Product Description:
The 178B0797 frequency converter is manufactured by Danfoss for the VLT 6000 HVAC Drives series. As an adjustable-speed drive, it regulates the output of induction motors used in ventilation systems, chilled-water pumps, and air-handling equipment. Matching motor speed to the actual load can reduce unnecessary energy consumption while helping building automation systems maintain stable indoor conditions. The converter is suitable for installation in mechanical rooms, equipment areas, and integrated control panels serving commercial HVAC systems.
The converter supplies up to 45 kW / 60 HP of continuous power and accepts a three-phase mains supply of 380–460 VAC, making it compatible with common 400 V distribution systems. Its compact IP54 enclosure protects internal components against dust and splashing water, allowing wall mounting near a connected fan or pump when installation requirements are satisfied. Conducted emissions are reduced by an integrated Class A1 and Class B filter, which supports compliance with applicable electromagnetic compatibility limits without requiring separate filtering components. Communication with building management controllers is provided through Profibus DP V1, allowing parameter values, operating commands, and process feedback to pass over the fieldbus at configurable communication rates. A detachable LCP (Local Control Panel) provides local access to setpoints, operating status, alarms, and stored drive parameters. The keypad also allows operating values to be reviewed directly at the converter without requiring continuous access through the building management network.
The control software is configured for HVAC duty and includes predefined functions for applications such as supply fans and return fans. The unit is supplied with no optional application accessories, while the base package includes the auxiliary input and output functions needed for its intended control tasks. Its uncoated power boards are suitable for locations where condensation, corrosive vapors, and excessive humidity are controlled. The installation area should remain clean and dry enough to prevent contamination from accumulating on exposed electronic surfaces. Adequate clearance around the enclosure should be maintained so heat can dissipate during continuous operation, and cable routing should separate control wiring from motor and mains conductors to reduce electrical interference.
