Inverters-FREQROL-D800 Series Higher added values
Outstanding drive performance and various functions create higher added values
Supporting various speed commands<sup>Ver.UP</sup>
In addition to commands input from the operation panel, various other speed commands are supported, including those using the multi-speed operation by switches, JOG operation, RS-485 communication, and pulse train input.
The optimal speed command method can be chosen in accordance with the system specifications.
Improving productivity with shorter tact time by the enhanced regeneration function
Built-in brake transistorVer.UP
With the enhanced power regeneration capability (brake duty: 100% max.), deceleration time can be shortened.

- *1: The brake duty is 30% ED maximum when the lowest resistance value is used.
The brake resistor must have a sufficient capacity to consume the regenerative power.

Increased magnetic excitation deceleration
When the increased magnetic excitation deceleration function is used, the motor consumes the regenerative power and the deceleration time can be reduced without using a brake resistor.
The tact time can be reduced for a transfer line or the like.
For more precise processing<sup>Ver.UP</sup>
The maximum frequency of 590 Hz can be output under V/F control. (Up to 400 Hz can be output under other controls.)
The rotation speed can be set according to the material to be processed, and furthermore, stable high-speed rotation is possible.
It is best suited for machine tools used to cut or polish various new materials.

Supporting various motors
Driving an induction motor or synchronous motorVer.UP
Not only induction motors but also PM motors are supported for synchronous motor drive.
The auto tuning function enables operation of non-Mitsubishi Electric PM motors*2.
Even if the control method differs depending on the application, such as V/F control for fans and pumps or Advanced magnetic flux vector control for conveyors, the FR-D800 can switch between control methods, reducing the number of required spare inverters.

Stable operation under load variation
Advanced magnetic flux vector control
Selecting Advanced magnetic flux vector control enables stable operation in the lift application that requires high-torque in the low-speed range.

150%/0.5 Hz (5.5K or higher) - Speed fluctuation ratio*3: 1%
- Speed control range: 1:120
- *3: Speed fluctuation ratio =speed with no load - speed with rated loadRated speed×100 (%)
Improving work efficiency by powerful high-speed operation
PM sensorless vector controlNEW
The torque is not reduced in the high-speed range (up to the rated speed) during PM sensorless vector control as compared with operation using a stepper motor.
High-speed system operation improves the tact time.
The PM motor offline auto tuning*4 enables sensorless operation of other manufacturers' permanent magnet (PM) motors.
