176F7002 by Danfoss

The 176F7002 is an HVAC drive produced by Danfoss for the VLT 6000 HVAC Drives series. It functions as a variable-frequency controller that adjusts the speed of ventilation and pumping equipment in automated building systems, allowing energy-efficient modulation of airflow and liquid circulation instead of fixed-speed operation with mechanical throttling. By integrating into standard control cabinets, the drive supplies the precise motor regulation required by building management systems that coordinate temperature, pressure, and air quality targets.

This model accepts a single-range input of 200-240 VAC, so it pairs with low-voltage three-phase power commonly used in commercial facilities. Its power section supports a continuous rating of 30/40 kW/HP, covering medium-size supply and return fans or multi-pump skids. The housing uses the space-saving Compact IP 00 style, meaning it has no formed enclosure and must be installed inside a suitable panel for protection from dust and accidental contact. A front-mounted graphical interface with an LCP allows parameter changes and process feedback without extra handheld tools. Internally, this is a standard unit, so the control terminals, relay outputs, and analog inputs follow the baseline VLT 6000 pinout without factory-installed extensions.

For installations where conducted emissions are handled elsewhere, the drive is supplied without a filter, leaving space and thermal headroom for an external EMI component if needed. The power board has no coating, which suits clean mechanical rooms but requires use away from high-humidity or corrosive areas. The target application is listed as Graham, indicating a predefined parameter set for that manufacturer's air-handling equipment. Communication add-ons are streamlined because the fieldbus slot has no options installed, so speed references must arrive through the analog inputs or onboard digital contacts, while the application-option bay remains available for future upgrades such as fire-mode or cascade-control cards.
