Why can the inverter 
save energy?

•Achieved a higher level of energy savings during acc./dec. to say 

nothing of during constant speed.

•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.

•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)

•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.

Deceleration

Reacceleration

When power is restored during deceleration

•Restart can be made without stopping the 

motor when the motor is coasting due to an 
instantaneous power failure.

•Smoothly restarts a motor that is rotating even in 

the opposite direction due to the windmill effect.

•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.

•Switchover to commercial power-supply operation is 

simple using R1 and S1 terminals of the control circuit 
and commercial power-supply switchover sequence.

•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

•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.

•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.

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.)

Parameter setting for multiple inverters is simple by 

copy with the operation panel.

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.

•

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)
