Product Description:

The 176F7002 is a variable-frequency drive manufactured by Danfoss for the VLT 6000 HVAC Drives series. It converts fixed-frequency mains power into a modulated output that allows building automation controllers to adjust the speed of induction motors. This speed control helps air-handling units, pumps, and cooling towers match their output to changes in airflow or water-flow demand. Regulating motor speed can reduce the need for mechanical throttling through dampers or valves, which may lower energy consumption and limit wear in commercial and industrial ventilation systems.

The drive accepts a line supply of 200–240 VAC, making it suitable for common three-phase, low-voltage power networks. Its output is rated at 30 kW (40 HP) for connected HVAC motors operating within the permitted load range. The Compact IP00 enclosure does not provide protection against contact, dust, or moisture, so the drive must be installed inside a suitable secondary cabinet. Setpoints and operating parameters are accessible through the included LCP (Local Control Panel), which also provides local access to status information and fault codes. The unit is supplied without an RFI filter, so an external filter may be required when the installation must meet limits for conducted electromagnetic interference.

The hardware is supplied as a standard unit without specialized thermal, harmonic, or safety expansions. Its uncoated control electronics are not protected against corrosive gases or condensing humidity, so the cabinet should provide a clean and dry operating environment. The drive has no fieldbus option, which means remote speed references and control commands must use the available hardwired control inputs rather than an optional network interface. Local commands can also be entered through the control panel when direct operation is appropriate. The configured application is Graham, while the drive retains its standard HVAC control functions for regulating fans, pumps, and related motor-driven equipment.
