RZS02.1-6-080

RZS02.1-6-080, Bosch Rexroth Indramat, RZS Sinusoidal Filters deliver precision harmonic mitigation for demanding drive environments. This sinusoidal filter transforms rectangular PWM waveforms into smooth sinusoidal outputs with minimal residual ripple, ensuring motors operate with reduced insulation stress. With an LC filter topology, the RZS02.1-6-080 attenuates both differential and common mode noise, cutting electromagnetic interference on long unshielded cable runs. Its robust design safeguards motor winding insulation from overvoltage spikes and extends equipment lifespan through improved voltage quality.

The filter is specified for a Connecting Voltage of 3x AC 380 – 400 V ±15% (0 – 200 Hz) and a Max. Rated Current of 80 A with Connecting Voltage AC 500 V, supporting Line configuration 2 for two-stage attenuation. It delivers a selectable output frequency range of 0 – 200 Hz and maintains performance across variable drive speeds. Constructed with a film winding structure and Class F insulation, the unit withstands high electromagnetic forces and harsh ambient conditions. A current rating of 99 A affords headroom for transient loads, while the filter design can reduce effective motor cable length by 50% when shielded conductors are used. Input terminals U1, V1 and W1 facilitate straightforward installation with shielded cable connections to inverter outputs.

Engineered for seamless integration into Rexroth Indramat RD500 drive systems, the RZS02.1-6-080 mounts easily in control cabinets and requires no additional external components. Its low-pass filtering capability minimizes parasitic earth currents, enhancing system reliability and compliance with EMC directives. By smoothing drive output and suppressing voltage spikes, this filter maximizes motor uptime and reduces maintenance intervals, making it ideal for applications with long cable runs, high-precision positioning, or stringent noise-immunity requirements.
