Product Description:

The 178B8589 AC drive is manufactured by Danfoss and belongs to the VLT 2800 Low Voltage Drives series. As a variable-frequency inverter, it converts fixed mains power into a modulated output that allows motor speed, torque, and energy use to be regulated on process equipment such as small pumps, mixers, and conveyors in industrial plants. It fits inside electrical cabinets where panel depth is limited and supports the fundamental control functions needed for closed-loop or open-loop regulation without additional external modules.

The drive accepts a single-phase or three-phase supply of 200–240 V AC, so it can be wired directly to common low-voltage networks without an autotransformer. Its mechanically narrow book-style housing minimizes cabinet width and permits dense side-by-side mounting in multi-axis installations. A front-mounted built-in display (SLCP) provides local parameter entry and status readouts, eliminating the need for a remote keypad. The enclosure has an IP20 rating, which provides protection against accidental finger contact but not against liquids, so the unit must be installed inside a suitable cabinet. The power stage has a standard configuration with a brake, providing a dedicated brake chopper for dynamic motor stopping. The drive is supplied without an EMC filter, so external radio-frequency interference components may be needed when conducted-emissions limits apply.

Board-level protection against humidity and airborne contaminants is enhanced by a protective conformal coating, which can extend service life in areas near washdown processes even though the enclosure does not protect against liquids. Communication ports remain limited because the unit is supplied without a fieldbus option; speed references must therefore be delivered through analog signals or simple digital input and output connections. The drive is configured for process applications, with default parameter settings that support constant-torque loads and proportional-integral-derivative control used in flow or pressure loops. The compact housing conserves panel space, while the local controls provide direct access to operating parameters and drive status during routine use.
