MITSUBISHI ELECTRIC
FR-E 500 EC
Environmentally Friendly Operation
EMC compatibility
The FR-E 500 EC inverter regarding its elec
-
tromagnetic compatibility complies with
the European EMC directives. To meet
these standards specially adjusted com
-
pact noise filters (“foot print”) have been
developed for each performace range.
Additionally, for the single-phase inverter
FR-E 520S EC built-on filters are available.
These filters can be installed easily on the
rear side of the inverter into a prepared
compartment. There is no need for addi
-
tional room or extended dimensions.
Refer to page 23 for further details.
To limit the inrush current and reduce
mains conducted emissions the inverter

upon the inputs. A DC reactor can be
installed as well.
Standards
The devices of the FR-E 500 EC product line
are designed to be used world-wide with
-
out further effort or certifications.
앬
Compliant with world-wide standards
CE, UL, cUL
앬
Selectable sink or source logic
The logic for input and output signals
can be freely selected. The result is a
flexible and easy customisation of the
units to the needs of the world market.
앬
Extended rated input voltage
1~ 200–240 V; 50/60 Hz (FR-E 520S EC)
3~ 380–480 V; 50/60 Hz (FR-E 540 EC)
Tolerance: −15 %; +10 %
앬
Multi-language parameter unit
(8 languages) available as option
앬
Due to the integrated PID control the
frequency inverter for instance can be
used for temperature control without
further requirements.

tion of the connected components.
앬
MS-Windows compatible world-wide
standardised multi-language
parameterising software (VFD-Setup)
The FR-E 500 EC therefore is a world
product complying with all relevant
standards and easily adopting to the
according needs of a country.
Soft-PWM control
In addition to the conventional low-noise
mode, MITSUBISHI ELECTRIC has devel
-
oped its original Soft-PWM control that
suppresses acoustic noise and limits RFI
noise to a minimum.
The switchable PWM control facilitates a
motor noise as silent as whisper even at
low carrier frequencies. The diagrams
illustrate the difference.
In the upper diagram the frequency
pulse patterns are dispersed: The inverter
only generates little noise that might be
compared to the sound of flowing water.
The noise does not sound unpleasant.
In the lower diagram the frequency
pulse patterns are concentrated:
The inverter generates the typical grating
metallic noise.
