6SL3202-0AE26-2SA0 SIEMENS Exclusive Sinus Filter Original Brand New

The 6SL3202-0AE26-2SA0 SIEMENS sinus filter is an advanced component engineered for reliable operation within SINAMICS drive systems. Developed to create smooth motor voltage characteristics, this filter helps ensure long-term equipment protection and stable industrial performance. By minimizing high-frequency voltage spikes and moderating dv/dt behavior on the motor terminals, the unit supports a controlled electrical environment that contributes to extended motor insulation life. Its ability to deliver cleaner output waveforms allows the connected equipment to function more quietly and efficiently across a range of load conditions.

This sinus filter enables the use of longer motor cable runs without exceeding insulation limits, offering flexibility when drives and motors must be positioned apart. The reduction of bearing currents further supports compatibility with standard motor designs that lack special insulated components. Because the voltage applied to the motor is nearly identical to a line-fed system, thermal stress and winding load remain balanced, helping reduce premature wear while promoting consistent performance. These characteristics make the 6SL3202-0AE26-2SA0 suitable for a wide variety of industrial applications that require dependable drive-to-motor connectivity.

The filter’s influence on electromagnetic compatibility (EMC) is another valuable aspect. With lower voltage gradients along the motor cable, electromagnetic emissions are reduced, which can simplify installation when shielded cables are not preferred or required for short cable lengths. Users also benefit from reduced motor acoustic noise, as the smooth voltage waveform eliminates pulsed excitation that normally generates additional audible disturbances. This contributes to a more comfortable working environment and decreases operational noise levels.

When applying the sinus filter, several operational factors must be observed. Appropriate pulse frequencies between 4 kHz and 8 kHz should be maintained for outputs up to 90 kW, and the output frequency must remain at or below 150 Hz. Commissioning should only be performed with the motor connected, as the filter is not designed for no-load operation. Automatic pulse-frequency reduction features must also be disabled during use to preserve system stability.

Overview

Sine-wave filters are designed to shape the converter output into a nearly sinusoidal waveform. Their purpose is to reduce voltage peaks, support longer cable routing, and protect motor insulation systems. By working similarly to output reactors but with higher efficiency, these filters deliver improved electrical quality and quieter machine operation. They also contribute to reduced electromagnetic interference, enhancing overall system compatibility.
