Product Description:

The RZS02.1-6-024 sinusoidal filter is produced by Bosch Rexroth Indramat and belongs to the RZS Sinusoidal Filters series. Installed between a pulse-width-modulated drive and an induction or synchronous motor, the filter smooths the square-wave voltage into a near-sinusoidal waveform. This reduces motor insulation stress and emitted interference in automated production cells. It also helps protect connected motor windings from steep voltage transitions at the motor terminals.

The RZS02.1-6-024 accepts an input of 3 x AC 380 ... 400 V, and the supply may deviate by up to ±15 % without functional loss, making the unit tolerant of common plant voltage swings. Under rated conditions, the filter carries a nominal current of 24 A, so it pairs with medium-power inverters while maintaining allowable temperature rise. Its inductive and capacitive network is tuned for a frequency range of 0 ... 200 Hz, which means the filter can pass the fundamental spectrum generated by standard vector drives while attenuating higher-order switching components. For applications that command elevated motor speeds, the design still transmits a fundamental frequency up to 200 Hz without excess voltage drop or phase shift, preserving torque capability across an extended speed range.

The switching pattern expected at the input has a carrier near 8 kHz, and the filter matches this pulse frequency so that differential-mode voltage peaks are minimized before reaching the motor terminals. At rated load, the internal components dissipate 140 W, which must be removed by cabinet airflow to keep temperatures within limit. Inverter models in power classes 015 / 018 are directly supported, giving a clear selection rule when planning. The unit is part of product line 02 and is delivered as design version 1, which keeps dimensions and connection layouts consistent with earlier RZS hardware.
