- What is a permanent magnet (PM) motor?
A PM motor is a synchronous motor with strong permanent magnets embedded in its rotor. The two major PM motor types are: the interior permanent magnet (IPM) motor with its magnets embedded inside the rotor, and the surface permanent magnet (SPM) motor with its permanent magnets attached on the rotor surface.
- What is PM sensorless vector control?
The speed and magnetic pole positions, the two essential bits of information to control a PM motor, are detected without a sensor (encoder). The speed detection internally-performed in an inverter enables highly accurate control of a PM motor, almost as accurate as an AC servo system, without the need of a sensor (encoder)*5 . Combining with Mitsubishi MM-CF series IPM motors facilitates aspects of high-level control with no encoder such as “simple positioning”*6 and “zero speed torque”.

Easy maintenance for sensor (encoder)-less motor.
- No additional cables means less wiring space required.
- Improved reliability is obtained in unfavorable operating environments. (e.g. high vibration)
- PM motors are usually smaller and lighter than induction motors.

Taking motor performance to the max with Mitsubishi vfd FR-A800 series.

The cutting-edge auto tuning function.
The PM motor auto tuning function, which has been newly developed, enables sensorless operation of other manufacturers' permanent magnet (PM) motors. Operation with all Mitsubishi induction motors and PM motors, in addtion to induction motors and PM motors from other manufacturers*7 , is possible. That means you need less motors for spare and stocks. (With IPM motors other than MM-CF and PM motors manufactured by other companies, starting torque is limited to 50%, and simple positioning control and zero speed torque cannot be used even if tuned.)
*7: Tuning may not be available depending on its motor characteristics.

Mitsubishi frequency inverter is for Improved Equipment Reliability.
Reliable and secure maintenance.
In addition to the existing power supply input terminals (R1 and S1) of the control circuit, 24 VDC input is equipped as standard. The 24 VDC power supplied from outside can be fed to the control circuit locally, enabling the parameter settings, communication operation and safety maintenance without turning ON the main power.
Prevention of trouble with temperature monitoring:
The inverter is equipped with an internal temperature sensor, which outputs a signal when the ambient temperature is high. This facilitates the detection of rises in temperature inside the inverter following cooling fan malfunction, or rises in ambient temperature due to inverter operating conditions.

Quick reaction to troubles with Mitsubishi drive FR-A800 series.

- The operating status (output frequency, etc.) immediately before the protection function activates can be stored in the inverter built-in RAM with the trace function. Stored data (trace data) can be copied to a USB memory device, facilitating easy trouble analysis at a separate location by reading into the Inverter Setup Software (FR Configurator2).
- Clock setting is now available in addition to the already-available cumulative energization time. The time and date at a protective function activation are easily identified. (The clock is reset at power-OFF.) The date and time are also saved with the trace data, making the fault analysis easier. By using the real-time clock function with the optional liquid crystal display (LCD) operation panel (FR-LU08) (when using battery), the time is not reset even when the power supply is turned OFF.
Backup/restore.
The GOT can be used for backing up inverter's parameter settings and the data used in the PLC function of inverter, and the backup stored in the GOT can be used to restore the data in the inverter.

Eco-friendly factories.

The power consumption by motors is said to amount about the half of all power consumption made by the Japanese manufacturing industry. Factories can save more energy without dropping their production. Less energy and more production—the FR-A800 series will help you to get the both.
Energy-saving function tailored to system, application.
Check the energy saving effect at a glance.
- You can check the energy saving effect on the energy saving monitor:
- The measured output power amount can be output in pulses.
Reduce power consumption during standby:
- Control circuits other than those for power-related parts can be operated with 24 VDC power supplied from an external power source. Since the control circuit can use the external 24 VDC, other power control circuits can stay OFF while no driving is required, and that saves the standby energy.
- By turning the cooling fan ON/OFF based on the inverter status, wasteful power consumption during stoppages can be reduced.
Save energy with Optimum excitation control:
The excitation current is constantly adjusted to drive the motor in the most efficient method which leads to energy saving. For example, with optimum excitation control with motor load torque of 10% when using the SF-JR, motor efficiency has increased by approximately 15% over the previous V/F control method.
Effective use of regenerative energy (option):
Multiple inverters can be connected to the power regeneration common converter (FR-CV)/high power factor converter (FR-HC2) via a common PN bus. Regenerative power is used at other inverters, and surplus energy is returned to the power supply, resulting in energy saving. The 315K or higher models are inverter-converter separated types, which are suitable for power regeneration.
PM motor contributes to the energy saving in factories.
If the inverter is being used for an application requiring constant-torque, such as a conveyor, factory energy savings can be achieved by replacing your current induction motors with permanent magnet motors (PM motors). (Tuning is required for an IPM motor other than MM-CF, and for the PM motors of other manufacturers.)
Why is a PM motor so efficient?
- The current does not flow to the rotor (secondary side), so there is no secondary copper loss.
- Magnetic flux is generated by permanent magnets, so less current is required to drive a motor.
