178F7562 by Danfoss

The 178F7562 is a low-voltage AC drive produced by Danfoss within the VLT 2800 Low Voltage Drives series. It regulates the speed and torque of induction motors in automated process equipment by varying output frequency. This allows the control system to match motor performance to changing load demands, which can reduce wasted energy and mechanical stress on connected equipment. It is commonly used on pumps, fans, and conveyors where operating speed must change with demand rather than remain fixed at line frequency. Its compact design suits cabinet or machine-mounted installations where available space is limited.

Rated at 20 HP, the unit provides a continuous mechanical output of 15.0 kW. It accepts a supply of 380-480 V ± 10% 50/60 Hz on a three-phase line, which matches common industrial power systems. The enclosure carries an IP20 rating, so it is finger-safe but should be installed inside a clean cabinet for protection from dust and moisture. A standard brake chopper handles regenerated energy during rapid deceleration, which is useful in applications with frequent stopping. The drive is supplied without an application option card or fieldbus interface, so control is handled through its basic terminals and analog signals.

The slim Bookstyle enclosure helps reduce panel width, and the exterior uses a coating finish to resist airborne contaminants found in process environments. A built-in display (SLCP) provides local access to parameters and fault codes without requiring a separate keypad. The local interface also makes status information available directly at the drive during startup and normal operation. Electromagnetic compliance is supported by a cable-length-dependent (A1 or B) RFI filter selection, which lets the installation be matched to the motor cable run. The drive is intended for process applications and includes PID-based control functions for closed-loop regulation of variables such as pressure, flow, or level.
