Internal Product Review
RZS01.1-6-135 is a Bosch Rexroth Indramat sinusoidal filter designed for 3 x AC 380 to 400 V drive systems. A 135 A nominal current rating and 0 to 200 Hz operating range give the unit solid capability in high-demand motion applications. The 8 kHz pulse frequency is a particularly strong specification for maintaining smooth filter performance.

Product Description:
The RZS01.1-6-135 is a sinusoidal filter manufactured by Bosch Rexroth Indramat for the RZS Sinusoidal Filters series. Installed between a pulse-width-modulated drive inverter and the motor, this passive component smooths the steep voltage edges generated by the inverter so that the motor windings receive a near-sinusoidal waveform. By lowering dv/dt stress and audible noise, the filter supports longer motor cable runs and reduces insulation wear in industrial automation systems that rely on variable-frequency operation.
The filter is designed for a line connection of 3 x AC 380 … 400 V, and the input can deviate within a tolerance of ±15 % without derating. It carries a nominal output current of 135 A, matching medium-power converters that feed multiple induction or synchronous machines. Internally tuned inductance and capacitance networks are optimized for a carrier or pulse frequency of 8 kHz; this value aligns with the switching pattern of most Rexroth drive controllers to minimize common-mode currents. The RZS topology maintains a working bandwidth from 0 … 200 Hz, allowing the connected drive to vary motor speed from standstill up to four times the base electrical frequency while keeping the output waveform within harmonic limits dictated by EN 61800-3. The unit belongs to product line 01 and is cataloged under design version 1, which fixes dimensional and connector positions for cabinet mounting.
The maximum output frequency the filter can pass without core saturation reaches 200 Hz, so torque delivery at elevated speeds is not limited by the magnetic circuit. Thermal dissipation under rated conditions is held to 400 W; this figure guides enclosure ventilation sizing to keep the winding temperature below the insulation class limit. Compatibility with converter power class 090 ensures impedance matching with drive modules that supply up to 90 kW of shaft power. Design version 1 also confirms that this model shares mechanical footprints with other first-generation RZS units, easing retrofit or parallel installation inside standardized 600-mm switchgear frames.
