Mitsubishi Electric has introduced a series of easy-installation space-saving free-standing cubicle drives. Incorporating the latest generation of energy-saving FR-F700 variable speed drives, the F700 FSU (floor standing unit) is designed to provide a total solution without the need, or costs, of building a special panel. The F700 FSU encompasses the range from 45 kW up to 630 kW and provides a cost effective ac-in, ac-out solution for IP20 stand alone use, such as in a control room. Assembly and installation usually takes less than an hour with the unit being delivered in easy to handle, pre-drilled sections.
The drive is suitable for a wide range of applications from fans and pumps, conveyors and hydraulics to compressors, pumps and blowers and is aimed at both retrofit and OEM users in manufacturing and building services.
The completed unit incorporates a dc choke for reduced harmonics and, if required, an optional high specification EMC filter to meet RF levels specified by EN 61800-3 standard Environment 2. The F700 FSU is for stand alone floor mounting (with an enclosed rear), can be wall mounted and comes in two sizes (1.65 m and 1.9 m).
As standard, the F700 unit incorporates an FR-DUO7 operator keypad that is quick and easy to use. The setting dial allows speedy entry of parameter values, with typical set-up being less than ten minutes. The unit also gives monitoring of I/O, power consumption and energy savings.
The latter derives from the pioneering Optimum Excitation Control that is unique to Mitsubishi Electric FR-F700 inverter drives. By ensuring that optimum flux is delivered to the motor at all times, the drives deliver power savings of around 10% across the speed range – more at lower speeds.
The F700 FSU incorporates a fitting point for an MCCB and further options include a keypad extension cable and Profibus, CC-Link and LonWorks communications.
