Mitsubishi FR-F700

More energy savings with Mitsubishi frequency inverter FR-700 series.

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.

Mitsubishi drive FR-F700 series is ideal for pumps and fans.

Adjustable 5 points V/F.
- 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.
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).
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.

Restart after instantaneous power failure function.
Restart can be made without stopping the motor when the motor is coasting due to an instantaneous power failure.
Flying start.
Smoothly restarts a motor that is rotating even in the opposite direction due to the windmill effect.
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.
Commercial power-supply switchover sequence.
Switchover to commercial power-supply operation is simple using R1 and S1 terminals of the control circuit and commercial power-supply switchover sequence.

Mitsubishi vfd FR-F700 series - Long life and simple maintenance. 

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.
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.
Update is also easy.
When exchanging the inverter, the control circuit terminals can be exchanged. The removable terminal block of the FRF500 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.)

Free of environmental worries with Mitsubishi frequency inverter FR-700 series.

Reduction of electromagnetic noises.
- Inverter noises have been reduced with the adoption of new technologies.
- Newly developed noise filter (EMC filter)
- Because of the built-in EMC filter, the inverter itself can comply with the EMC Directive.

- Because of the built-in capacitive filter and zero-phase reactor (55K or less), connecting the optional DC reactor to the inverter will comply with the electric installation work common specification and machine installation work common specification (2001) written under the general editorship of the Japanese Ministry of land, infrastructure and transportation.
Countermeasures for harmonic current output.
- Small AC reactor (FR-HAL) /DC reactor (FR-HEL).
AC reactor and DC reactor options for the control of harmonics current output has been miniaturized.
- Connection with high power factor converter (FR-HC/MT-HC) is possible.
Connection is possible to high power-factor converter for effective suppressions of power-supply harmonics (coefficient K5=0).

Mitsubishi drive FR-F700 series enhanced network.

RS-485 terminal is standard equipped.
- RS-485 terminals are available in addition to the PU. connector. RS-485 communication can be performed using the operation panel or parameter unit. Since terminals for input and output are provided separately, multi-drop connection is easily done.
- Modbus-RTU (Binary) protocol has been added for communications in addition to computer link.
Possible to correspond with major networks.
Possible to connect with LONWORKS, CC-Link Ver.1.1 and Ver.2.0, DeviceNetTM and Profibus-DP when used with communication options.
