Product Description:

The RZS01.1-6-195 sinusoidal filter is manufactured by Bosch Rexroth Indramat and is part of the RZS Sinusoidal Filters series. Installed on the output side of a drive inverter, the filter smooths high-frequency switching edges so the connected motor receives a cleaner sinusoidal voltage. By limiting voltage overshoot and common-mode noise, it helps protect winding insulation and reduces conducted emissions in automation cabinets where multiple drives share the same mains supply. This type of filter is especially useful when motor cables are long or when pulse edges from PWM switching would otherwise place extra stress on the motor and adjacent wiring.

The filter is designed for three-phase systems operating at 3 x AC 380 ... 400 V, and it accepts a line deviation of ±15 % so the device remains functional when plant voltage drifts from nominal. Its current path is rated for a continuous 195 A, which suits medium-power inverters used with induction or synchronous motors in steady industrial duty. Internal copper windings and laminated cores dissipate 600 W of power loss, so enclosure ventilation must remove that heat during sustained operation. The drive should use a carrier frequency of 8 kHz, and the filter passes the motor-side fundamental over 0 ... 200 Hz without materially attenuating the commanded waveform. That operating range supports both low-speed motor operation and higher-speed running above base frequency.

The unit matches converter power classes 110 / 132, indicating compatibility with inverters in the 110 kW and 132 kW range. It belongs to Product Line 01. The mechanical layout uses Design Version 1, which keeps mounting dimensions and terminal spacing consistent for this model. Because the filter sits between the inverter and motor, matching the power class and layout helps keep conductor routing and panel placement appropriate for the connected drive.
