INVT Goodrive350 advantage

Performance improvement
- Motor auto-tuning
* Asynchronous motor - eliminates the impact of the skin effect, improving the auto-tuning precision.
* Synchronous motor - performs auto-tuning on the counter-electromotive force, effectively avoids the impact of the initial value of the counter-electromotive force.

- DC braking
The current change is is smoother in the process of the motor entering DC braking from rotating, the current shock is weak and the current response is faster.

- Rotating speed tracking
In any of the control modes, the rotating speed tracking method brings the least current shock, and thus significantly improves the stability.

- High torque at low speed
Special I/F control, featuring constant current source, highly applicable to scenarios where multiple motors are to be driven simultaneously and high torque is required at low speed.



Data measured on a construction machinery site:



- Control performance
* New-type flux linkage observer, improving the stability of the high-speed control.
* New-type speed/current regulator, improving the current control result in quick start and reducing speed overshoot.
* New-type phase-locked loop, improving the stability of high-torque control.
* Compensation for output voltage phases and amplitude, improving the stability of high- and low-speed carriers.
* Adding the synchronous motor VF control mode based on reactive current control, The output current adapts to the load and the oscillation suppression algorithm.

Drive multiple motors
Applicable to drive various motors:



Combine different controls
More precise, stronger torque, speed and position control over motors



Torque and speed control performance - ensure stable mechanical operation, fast response and low torque control.



Keep running when power down
When the grid encounters a momentary power outage, the VFD can keep up running by using the fed-back energy within a certain period of time. It is highly applicable to chemical fiber and textile production lines and other scenarios where the device is required to run continuously.



Multiple braking modes to enable fast stop



Current wave in the SVPWM mode for asynchronous motors. Frequency: 10Hz, braking current: 100%



PMSM short-circuit braking wave. Acceleration time: 0.1s, deceleration time: 0.4s



Magnetic flux braking current wave in the SVPWM mode for asynchronous motors. Frequency: 50Hz, rated load: 100%
