A comparison with the international market
demonstrates that in the frequency converter
segment, Mitsubishi Electric is building compact
devices with tremendous overload capability that
offer optimal performance. The new FR-S 540 is the
affordable solution for utilizations between 0.4
and 3.7 kW, whereby it is suitable for simpler
applications than the FR-E 540.
The entire 500-series really does speak the
same language: from the FR-S 500 and FR-A 540 all
the way to the FR-A 540 L, a standardised
operating concept is clearly evident, for both the
parameters and their significance are identical
throughout the 500 series. Specially programmed
software is compatible with the entire inverter
series, allowing the user to quickly put any of
the devices into operation and fine-tune them for
the tasks at hand.
Like the FR-S 520 S, this
device has a “digital dial” instead of a
keypad, simplifying the setting of application
parameters. Another advantage: the user is able to
limit access to the 12 most important parameters,
allowing the device to be put into operation more
quickly while eliminating possible sources of
errors. Mitsubishi Electric has also ensured the
optimal visualisation of the software functions
for the FR-S 540 – including power, voltage and
torque displays.
When integrating this device into
an automation system, an RS 485 serial interface
is standard equipment, permitting the networking
of up to 32 frequency converters.
If needed the user can also use
one of the external control units from our 500
series, to copy parameters for series-wound
machines or even larger systems, for example.
As was already the case with the FR-S 520,
the transistor power module is also equipped
with "automatic torque boost“ control.
