Mitsubishi Electric, the Automation company that introduced Variable Frequency Drive technology advancements such as All digital drives in the Z200 series in 1989 Direct user setup conﬁguration using the PU01 in 1989 “Micro” drive in the Z024 series in 1993 Sensorless ﬂux vector control in the A200E series in 1994 is proud to present its latest generation of high functionality, general purpose Variable Frequency Drives, the A700 Series. Designed and manufactured to follow the corporate policies of highest quality standards in the industry, ease of use and ever increasing functionality, the A700 is truly the drive of choice for the most demanding applications. With over 1.5 Million Variable Frequency Drives manufactured in 2007 alone and an installed base of over 18 Million, Mitsubishi Electric is truly the automation world’s leader for Variable Frequency Drives.
Mitsubishi Electric’s RSV technology gives you class-leading power, control and ﬂexibility.
What makes RSV (Real Sensorless Vector) control special? A700 stores a ‘map’ with the key motor characteristics in its memory and calculates the voltage needed to produce the necessary shaft torque and an output frequency which will keep the magnetizing ﬂux and torque producing ﬂux at right angles to each other – this is crucial to emulating DC drive/ motor performance.
RSV’s secret lies in new ‘Magnetic Flux Observer’ ﬁrmware that calculates the magnetic saturation level of the motor and further ‘trims’ the output voltage to compensate for it; by avoiding motor ‘over-ﬂuxing’, a wider speed range and smoother low speed operation of the motor than ever before is ensured. Speed Control with or without torque limit allows 200:1 Speed range, driving or overhauling* Open Loop Torque Control, including torque at zero speed * Regenerative or dynamic braking accessory may be needed depending on drive type and application
