuse Specifications:

The Siemens 6SL3120-1TE26-0AC0 requires NH fuses with a rated current of 3NA3144 (250 A) and UL Class J fuses with an SCCR of 65 kA. UL489 / CSA C22.2 No. 5-02 requires 3VL3125-3KN30-0AA0 (250 A) with a short-circuit current rating of 65 kA, while IEC 60947 requires 200 to 250 A.
