MITSUBISHI inverter FR-D720S series.
Voltage level: single phase 200V.
Frequency converter capacity: 0.2KW.
VVVF frequency control, vector control frequency conversion, direct torque control is a kind of AC - DC - AC frequency conversion.
The common drawback is that the input power factor is low, the harmonic current is big, and the DC circuit needs large energy storage capacity,
Renewable energy and can not be fed back to the power grid, which can not be carried out in the four quadrant operation HA-LFS11K1M4B To this end, the matrix type of AC - AC variable frequency arises at the historic moment.
Because the matrix type alternating current frequency saves the intermediate DC link, thereby, the electrolytic capacitor with large volume and high price can be omitted.
It can achieve a power factor of L, the input current is sinusoidal and can run in four quadrant, the power density of the system is large.
Although the technology is not yet mature, but still attract a large number of scholars in-depth study.
In fact, the quality is not the indirect control current, flux, but the torque is directly used as the control to achieve. Used for a common positive input module (3 line type).MITSUBISHI general purpose AC servo amplifier MELSERVO-J2-Super series.
Rated output: 30.0kw.
SSCNET interface.
Voltage: 3 phase AC400V.
Complete synchronization system with SSCNET high speed serial communication,
The communication cycle between the controller and the servo amplifier is the longest 0.888ms.
Such systems will be able to provide high reliability and high performance.
When connecting the servo system with SSCNET,
In the motion system, the parameters of the servo amplifier and the acquisition of the data will be displayed on the motion controller.
Connect a dedicated cable with an amplifier and a controller to form a SSCNET system.
This simple connection method reduces the routing time and helps to prevent noise.
Even in the MELSERVO-J2-SUPER series products using high resolution coding standards, the command frequency is no limit.
It is only necessary to add a battery on the servo amplifier, which can form the absolute value system.
Currently there are more than 1000000 high reliability SSCNET servo amplifier networks in use.
