Evolution of the inverter for fan and pump applications, energy savings for buildings and factories as a whole Evolution of the inverter for fan and pump applications, energy savings for buildings and factories as a whole
[Ex. of Blower Operation Characteristics] [Ratio of Motor Power Consumption during Acc./Dec.]
•Achieved a higher level of energy savings during acc./dec. to say
nothing of during constant speed.

(1) Upgrade of the renown Optimum Excitation Control!!
•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.
(2) The effect of energy savings is obvious

(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)
(3) Adoption of the original operation continuation
at instantaneous power failure function
•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.

•Restart can be made without stopping the
motor when the motor is coasting due to an
instantaneous power failure.
(4) Restart after instantaneous
power failure function
•Smoothly restarts a motor that is rotating even in
the opposite direction due to the windmill effect.
(5) Flying start
•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.

Regeneration avoidance function
•Switchover to commercial power-supply operation is
simple using R1 and S1 terminals of the control circuit
and commercial power-supply switchover sequence.
(8) Commercial power-supply

•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.

•Adoption of newly developed long life cooling fan (design life of 10 years* 1 )
Longer operating life is further enhanced with the use of ON/OFF control of cooling fan.
•Adoption of long life capacitor (design life of 10 years* 1, 2 )
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
(1) Operating life of parts are further lengthened
•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.

State of the art longevity diagnostic method
•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.
(3) Maintenance timer
(4) Update is also easy
¥ When exchanging the inverter, the control
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.)
• Removable terminal block

¥ Wiring cover can be reinstalled after wiring.
(200V class 22K or less, 400V class 30K or less)
• Wiring is easy with the combed shaped wiring cover
¥ Parameter setting for multiple inverters is simple by
copy with the operation panel.
• Possible to copy parameters with operation panel
(5)
Improved workability
¥ 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.
• Easy replacement of cooling fan
¥ Alarm history (alarm details and frequency, current, voltage
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)
