The new FR-A700 frequency inverters combine innovative functions
and reliable technology with maximum power, economy and
flexibility. The FR-A700 is particularly well suited for demanding
applications like cranes and lifting gear, high-bay warehousing
systems, extruders, centrifuges and winding machines. What can you expect from Mitsubishi FR-A700?Precision without encoders Even without encoders the FR-A700 continuously calculates the
optimum magnetic flux for every operating state. This now makes it
possible to use inverters for many applications that were
previously the exclusive domain of DC or closed-loop vector drives. Ultra-precise speed and torque When operated with an encoder, the FR-A700 drives impress with
ultra-precise speeds across the entire control range (precision
±0.01 %) and extremely exact torque control (±10 % precision and ±5
% repeatability).
Autotuning This new generation of inverters has an autotuning function that
can obtain all the necessary specifications from the motor in less
than a minute, even when the motor is not running. Network capabilities It comes with both a USB port and a connection for Modbus-RTU as
standard equipment. Support is also available for Profibus,
CC-Link, CANopen and the SSCNET III motion control network. Self-diagnostics prevent downtime This inverter actively monitors its own functions. For example, a
pre-alarm is triggered automatically if the fan performance drops
to 40 %. Long service life guaranteed Mitsubishi Electric frequency inverter drives are known for their
long service life, however the FR-A700 sets even higher standards
in this area. Its key components are designed for a life of over 10
years. Comprehensive PLC expertise The integrated PLC functions of the FR-A700 series enable precise
configuration for individual application needs. In addition to
this, the inverter can even control simple applications itself
without any support from other controllers. User-friendly operation Setup is performed with the FR Configurator program, which can
also download, store and document application data. Oscilloscope
and machine analysis functions help the user to optimise the drive
system. Data and settings from the predecessor series can be
imported directly and converted for use in the new models. Four overload ranges The FR-A700 fully supports four overload ranges, which makes it
very easy to select the right inverter for every application. Specifications | SLD (super light duty) | LD (light duty) | ND (normal duty) | HD (heavy duty) | |
