Introducing the
Mitsubishi magnetic
contactor
• Offers a selection of small frames
• Offers a line-up of safety contactors
• Supports small loads (auxiliary contact)
• Supports many international regulations as standard
Refer to page 68
for the selection.
Flexible
installation
Wire and Space Saving
(1) A lineup of Filterpack models available
•The power factor improving DC reactor, common mode choke (line
noise filter), and capacitive filter (radio noise filter) are all essential for air
conditioning applications, and all of these are included in a Filterpack.
The Filterpack inverter models (FR-F7

0PJ-

F) are also available. The
option wiring, which was necessary in the past, is no longer required.
•A Filterpack allows flexible installation and various layouts in the
enclosure. Smaller space is required for installation.
•Less wiring and smaller space also enable compliance with the Harmonic
Suppression Guidelines, the Architectural Standard Specifications
(Electrical Installation) , and the Architectural Standard Specifications
(Machinery Installation) (2013 revisions)
in Japan.
(2) Space saving by the side-by-side installation
•Side-by-side installation is possible *

and requires less space.
A DIN rail installation attachment (FR-UDA

) option can be installed.

*1 : The area required for the separate installation of power factor improving DC reactor, common mode
choke (line noise filter), and capacitive filter (radio noise filter) with clearance around them.
*2 : Keep the surrounding air temperature of the inverter at 40 ° C maximum.
Side-by-side installation is not available for Filterpacks.
Easy Operation and Maintenance
(1) Quick setting using the setting dial
•The adaptable scroll speed setting dial
allows for quick jumps or precise
increments based on turning speed.
•The non-slip treatment was applied to the
setting dial for easier turning.
(4) Longer life parts
•The service life of the cooling fans is now 10 years * 2 . The service life
can be further extended by ON/OFF control of the cooling fan.
•Capacitors with a design life of 10 years *

are adapted.
(Surrounding air temperature of 105ºC for 5000 hours). With these
capacitors, the service life of the inverter is further extended.
*2 : Surrounding air temperature: Annual average of 40ºC (free from corrosive gas, flammable
gas, oil mist, dust and dirt). The design life is a calculated value and is not a guaranteed
product life.
*3 : Output current: 80% of the inverter rating.
(5) The leading-edge life diagnosis function
(2) Automatic parameter setting for specific applications
•Simple parameter setting (Pr.79 Operation mode selection)
•Communication setting for Mitsubishi HMI (GOT)
•Rated frequency change (60Hz
→ 50Hz)
(3) Spring clamp terminals
(control circuit terminals)
•The degree of deterioration of the main circuit capacitor, control
circuit capacitor, and inrush current limit circuit
can be diagnosed on the monitor.
•Using the self-diagnosis function, the part life warning *
4
can be output. With these warnings, the self-diagnosis
function prevents troubles from occurring.
* 4 : A warning is output when any of the main circuit capacitor, control circuit
capacitor, inrush current limit circuit, and cooling fan reaches its specified output level.
Spring clamp terminals *

are adopted as control circuit terminals.
Spring clamp terminals are highly reliable and can be easily wired.

(6) Enhanced communication function
•The Mitsubishi inverter protocol and MODBUS
®
RTU are selectable.
•The speed of RS-485 communication has been improved.
(Communication at 38.4kbps is available.)
*1 : The control circuit terminals are screw terminals.
Optimum for Fan and Pump Applications
(1) Enhanced PID control
(2) Regeneration avoidance function
The operation frequency is automatically increased to prevent the
regenerative overvoltage fault from occurring. This function is useful
when a load is forcibly rotated by another fan in the duct.
(3) Automatic restart after instantaneous power
failure function / flying start function
After an instantaneous power failure, the operation is re-startable from
the coasting motor speed.
Even if the rotation direction has been forcibly reversed, the operation
can be smoothly restarted in the original direction.
(Example: Water-cooling pump for a showcase)
•To save energy in low-speed operation: PID output shutoff (sleep) function
•To shorten the start-up time of PID control: PID automatic switchover function
•For air conditioning applications: Forward/reverse rotation switching
by external signals
•To use various types of detectors: PID set point and measured value
outputs in voltage (0 to 5V / 0 to 10V)
and current (4 to 20mA)
The fan is rotated by the external force.

Sudden change
of rotation
The motor can be started smoothly even after the motor was
rotated by the external force (coasting).
This function can be set enabled by changing
Pr.57 setting.
Parameters to adjust the acceleration time at a restart (Pr.611), to
detect the fan rotation direction (Pr.299), etc. are also available.
We need smooth start-up

OV trip
The trip does not occur and
the operation continues.
When the external force accelerates rotation of the running motor
(regeneration), the motor may trip due to the overvoltage.
The regeneration avoidance function is available to increase the
frequency and avoid the regenerative condition.
This function can be set enabled by changing
Pr.822 setting.
Parameters to start the regeneration avoidance operation (Pr.883)
and to adjust the response level (Pr.886) are also available.
We need continuous operations
without being interrupted by the
overvoltage protective function
(E.OV).
Use the
regeneration avoidance function.
