Upgrade of the renown Optimum Excitation Control!!
•Achieved a higher level of energy savings during acc./dec. to say
nothing of during constant speed.

The effect of energy savings is obvious
•The effect of energy savings can be confirmed using the
operation panel, output terminal (FM, AM terminal) and
via networks with the newly developed energy saving
monitor.

•Possible to set the torque
pattern that is optimum for the
machine's characteristic
•Possible to expect even more
energy savings with optimum
excitation control and optimum
V/F pattern working together
(2)
Enhanced PID function
•Energy savings in low speed region ... PID shutoff (sleep control) function
•Shorter PID startup time ... PID automatic switchover function
•Monitor of set point/measured value/deviation possible ... PID monitor
•Convenient for HVAC usage ... forward/reverse operation switchover
is simple with an external signal
•Corresponds to a wide range of detectors ... set point and measured value
for PID input can either be voltage (0 to 5V/0 to 10 V) or current (4 to 20mA)
Easy operation

Adoption of the original operation continuation
with the setting
dial of the
at instantaneous power failure function
operation panel
•Operation continues without
the motor coasting when an
instantaneous power failure
occurred in fan and blower
applications.
*The inverter may trip and the motor may
coast depending on the load condition.
RELIABLE
EASY
(1)
Operating life of parts are further lengthened
•Adoption of newly developed long life cooling fan
Longer operating life is further enhanced with the use of ON/OFF control of cooling fan.
•Adoption of long life capacitor
A capacitor with specification of 5000 hours at 105˚C ambient temperature is adapted.
*1 Ambient temperature: yearly average 40˚C (free from corrosive gas, flammable gas, oil mist, dust and dirt)
Since the design life is a calculated value, it is not a guaranteed value.
*2 Output current: 80% of the rated current of Mitsubishi standard 4P motor
(2)
State of the art longevity diagnostic method
•Degrees of deterioration of main circuit capacitor, control circuit
capacitor or inrush current limit circuit can be diagnosed by monitor.
•Trouble can be avoided with the self-diagnostic alarms* that is
output when the life span is near.
*Any of alarm for main circuit capacitor, control circuit capacitor, inrush current limit
circuit and cooling fan can be output.
(3)
Maintenance timer
•Maintenance timer output function can also inform of
maintenance time for peripheral equipments.
•Average output current value and maintenance timer value are output as pulses.
(5)
Improved workability
Easy replacement of cooling fan
•
¥The installation position of the cooling fan is in the
upper portion of the inverter.
Fan replacement is easily done without having to
remove the main circuit wires.

• Wiring is easy with the combed shaped wiring cover
¥Wiring cover can be reinstalled after wiring .
(200V class 22K or less, 400V class 30K or less)

Regeneration avoidance function
•Possible to avoid regeneration overvoltage alarm by
automatically increasing the frequency and continue
operation if the fan happens to rotate faster due to
the effect of another fan in the same duct.
(7)
PTC thermistor input
•Protection of the motor can be certain since the
built-in PTC of the motor can be input directly in
addition to the electronic thermal relay function.

(design life of 10 years* )
circuit terminals can be exchanged.
The removable terminal block of the FR-
F500 series can be used.
(The terminal block of the FR-F700 series is compatible with
that of the FR-F500 series.
Note that some functions of the FR-F700 series are restricted
when using the terminal block of the FR-F500 series.)

C Possible to copy parameters with operation panel
•
¥Parameter setting for multiple inverters is simple by
copy with the operation panel.
• Alarm history
¥Alarm history (alarm details and frequency, current, voltage
D
and cumulative energization time at time of alarm
occurrence) can be displayed on the operation panel and
the cause of a trouble can be checked.(up to 8 past alarms)
