Product Description:
The RZM01.1-5-630 output filter module is produced by Bosch Rexroth Indramat within the RZM Motor Filters series. Positioned between a pulse-width-modulated drive and its servo motor, the unit attenuates steep voltage edges that can overheat windings or stress insulation. By matching the impedance of shielded motor leads and limiting reflected-wave effects, it supports stable drive operation in automated machinery and packaging lines where cable distances and fast switching frequencies would otherwise raise overvoltage risks. By smoothing the inverter output before it reaches the motor terminals, the module helps reduce electrical stress along the cable run and at the motor connection points.
Its input terminals accept a nominal line of 3 x AC 500 V ±10 %, so the filter can be mounted on common 480 V industrial buses without additional transformers. The circuitry is optimized for inverter switching frequencies within a range of 4 to 8 kHz; inside this band, the differential inductance and damping resistors shape the current so that motor voltage spectra remain within the expected operating range. When the pulse rate is 4 kHz, the filter restricts motor-side fundamental frequency to 100 Hz, which helps curb dielectric stress on the winding system. At the higher 8 kHz carrier, the permissible fundamental rises to 200 Hz, and total cable length may extend to 120 m while the output waveform remains controlled.
A shield coverage factor of 50% is incorporated into the design equations, and using cables that meet or exceed this braid density further reduces common-mode currents at the motor housing. The product is categorized as Design 1 in the configuration matrix and is assigned to Line 1, indicating a consistent mechanical layout and mounting pattern within similarly coded components. Within that structure, the part is officially classified as a Motor Filter. This arrangement suits installations where long motor leads and high-frequency drive operation would otherwise increase voltage stress at the motor terminals.
