Main controller DSP
The main controller chip uses TI's TMS320 F28335 digital signal processor, the device has 150 MHz high-speed processing capability, 32-bit floating-point processing unit, 6 DMA channels, support ADC, McBSP and EMIF. With up to 18 PWM outputs, six of them are TI's more accurate PWM outputs (HRPWM) and 12-bit 16-channel ADCs. Thanks to its floating-point calculation unit, users can quickly write control algorithms without having to spend too much time and effort on decimal operations, with an average performance improvement of 50% over the previous generation DSPs. At the same time, the application of better control algorithm, so that the waveform of the inverter running at low-frequency current and output harmonics have a significant increase.

Advanced functions
Synchronous transfer function:
Using phase lock loop technology to adjust the output of the drive, make the frequency, phase position and amplitude match those of the network. Achieve switching motor power from medium voltage drive to the network power (bypass mode) or vice versa (drive mode).

Flying start:
Also called “speed start”, when the motor is still rotating, the drive will automatically estimate the motor speed, and output the same voltage waveform with the motor frequency. When start, current is limited within the rated current, this will not cause over current problem.
Used when the drive automatically restarts after power loss, or Motor switch from network running to drive mode running.
network waveform
Instant power loss:
When grid voltage drop or power off for less than 1 .000 ms, VFD can run without stop to support process at site.
Torque boost:
Increasing the output voltage at low frequency, to boost the motor torque when running with low speed. The torque boost function supports high breakaway torque applications and guarantees a smooth start of the load.
Master-slave control:
Supporting multiple VFD system, with several motors running on the same load such a mills or conveyor belts. The VFD analyzes torque and load to balance motors speed and torque.
Double winding motor control:
Double winding motor has higher PF and efficiency, smaller loop circuit increase system capacity. VFD driving the double winding motor can realize full speed with half load, half speed with full load, improve system stability.
Power cell braking function:
This function enables high braking torque at low speed and guarantees a quick stop time if required.
Neutral point shift:
In case one power cell is internally bypassed because of a fault, the other power cells can adjust the output voltage to keep a balanced output voltage, by change phase position to maintain continuous running.
Cloud monitoring
MV drive connected to the server monitoring platform by wireless or wired network, sending real time data to server. Other mobile devices can receive internal data of the server at the same time to monitor real time running condition of the MV drive. By using monitoring the platform or mobile devices, users can analyze parameters, identify problems and diagnose the products fault from remote. At the same time, by using the panoramic camera and voice system, users can instruct technicians from remote to operate on site.
Interface board
The core of the new interface board is S7 .200 SMART CPU, the module comes standard with Ethernet interface, support Siemens S7 protocol, TCP / IP protocol, effectively supporting a variety of terminal connections. In addition, the CPU module is integrated with one RS485 interface, able to communicate with the third-party equipment such as the MV drive and touch screen. At the same time, it is equipped with expansion CM01 signal board to realize RS232 / RS485 free communication and support profibus and Ethernet TCP / IP communication protocol.
Interface logic controller
Interface logic controller uses a standard Siemens S7200 smart PLC as the core component, and this PLC is equipped with Siemens dedicated high-speed processor chip – its basic instruction execution time can be up to 0.15 μs. 24 DI, 16 DO, 4 AI, 4 AO have been selected for use according to the MV drive requirements, so it can guarantee adequate interface and ensure fast processing.
Parameters downloading and uploading
System and motor parameters can be easily downloaded and uploaded with a windows based software tool. The software provides an advanced service functionality and guarantees the correct parameter settings after the replacement of components.
