Compact Design
The foot print is the same as the Mitsubishi FREQROL-E520.
(400V class installation area has been unified to 108mm(128m.)
The height dimensions for all capacities have been unified to 128mm,
making panel layout easier.
5
Environment Awareness
The popular Soft-PWM control is incorporated as standard.
An increase in noise can be reduced, and noise can be suppressed to a minimum.
Reactor connection to aid harmonic suppression.
The compact and lightweight DC reactor (FR-BEL) can be connected.
Connect an AC reactor (FR-BAL) when using the single-phase 100V class.
6
Easy Maintenance
The cooling fan can be replaced easily due to a
simple cassette design. By setting the fan "ON-
OFF control", operation with an extended life
can be realized. (The ON-OFF control is set as
the default.)
Wiring space is secured and the wiring work ef-
ficiency is enhanced by incorporating an expan-
ded front cover and comb-type wiring cover.
7
Global specification
Compatible with UL, cUL and EN (CE Mark).

Other Handy Functions
Terminal function (multi-speed 15 of speeds, error
reset, output stop, etc.) can be selected
In-rush current suppression circuit is standard for
all capacities
PID control
4 to 20mA input
Sink/Source logic is selectable

By incorporating Mitsubishi's original and newly
developed "automatic torque boost control", a max-
imum 150% torque at 6Hz is possible.
The need for torque boost setting can be eliminated
and the current during no load can be controlled.
Example speed-torque characteristics using newly
developed automatic torque boost control is shown
on the left.
(For SF-JR 4P 0.75kW motor)
