Product Description:
The RZS01.1-6-068 is a sinusoidal filter produced by Bosch Rexroth Indramat for PWM drive systems in the RZS Sinusoidal Filters series. Positioned between a frequency converter and the motor, the component smooths the rectangular pulse train into a near-pure sine wave, which lowers dv/dt stress, acoustic noise, and electromagnetic interference in automated production cells. Its passive network of inductors and capacitors requires no control wiring, which simplifies installation inside standard control cabinets. This arrangement also helps protect motor windings during operation on converter-fed systems.
The filter connects to a three-phase supply rated at 3 x AC 380 to 400 V, matching common industrial line voltages. It carries a nominal line current of 68 A, so drives in that range do not experience noticeable voltage drop across the filter network. The inductive-capacitive network maintains a flat attenuation curve from 0 to 200 Hz, covering both constant-torque and higher-speed operating ranges of vector-controlled motors. When connected behind inverters that switch at 8 kHz, the filter limits differential-mode voltage slew to help protect motor insulation. During full-load operation, the component dissipates only 200 W, which simplifies cabinet ventilation and helps keep internal temperatures within allowable limits. The cleaner output waveform can also reduce audible switching noise at the motor.
Drive controllers in power classes 030 / 037 / 045 can be paired directly with this filter because its impedance and thermal ratings match their output stages. It is assigned to product line 01, and line deviations of ±15% are tolerated during operation. Hardware revision 1 uses the current winding geometry and capacitor set. No additional tuning is required when the unit is mounted close to the converter, and no separate control connection is needed for the filter itself.
