Variable frequency drive MV6000

MV6000 series medium voltage variable frequency speed control systems, the new generation of high voltage (SM/AM) three-phase AC speed control device manufactured by our company, have following features:
◆ High performance vector control technology (SM/AM) of high precision and quick dynamic torque response
◆ Built-in PID regulator: Close loop running
◆ Compatible with vectorization V/F control, that is optimize V/F control and make the dynamic response approach the vector control level; gain better torque feature by low frequency aic torque boost
◆ Excellent low frequency compensation: By the advanced algorithm of dead area compensation and low frequency oscillation suppression, low frequency output performance will be better under vector and V/F control modes
◆ No stop after instantaneous power off and main circuit power off (1-5s) ensures the device is not affected by sudden power off
◆ Optimized overvoltage speed loss: Bus voltage close loop facilitates quick deceleration without overvoltage alarm
◆ Master-slave control: Multi-motor control of the belt conveyor
◆ Power consumption statistics of variable frequency
◆ V/F separation (suitable for power industry)
◆ One-drive-more control of bypass cabinet
◆ Braking energy balance: By software optimization on braking energy distribution, balance the braking energy on each power unit and lower overvoltage point
◆ AVR function for output voltage (Automatic Voltage Regulation): Control the output voltage accurately and improve the control performance of the motor
◆ Strong voltage adaptability, with a wide range of input voltage, applicable at home and abroad
◆ All-around rotating speed tracking makes the motor restart in rotating to guarantee continuity
◆ Synchronous switching (optional): Smoothly switch between the grid and variable frequency, decreasing impact on the grid and motor
◆ Multiple communication methods: MODBUS-RTU, PROFIBUS-DP (optional), Ethernet UDP (optional)
◆ Modularized design, convenient and simple maintenance
◆ The ventilating window mounted externally is convenient for dedusting and maintenance
◆ LCD display, touch buttons on the panel
◆ Double-loop redundancy of control power, cascading fault protection

Besides, the systems also has:
◆ Realtime parameters monitoring, realtime data recording, alarm and fault protection, fault find and waveform displaying
◆ Overload and overcurrent protection
◆ Phase loss protection
◆ Overvoltage, undervoltage, overtemperature and overspeed protection
