Product Short Description
Product Name
HZF01.1-W045N combining filter/mains interference filter for Indramat DIAX04, AF drive, and HVR/HMV power-supply systems, also quoted as HZF011-W045N.
Product Introduction
The HZF combining filter suppresses radio-frequency and mains-borne interference at the drive supply input. It combines mains filtering and DC-bus filtering functions for Indramat servo power systems. The W045 designation defines the 45 kW power class; the module is installed together with the supply unit to reduce EMI and stabilize commutation performance.

Functional Features
RFI/EMI attenuation on the supply side.
Combined mains and DC-bus filtering for HVR/HMV supply modules.
Leakage-current and commutation-noise reduction.
Maintenance-free passive cooling.
Application Scenarios
Indramat DIAX04 servo drives.
AF-series regenerative and non-regenerative drive systems.
HVR/HMV cabinet power supplies in machine tools, printing presses, and material-handling systems.
Retrofit of 400/480 VAC industrial servo cabinets requiring mains EMI compliance.
Performance Parameters
Rated load power up to 45 kW in the defined drive configuration.
Sustained current up to 80 A in the specified combining-filter version.
Passive loss values and thermal rise depend on load current, cabinet ventilation, and supply harmonics.
Materials And Construction
Steel filter enclosure with painted/coated finish.
Copper mains terminals and DC-bus connections.
Internal reactors, capacitors, and RFI filtering elements.
Panel-mounting frame and grounded cabinet bracket.
Working Principle
The filter receives three-phase mains and the associated DC-bus connections from the supply module. Inductive and capacitive network elements attenuate high-frequency noise, limit dv/dt, and reduce conducted emissions. The combined circuit improves current quality on the mains side and supports stable DC-bus operation for the inverter stage.
Installation Requirements
Mount directly beside the HVR/HMV supply unit as specified by the Rexroth layout.
Use shielded or approved mains cabling between filter and supply.
Connect DC-bus terminals with correct polarity and torque values.
Provide adequate cabinet clearance for natural convection.
Bond the enclosure to the cabinet protective-earth system.
Usage Precautions
Only qualified drive personnel perform installation.
Verify supply voltage, frequency, and current rating before energizing.
Do not operate without the associated supply module or with open DC-bus covers.
Observe ambient temperature limits, typically -5°C to 55°C for the HZF01.1-W045N version.
Inspect terminals regularly for tightness and insulation damage.
