HZF combining filters are an integral part of the Rexroth Indramat servo drive systems and are exclusively provided for operation with specified power supply modules. The function of the combining filter is to suppress the current leakages from parasitic capacities such as motor cable and winding capacities, ensure sufficient interference suppression, and stable power supply to the Rexroth Indramat drive system.

HZF combining filters are applicable with HVR power supply units consisting of a clocked 3-phase IGBT jumper and a KDxx commutation choke. When combining filter malfunctions or breaks down, some of the issues that can arise include:

• Unstable and unreliable power supply to the servo drive.
• Noise emission from servo drive and non-compliance with electromagnetic compatibility (EMC) standards.
• Inaccurate motor control and electrical noise interference with the sensitive circuitry of the servo drive.
• Data transmission and system synchronization issues, especially for Rexroth Indramat servo drives that are reliant on CANopen, Profibus, or SERCOS communication protocols.
• Overall, a faulty combining filter undermines the reliability of the servo drive system.

As soon as your drive system begins to encounter these issues, you need to reach out to professionals for immediate assistance. For most people, they don’t know who to call or what to do– if you’re in that group, you’re in luck! Wake Industrial has got you covered.

We are a trusted expert in Rexroth Indramat HZF servo drive repair. With deep knowledge and experience, our skilled technicians swiftly diagnose and resolve issues, ensuring minimal downtime and optimized productivity. The repair process begins with an initial assessment (visual inspection). The next phases include diagnostic testing, disassembling, and component inspection, continuity and resistance testing, filter element replacement, reassembly and testing, verification & calibration. Finally, the repaired combining filter is reintegrated into the drive system and tested under varying standard load conditions to ensure stability, reliable power supply, and proper communication.

At Wake Industrial, we understand the importance of customer satisfaction and we strive to get things done right the first time. With our reliable and efficient Rexroth Indramat HZF servo drive repair services, you can trust us to deliver exceptional results. Contact us TODAY!
