Product Description:
The RZM01.1-5-290 is a passive line component built by Bosch Rexroth Indramat for the RZM Motor Filters series. As a motor filter, it is installed between the drive and the servomotor to damp voltage spikes, reduce common-mode noise, and limit cable-borne electromagnetic interference in industrial automation systems that run long motor leads. This device helps preserve insulation life and keeps conducted emissions within drive limits during high-frequency pulse-width-modulated operation. It is particularly useful where the cable run between the cabinet and the motor can increase reflected-wave stress at the winding terminals.
The filter accepts a three-phase supply of 3 × AC 500 V ±10 %, so it ties directly to standard 480 V class inverters without separate step-down hardware. Its Design 1 coding shows that it uses the first mechanical layout in the series, while Line 1 denotes the primary electrical configuration for this family. A long cable connected to the drive can transmit switching harmonics, and the unit limits those components to a maximum fundamental of 100 Hz when the motor leads exceed the manufacturer's long-cable criterion. When a shielded cable is present, attenuation increases because the shield works in combination with the internal inductance; a 50 % shielded-line factor indicates that the filter halves the reflected overvoltage under typical conditions.
When the motor leads are short, the allowable carrier spectrum doubles and the cutoff rises to 200 Hz, permitting faster switching patterns without violating filter impedance limits. Classified simply as a Motor Filter, the device maintains a compact footprint for mounting near the drive cabinet. Its placement on the output side of the drive lets the inverter continue normal switching while the filter smooths the waveform seen by the motor cable. In applications that require very quiet torque production, such as packaging actuators or pick-and-place axes, the model helps meet emission goals while staying within the intended thermal range.
