178B2124 Danfoss Variable Frequency Drives (VFD)

Part number 178B2124 from Danfoss, listed in Variable Frequency Drives (VFD). KKM Solutions quotes this part with pricing and availability confirmed per order.

The 178B2124 is a decentralized AC motor drive manufactured by Danfoss for the FCD 300 Micro Drives series. It is also identified under the product-type code FCD 300, meaning the power stage, control, and I/O are grouped in a single housing that mounts directly on the machine. By doing so, the unit removes long motor cables and eases cabinet load while delivering speed regulation to conveyors, mixers, and other motion elements found across automated processing lines. The drive accepts a three-phase supply of 3x380-480 V and converts it to a mechanical output of .50 HP . Its inverter section is rated at 0.37 kW , aligning with small induction motors that dominate utility equipment on modular machines. Networked control is handled through Profibus DP V0/V1 3 Mbaud , so a PLC can exchange setpoints and status bits without additional gateways. Conducted emissions are reduced by an integrated integral 1 A filter , helping the installation meet plant EMC limits. A display connector enables the plug-in service keypad for parameter access, and a standard coating protects internal assemblies from indoor industrial atmospheres. Mechanical and environmental characteristics round out the design. The die-cast housing carries an IP66 rating that blocks dust ingress and high-pressure wash-downs. Support electronics benefit from the Extended (24 V ext.) hardware option, which provides an auxiliary low-voltage supply for sensors and relays. Field wiring terminates in a wall-mount box with metric thread entries, simplifying strain relief and maintaining international gland compatibility. These attributes suit the drive for a processing application where decentralized placement, ingress protection, and modest power output must coexist within a compact package.
