Product Description:
The 178B5656 decentralized drive is produced by Danfoss within the FCD 300 Micro Drives series. Designed as a complete drive and motor-control unit that mounts directly on machinery, it eliminates long shielded motor cables and reduces cabinet space. Danfoss identifies the unit as product type FCD 300, and it is intended to adjust the speed of induction motors on conveyors, mixers, and pumps in automated process equipment.
It operates from a three-phase 380 to 480 V input, so it connects to standard industrial mains without a transformer. The drive delivers a continuous mechanical output of 3.0 HP, which corresponds to an electrical rating of 2.2 kW and provides headroom for typical 2 kW-class motors. An IP66 polycarbonate housing protects the electronics against water jets and airborne dust, allowing direct washdown mounting on production lines. For supervisory control, the embedded DeviceNet interface exchanges setpoints and diagnostic information with PLCs over a single fieldbus trunk. The decentralized layout places motor control close to the connected equipment, reducing the distance between the power stage and the motor. This arrangement is suitable for food, beverage, and chemical plants that require repeated cleaning and centralized monitoring.
An integrated 1A filter inside the line section limits conducted radio-frequency noise, allowing the drive to operate in environments that require Category C1 EMC performance. The power stage is backed by an extended 24 V external supply, which keeps the control circuits active during mains interruptions and supports orderly shutdown sequences. Wiring enters through a wall-mount box with metric threads, simplifying gland selection and providing suitable strain relief for incoming cables. The design targets processing applications and includes a corrosion-resistant standard coating for use near production equipment. A display connector accommodates handheld parameter panels, making parameter access straightforward when the unit is mounted overhead or in a confined location.
