Description
INVT GD5000 series medium voltage frequency drive was designed easy operation, economic and intelligent process control, with phase shift transformer and power cell parallel design, realize high efficiency and power factor, less harmonic combine with IEEE519.
The general series medium voltage VFD suits most light duty and heavy load, with advanced AVR and LVRT function, suit wide range voltage vibration, higher overload ability more reliable, support system bypass and power cell bypass, the control cabinet build UPS support data download even power off, The medium voltage drive has flexible terminals, support Modbus, Profibus-DP and various communication methods, easy connect to DCS system, or INVT IoT. General 2 quadrant medium voltage drive suitable applications such as Centrifugal pumps, fans, and compressors, screw compressors, blowers, refiners, mixers, extruders, belt conveyors, mill pressers, kilns, mills, hot gas expanders, etc.
Features:
1. Three Control modes
- High performance V/F control. (Fans, Pumps, Air compressors, etc).
- Open loop vector control. (Belt conveyer, mill drive, fibrizer crusher, etc.)
- Close loop vector. (Applicable to internal mixer, hoister machine, etc.)
2. Multiple types of motor drives
- Support Asynchronous motors
- Synchronous motors (Include PM synchronous motors)
3. LVRT Low Voltage ride through
- Wide voltage anti-interference capability. The system has AVR function for stable system output when the bus voltage fluctuates frequently.
- No stop when instantaneous power off, during running, the system will not stop after power off in the set time.
- Can be set when power o
4. Full Brand Speed Tracking
- Accurate tracking in the current rotating speed and direction of the motor without installing speed sensor, automatic starting can be set from 0 -3600 seconds.
5. Flying start
- During running, VFD will not stop after a short time power off, power off time no above 5s, motor continue running after speed tracking.
6. Multiple unit bypass modes
- The same level bypass, when one unit is invalid, bypass it and continue to run
- Support Neutral point drifting bypass, CPU smart calculate to ensure output stable and balance
7. Excellent Low Frequency Control
- Advanced dead area compensation technology, good low frequency waveforms; Optimized algorithm of low frequency oscillation suppression, no motor resonance
8.
Master-slave control mode
- Multi-motor drive system, realize multi-motor coordination control and obtain power balance.
- Flexible grid connection, support 1 VFD drive more motors.
- Optical loop connection, max support 16 drives in master-slave system.
9. Heat Dispersion Simulation
- With advanced heat simulation technology, high reliable structure design for heat dispersion.
- System and cabinet use unique air flue, reduce dust accumulation.
- PCB/PCBA duel sides covered with conformal coatings, excellent corrosive property to raise IP level.
10. Rich bus interfaces
- Support various communication protocols including Modbus, Profibus-DP, Profinet, and UDP/IP, facilitating the connection with user DCS system and realization of device centralized management.
11. IoT cloud program
- Support INVT optional IOT module with 2G/4G/4G SIM card , to connect into INVT Cloud data center, for remote in time running status monitoring. Save trouble shooting time and cost, more efficiency and intelligent
