Mitsubishi have released a new variable speed drive, the D700 series. Improved functions and device properties such as simplified cabling with the help of spring clamps, the integrated Digital Dial with LED display, improved performance yield in the low-speed range as well as the integrated emergency stop function make the FR-D700 the new standard in the ultra compact class. Mitsubishi D700 variable speed drives are available from Automation Systems & Control .
The FR-D700 inverter is especially advantageous for standard applications by virtue of its user-friendliness. It is suitable for both simple and sophisticated applications. Typical applications are feeder and conveyor drives, machining tools or gate and door drives.
This inverter actively monitors its own functional safety. If, for example, the fan RPM decreases to 50%, a pre-alarm is triggered. An internal measuring programme monitors the ageing of the capacitors and an operating hour counter enables the operator to plan the best time for servicing. Protection and overload functions like the phase failure monitoring system for both the input and output circuits ensure trouble-free operation.
The FR-D700 inverter is designed for a long service life. This is made possible by high-performance heat- resistant capacitors, cooling fans with sealed bearings and special lubricating grease. The flow of cooling air comes into contact only with the heat sinks and not electronic components. This ensures that no dust or dirt can collect on the components. The circuit boards are protected against aggressive environments with single or double layer conformal coating – another feature that ensures longer service life.
