178B1398
by Danfoss
The 178B1398 is an AC variable-frequency drive manufactured by Danfoss within the FCD 300 Micro Drives series. Intended for installation directly on a machine frame, the unit converts fixed-frequency three-phase power into a regulated output that governs motor speed and torque. By locating the control electronics close to the motor, wiring runs are shortened and cabinet space is conserved, making the drive a practical choice for distributed control zones in conveyors, mixers, and other continuous-process equipment.
The drive operates from a supply of 3x380-480V and can deliver up to 1.5 kW, which equates to a mechanical shaft capability of 2.0 HP. An enclosure rating of IP66 protects the inverter against dust and high-pressure washdown encountered on plant floors. Communication with higher-level controllers is available through Profibus DP V0/V1 12 Mbaud, allowing remote parameter access and alarm reporting without additional gateways. A standard display connector supports clip-on keypads for local commissioning, while internal monitoring circuits supervise temperature and current to maintain safe operation during extended processing duty.
Several construction details reinforce suitability for a Processing Application environment. Input conductors pass through a With integral 1A filter that suppresses conducted emissions to meet EMC limits. The hardware package is classified as Extended with brake, providing a built-in DC brake function for rapid motor stopping when the process sequence demands it. Power and signal wiring enter through a Wall mounted box, metric threaded terminal arrangement that eases sealed conduit installation. A standard protective coating resists airborne moisture, and the product type remains consistent with the broader FCD 300 line, ensuring common parameter structure across decentralized drive nodes.
