■ Newly Developed Soft-PWM Control
Mitsubishi’s Soft-PWM switching system keeps noise to a minimum
(as low as a Mitsubishi FR-Z Series inverter).
Note: The default setting is Soft-PWM control.
Sample Motor Noise Data (With an SF-JR 4P 3.7kW Motor and a 2kHz Carrier
Frequency).
Highly Cost-Effective Inverters
Environmentally Friendly
■ Low Noise Operation Available
A higher carrier frequency can be used to reduce operating noise.
■ Can Handle Power Supply Harmonic
Restrictions
A compact, lightweight DC reactor (FR-BEL) can be connected to all
capacities.
■ EMC Filter
Use the optional EMC filter to help to comply with EMC standards.

Without Soft-PWM
Since the frequency components are
dispersed, the motor generates little
metallic noise and does not sound
unpleasant.
Since the frequency components are
concentrated, the motor generates a
grating metallic noise.
■ Globally Compatible with Worldwide
Standards
● Compatible with UL, CSA, and EN standards (eligible for CE
mark). (Models available soon.)
● Select either IP20 or IP40 construction.
■ Compatibility with 240V and 480V Power
Supply Now Standard
■ Full Line-Up of Capacities Available
The FR-E500 is the first line-up in its class to include 5.5kW and
7.5kW capacities, which extends the range to 0.1–7.5kW.
■ Compatible with Single-Phase Power Supplies
Compatible with single phase 100V and 200V as well as three-phase
200V and 400V power supplies. (Output is three-phase 200V.)
■ Compatibility with Data Communications Also
Standard
● We've added RS-485 communications functionality as standard,
so you can control operations via data communications once the
control panel is removed.
Note: An “off-the-shelf ” converter is needed for RS-232C communication.

Cable with built-in interface DAFX-CAB Series
Connector conversion cable DINV-485CAB
● The inverter can be run using PLC X and Y
instructions via CC-Link (compatible models
to be released soon), making programming
easy.
