WITH 11 million frequency inverter drives already sold, Mitsubishi Electric now introduce its latest generation of compact inverter, the FR-E700, and the ultra compact FR-D700 series.
In addition to additional features and improved performance, the new series is also more compact and easier to install.
The drives include an integrated USB port, an integrated, one-touch digital dial control with a display, improved power usage at low speeds, and an expansion slot compatible with cards from the 700 series.
The range includes intelligent functions for diverse applications.
A sensorless vector control system in the FR-E700 and FR-D700 series provides improved speed and torque performance.
This technology makes it possible to achieve increased speed and torque performance, even with motors without encoder feedback loops.
The drives also include an auto tuning function that can read necessary parameters directly from the motor in less than a minute, even when the motor is not running.
The range increases the maximum short-term overload capacity to 200% for three seconds for the FR-E700, and 0.5 seconds for the FR-D700 version.
The drives also feature improved torque and current limiting during start up, and deceleration ensures better protection for machines.
Applications like gate drives, hoists, cranes often need an additional brake to cope with suspended loads.
The FR-E700 series support connection of an external mechanical brake controlled by the inverter.
An integrated control unit with a one-touch digital dial on both inverter models gives the user direct access to important parameters.
In addition to entering and displaying parameter values, the integrated display is used to monitor and check operating values and alarm codes.
The FR-E700 and FR-D700 inverters can be connected to RTU Modbus and the FR-E700 supporting network systems like Profibus/DP, CC-Link, DeviceNet and Lonworks.
Additional functions can be added to the FR-E700 with option cards and I/O modules.
The range conforms to international standards including CE, UL, cUL, C-Tick, and GOST.
