FR-E Series
Downtime reduction



Streamlining the installation process







- Compatible installation size
The installation size was determined to assure exchangeability with the FR-E700 series. Installation interchange attachment options are available for facilitating replacement with the models of different size.
(The depth required for installation increases by 12 mm.)


Easy and fast wiring






- Control circuit terminal
- Spring clamp terminals have been adopted for control circuit terminals for easy wiring.
Furthermore, wires can be protected against loosening or contact faults due to vibrations during operation on a bogie or during transport. No additional screw tightening is required. - The removable control circuit terminal block facilitates replacement with a new one.

Troubleshooting supported by AI technology







- AI fault diagnosis
The inverter is connected to the engineering software FR Configurator2 (USB/Ethernet connection).
Maisart*1 (Mitsubishi Electric's AI technology) is integrated in the software to analyze data and help identify the cause of a fault*2 (this function is enabled during speed control).
This function enables the fastest troubleshooting procedure without requiring any special skills, which contributes to downtime reduction.
- *1: Maisart is Mitsubishi Electric's brand of AI technology. The name stands for "Mitsubishi Electric's AI creates the State-of-the-ART in technology". This means that it is using our proprietary AI technology to make everything smarter.
- *2: Diagnosable faults: Overcurrent trip, Overvoltage trip, Inverter overload trip (electronic thermal relay function), Motor overload trip (electronic thermal relay function). (other faults will be supported in the future.)



Continuing the operation during a trouble




- Emergency drive (Fire mode)
The inverter can continue driving the motor in case of emergency such as a fire, since protective functions are not activated even if the inverter detects a fault.
The operation can be switched to the commercial power supply operation at the occurrence of a fault which may cause damage of the inverter.


Quick reaction to troubles






- Power supply from USB port
With the power supplied from the computer (USB bus power connection)*3, parameters can be set using FR Configurator2 while the main circuit power supply is OFF.
Maintenance can be performed quickly and safely.
- *3: The maximum SCCR should be 500 mA. A PU connector cannot be used during USB bus power connection.

- 24 VDC input (FR-E8DS E kit)
Maintenance can be performed safely as the parameter setting and communication operation can be done while the main circuit power is OFF. (24 V external power supply operation)
When a fault occurs, troubleshooting is facilitated as the fault indication remains after turning OFF the main circuit power supply.
Turning ON the main circuit power during the 24 V external power supply operation switches the operation to the normal operation. Before the operation is switched, a reset is performed in the inverter.



Trouble analysis from a remote location







- Trace function
Users can read the data file in FR Configurator2 for graph display or send it by e-mail to someone away from the worksite, which facilitates the trouble analysis.
- Clock function
It is possible to synchronize the internal clocks of the devices that comprise the CC-Link IE TSN communication.
- *4: The clock does not run while the control circuit power is OFF. The clock needs to be set every time after turning ON the inverter power.
By using the real-time clock function with the optional LCD operation panel (FR-LU08) (when using battery), the clock keeps running even when the control power supply is turned OFF.
