Instruction Manual
Product Overview
Mitsubishi Electric now introduces its latest generation of compact inverters, the FREQROL-
CS80 inverters. In addition to better features and performance than their predecessors, the
models in this series are also more compact and even easier to install. The improvements
include a 57% reduction in volume, high performance, ease of use and easy maintenance.
All the improvements make the FREQROL-CS80 an economical and highly-versatile solution
for a wide range of applications from wood processing to controlling fans and pumps.

Lineup
The applicable motor capacity is the maximum allowable capacity of the motor with
respect to a Mitsubishi Electric 4-pole standard motor.
World’s smallest class compact body
The FREQROL-CS80 compact size is achieved by the low heat generation design. Side by
side installation of these inverters is possible as long as the surrounding air temperature
does not exceed 40°C. Three FR-CS84-012-60 inverters can be installed in the same space
normally required for two conventional models which ultimately means space saving. A
DIN rail installation attachment (FR-UDA [][]) option can be used but this is excluded for
inverters FR-CS84-120 to 295.

High performance
Even with a 57% reduction in volume this inverter still offers high performance. Functions
available on this inverter include general-purpose magnetic flux vector control and auto
tuning functions. These functions ensure that these inverters can be used in applications
that require high starting torque, such as washing machines, agitators, and transfer
machines which includes conveyors, hoists, and elevators.
The high torque of 150% / 1 Hz is realized (when the slip compensation function is
valid).
Auto-tuning
With the “non-rotation” auto-tuning function the motor constant (R1) can be automatically
calculated.
There is also a brake unit connection which allows a brake unit to be connected using
terminal P/+ and terminal N/-. This is useful for applications that require regenerative
braking torque during deceleration, such as transfer machines and food machines. When
using the inverter with the brake unit, it is recommended the FR-CS84-050-60 inverter or
a higher capacity inverter is used.
Optimum excitation control continuously adjusts the excitation current to
an optimum level to provide the highest motor efficiency. For example, at 4% motor load
torque for a general-purpose motor, the motor efficiency under Optimum excitation
control is about 30% higher than the motor efficiency under V/F control. Optimum
excitation control is another option on this inverter. The excitation current is constantly
adjusted to its optimum value to drive the motor most efficiently. With a small load torque,
a substantial energy saving can be achieved.

Easy to use
This inverter has an easy-to-read operation panel. An optional LCD operation panel, the FR-
LU08 is also available. This panel can be connected using the separate parameter unit
connection cable (FR-CB20 []) with the operation panel connection connector (FR-ADP).
Another operation panel, the enclosure surface operation panel FR-PA-07 enables inverter
operation and monitoring of frequency setting from the enclosure surface.

FR-CS84-295-60
The parameter unit FR-PU07 features helpful settings such as direct input with ten-key pad,
operating the status display, and help function. Eight languages are supported and
parameter settings for up to three units can be saved.
A free trial version of software FR Configurator2 can be downloaded at Mitsubishi Electric
FA Global website. This software contains start-up functions which allow for a shorter
startup time with easy setup. The FR configurator2 software has the common design and
operability of MELSOFT Mitsubishi Electric FA products.
