Product Description:

The 178F7562 is an AC variable-frequency drive produced by Danfoss for the VLT 2800 Low Voltage Drives series. Designed for panel mounting in industrial automation, the unit converts fixed mains power into a variable output that controls induction motor speed in process equipment. By modulating frequency and voltage, it allows motor torque to match real-time load demands, reducing energy consumption and mechanical wear across conveyors, pumps, and general process machinery. Its compact design supports installation in control cabinets where available mounting space is limited.

Electrically, the drive tolerates a mains range of 380–480 V ±10% at 50/60 Hz, so it can operate with common industrial power supplies. It is designed for a three-phase power network, allowing symmetrical current draw and reducing ripple on the DC link. Output capability reaches 20 HP, while the nominal electrical power is 15.0 kW; these values support appropriate motor selection and thermal planning. The front panel has a built-in display that presents setpoint values, feedback, and alarm codes without requiring an additional display module. An enclosure rating of IP20 provides protection against accidental finger contact but requires installation inside a suitable cabinet when dust or moisture is present. The drive does not include an application option or fieldbus card, which keeps the internal architecture simple and reduces the space required for installation.

Mechanical integration is aided by the book-style format, allowing multiple units to be mounted in narrow motor control center columns while sharing cabinet airflow. The control board has a protective coating that resists humidity and airborne chemicals commonly found in process plants. Electromagnetic compatibility is supported by an integrated RFI filter with a cable-length-dependent Class A1 or B rating, allowing the appropriate attenuation class to be selected according to the motor cable length. Torque limiting during rapid deceleration is handled by the braking transistor included in the standard configuration with a brake. The drive uses a process-oriented application profile suited to pumps, conveyors, and other equipment that requires adjustable motor speed. It is supplied without supplementary application software, leaving control functions available through the drive’s standard parameter structure.
