Product Description:

The Danfoss model FCD 307 functions as a micro drive that provides frequency control with a specified limit. The manufacturer develops multiple parts for heavy industries to meet industrial needs.

The FCD 307 micro drive works across a wide span of 0.2–132 Hz and 1 to 1000 Hz frequency ranges which aids in ensuring stable operation for multiple industrial motor applications. Output frequency resolvability is set up to 0.013 Hz work band by allowing flexible frequency corrections consistent in their resolution. It can repeat it back to precise start and stop functions using terminals 18 and 19, and will keep this accuracy plus or minus 0.5 milliseconds by providing a process-synchronizing capability. The open-loop speed range is defined as 1 ratio 15 of synchronous speed that aids in providing controlled motor handling even in the presence of changing load conditions. The unit enclosure has an IP66 and NEMA 4X rating that features an indoor protection level that allows safe operation in industrial automation settings under dust and moisture conditions. The drive has been tested to 1.0 g vibration further helping to confirm mechanical stability during operation.

The FCD 307 micro drive operates reliably under a relative humidity range of 5% to 85% without compromising functionality. For thermal considerations, the maximum ambient temperature under IP66 classification is 40 degrees centigrade with a 24-hour average cap at 35 °C for safe working limits in factory settings. Its installation is suitable up to 1000 meters above sea level by keeping stability within altitude-defined limits. The one-year warranty of exchange by the Wake Industrial is supplied for this unit if an issue occurs.
