178B2130 by Danfoss

The 178B2130 is a decentralized AC drive from Danfoss and is part of the FCD 300 Micro Drives series. Mounted directly on machinery, this drive eliminates long motor cables and delivers localized speed control for conveyors, mixers, and other processing equipment. By integrating power electronics, control logic, and sealing into one enclosure, it simplifies plant layouts and supports installation in production zones that benefit from on-machine variable-frequency control.

The unit accepts a three-phase supply of 3×380-480 V, matching common low-voltage grids found in industrial facilities. Its inverter section is sized for a continuous mechanical output of 0.75 kW, while the motor shaft can deliver up to 1.0 HP for light-to-medium loads. Protection against dust ingress and high-pressure water jets is verified by the IP66 rating, so the drive can be mounted outside a panel without auxiliary covers. An extended 24 V option is included, allowing the control board to remain powered by an external supply for supervision or parameter access during main power shutdowns. Terminals are presented in a wall-mount box with metric threads, enabling rigid conduit or gland fittings to be attached directly at the point of use.

Noise compliance is aided by an integral 1 A RFI filter that suppresses conducted emissions on the mains lines. Communication tasks are simplified because the design is supplied without a fieldbus interface, making it well suited for stand-alone loops where analog or hard-wired control is sufficient. Parameter access is possible through a display connector that supports the detachable keypad used across the series. The drive is intended for processing applications and has a standard coating that withstands routine washdown and cleaning agents encountered in food or chemical production areas.
