VFD: Features

Stable and reliable performance
Saves energy and therefore reduces energy costs
Isolated control signal provided by fibre optics between Power cell and Controller
Voltage resource VFD, direct input of 3, 3.3, 4.16, 6, 6.6 and 10 kV, direct output of 3, 4.16, 6, 6.6 and 10 kV, no output transformer necessary. High input power factor, low harmonic current, no power factor correction capacitors and harmonic filters required.
Sinusoidal multi-level PWM output waveform, no output filter required. Can be directly connected to standard induction motor, without damage to the insulation of the cable or the motor, low harmonics of the motor, reduction of vibration of the shafts or the vanes. Maximum length of output cable 1000 m.
Modular design of the power circuits for simpler maintenance routines.
Complete fault monitor circuit for accurate fault alarm and protection.
Integrated cooling.
The control logic can be easily changed with the help of the integrated PLC
Support for standard industrial communication protocols (Modbus, Profibus, DeviceNet, TCP/ IP etc.)
Analog input 0 ~ 10V / 4 ~ 20 mA for frequency setting.
Open or closed loop control with the integrated PID regulator.
Complete system setup via parameter settings
Easy installation
The VFD can self-diagnose and record faults. For trips, an alarm message is displayed in main
interface; for serious trips, the trip window and the fault location is automatically displayed. The
trip log can be viewed from the trip window.
