APPROACH TO THE LEADING
DRIVE PERFORMANCE

The new series is equipped with the new state-of-the-art high-speed processor developed by Mitsubishi Electric. With better control performance and response level, safe and accurate operation is assured in a diverse range of applications.

The enhanced Real sensorless vector control and vector control serve the needs of all machinery types.
The vector control is available when a vector control compatible option is installed.

• *2The option (FR-A8AP, FR-A8AL, or FR-A8TP) is required.
  Speed response: The speed response indicates how fast the inverter follows the change in the speed command. (The larger value indicates the better speed trackability.)

PM sensorless vector control

● 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 Electric MM-CF series IPM motors facilitates aspects of high-level control with no encoder such as "simple positioning"^*6 and "zero speed torque".

*5Speed fluctuation ratio: ±0,05% (digital input)

*6Positional accuracy (with no load) of 1.5K and lower: ±1,8°, 2K and higher: ±3,6°

● 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

Induction motors and magnet motors can be combined freely

● 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 Electric induction motors and PM motors, in addition 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.)

*7Tuning may not be available depending on its motor characteristics.

●Low speed, high torque realized with SF-PR motor

By combining with Mitsubishi Electric's high-performance, energy-saving motor SF-PR, 100% continuous operation is possible from a low speed of 0,3 Hz for inverters of any capacity.

●Sharing the spare inverter

One spare inverter is enough for the two types of motors (IM and PM).
