1. Quick Setting using Setting Dial
-
The frequency and
parameters etc. canbe set with a few simple steps.
-
Easily set values : turn
quickly to greatly change the value, and turn slowly to finely
adjust the value.
-
Accurate settings can be
made with the new notch-type "clicking" feel.
2. Simple Operation
-
As the default, the
parameters that can be set have been grouped into the minimum
required twelve parameters. Thus, parameters can be managed easily.
-
The modes can be changed
between the PU and external operation modes just by pressing the PU/EXT
(operation mode changeover) key. The current operation mode can be
confirmed with the status display LED.
-
The set frequency and the
output current value can be monitored just by using the setting dial
(set frequency monitor) or SET key (output current value monitor).
(When in the monitor display state.)
3. Automatic Torque Boost Control
-
By incorporating
Mitsubishi's original and newly developed "automatic torque boost
control", a maximum 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)
4. 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 128 mm. 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 efficiency is enhanced by incorporating an
expanded front cover and comb-type wiring cover.
7. Global specification
8. Other Handy Functions
-
Therminal 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
