Product Description:

The 175Z0546 is an AC frequency converter manufactured by Danfoss as part of the VLT 5000 Frequency Converters series. In automated facilities, this product modulates the voltage and frequency supplied to three-phase induction motors so that conveyor lines, pumps, or fan systems can maintain precise speeds under varying loads. The converter fits the modular VLT 5000 platform, allowing users to select the power rating, control electronics, and communication options that match the host machine architecture.

It is built in a book-style IP20 housing, a slim enclosure that fits into control cabinets while providing protection against accidental finger contact with internal components. The input section accepts a 380–500 V three-phase supply, and the power stage delivers 2.2 kW when the application requires 110% torque. A lower continuous rating of 1.5 kW applies at 160% torque for high-overload cycles. Regenerative energy is managed through an integrated brake chopper, identified as standard equipment with a brake chopper. For electromagnetic compatibility, the factory-installed filter provides Class A1 and Class B filtering, supporting operation on industrial power systems without excessive conducted electrical noise.

Control and communication features are centered on a process control card that handles analog references, digital input and output signals, and closed-loop adjustments. Networked installations can connect the converter to PLCs over Profibus DP V0/V1 at 12 Mbaud, providing parameter access and real-time status through a single shielded cable. The drive has no built-in option, so the application slot remains available for later additions such as sensor modules or support for other communication protocols. The unit uses non-coated circuit boards, which require installation in a clean, dry enclosure to reduce exposure to moisture and airborne contaminants. A front-mounted display provides local access for parameter entry, operating-status review, and fault diagnostics.
