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.

FR-CS84-295-60
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.

FR-CS84-295-60
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.

FR-CS84-295-60
High-speed communication is supported using a controller and RS-485 communication. The
inverter can be controlled and monitored via a network. Using the Mitsubishi inverter
protocol, MODBUS RTU protocol enables communication with a speed of 115.2kbps which
is faster than the 38.4kbs of a conventional model.
Once the automatic connection on the inverter is enabled, the inverter connects easily and
communicates with the GOT2000 series by connecting to the GOT using RS-485
communication. The easy to follow display improves the operability of the inverter.
Easy maintenance
There is a reduction in the wiring check time since the wiring can be checked by simply
lifting the control terminal cover, which makes maintenance work easier. The control circuit
terminals are spring clamp terminals which allow for easy wiring to the control circuit.
The main circuit terminals are screw terminals. Easy wiring is completed by inserting the
dedicated blade terminal of each cable. Without using the blade terminal, the loose wires
can also be connected using a flathead screwdriver.
The spring clamp terminals provide high reliability since the internal terminal contacts are
spring-type.
Therefore, these wires can be protected against loosening or contact faults due to vibrations
during operation on a bogie or during transport. It is maintenance free because no
additional screw tightening is required.
A specialised coating that conforms to IEC 60721-3-3 3C2/3S2 standards, covers the circuit
board to protect the board in hazardous environments and for improved environmental
resistance.

Supported Applications
This inverter supports a variety of functions that can be used in various applications.
Spinning Applications
Power failure time deceleration to-stop function
The motor decelerates to a stop without coasting when a power failure occurs or
undervoltage. Slack in the thread can be controlled even if there is a power failure.
Traverse function
The traverse function, used for the traverse axis of the spinning machine, prevents uneven
winding or collapsing.
Continuous operation function at instantaneous power failure
Even in the event of an instantaneous power failure, motor operation continues without
coasting and production is maintained.

FR-CS84-295-60
Conveyor applications
Communication operation (RS-485 communication)
Conveyor belts can be controlled individually by using multiple inverters. Automatic
operation is possible by collectively managing multiple inverters.
Increased excitation deceleration
The deceleration time can be reduced without using a brake resistor. The tact time can be
reduced to a transfer line or equivalent.
S-pattern acceleration/deceleration
An S-pattern is maintained from the present frequency to the target frequency; therefore it
is possible to reduce shock during acceleration/deceleration and prevent load shifts.

FR-CS84-295-60
Fan and pump applications
PID (Proportional, integral, derivative) control
The flow rate and air volume are controlled by an inverter. It is possible to regulate the flow
rate and the air volume so that they stay at a preset level.
Optimum excitation control
This control enables the motor efficiency to achieve its optimum. More energy saving is
possible in applications with variable load torque characteristic such as a fan and a pump.
Adjustable 3 points V/F
The optimal V/F pattern matching the torque characteristics of the facility can be set.

FR-CS84-295-60
Fountain applications
Continuous operation function at instantaneous power failure
Even in the event of an instantaneous power failure, motor operation continues without
coasting and the fountain’s operations are undisturbed.
General-purpose magnetic flux vector control Brake unit connection
A variety of fountain displays are possible by connecting a brake unit which allows high
starting torque and improved braking efficiency during deceleration under general-purpose
magnetic flux vector control.
Multi-speed function (Up to 15-speed switching operation)
Operation speeds can be preset via parameters. Motor speed to meet the height
requirements of the fountain can be set and easily changed.

FR-CS84-295-60
Wood processing machine applications
Power failure time deceleration to stop function
The motor decelerates to a stop without coasting when a power failure occurs or
undervoltage. This function is useful for stopping the motor during a power failure to
prevent danger.
Continuous operation function at instantaneous power failure

Operation continues and the overcurrent alarm is not activated even if there is a sudden
change in load during the cutting of food.
General-purpose magnetic flux vector control
Depending on the type of ingredients, with the right amount of low-speed torque, it is
possible to regulate a suitable speed for food production.
Power failure time deceleration to-stop function
The motor decelerates to a stop without coasting when a power failure occurs or
undervoltage a predefined value. This function is useful for stopping the motor during a
power failure to prevent danger.
