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.

(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.
*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.
(2) Automatic parameter setting for speci c applications
•Simple parameter setting (Pr.79 Operation mode selection)
•Communication setting for Mitsubishi HMI (GOT)
•Rated frequency change (60Hz → 50Hz)
(3) Spring clamp terminals

•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.

(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
•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

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.
(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.)
•Supports small loads (auxiliary contact)
•Supports many international regulations as standard
Optimum for Fan and Pump Applications
(1) Enhanced PID control
•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
•To use various types of detectors: PID set point and measured value

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.
