Perfect Power Output Section
The HIVERT general MV VFD adopts the power cells connected in series and voltage overlapping method (i.e. Power cells multi-level cascade technology), it can output the perfect PWM sinusoidal waveform (see Figure 2 and Figure 3). It has the following advantages:
1. No need for the additional output filter
2. Directly driving general synchronous or asynchronous motor
3. No de-rating operation on the motor
4. No dV/dt stress on the insulation of motor and cables
5. No torque ripple, extending service life of motors and mechanism
6. No cable length restriction within the acceptable voltage drop.
Front access design for easy maintenance of power modules that can be replaced in just a few minutes.
∙ Single power cell design for all modules allows reduced spare parts inventory cost.
∙ 2-Quadrant and 4-Quadrant versions available.
∙ Fibre-optic interface for safe control and feedback communication with controller.
Door-mounted easy-to-use 7-inch color LCD touch-screen Main panel
∙ User-friendly interface with operational data at your fingertips
∙ Virtual meters display main VFD parameters
∙ System and status monitoring and manual controls
∙ Power module status monitoring
∙ Data logging, trending displays, diagnostic information available
∙ Multiple languages available
∙ Parameter adjustment and operation records
∙ Dedicated multi-level menu to guide user with different access levels for service and commissioning engineers (Operator, Manager and Administrator)
