Features

Feature 1: Three Control modes

1. High performance V/F control. (Fans, Pumps, Air compressors, etc).
2. Open loop vector control. (Belt conveyer, mill drive, fibrizer crusher, etc.)
3. Close loop vector. (Applicable to internal mixer, hoister machine, etc.)

Feature 2: Multiple types of motor drives

• Support Asynchronous motors
• Synchronous motors (Include PM synchronous motors)

Feature 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 off 0-5s.

Feature 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.

Feature 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.

Feature 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

Feature 7: Excellent Low Frequency Control

• Advanced dead area compensation technology, good low frequency waveforms; Optimized algorithm of low frequency oscillation suppression, no motor resonance

Feature 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.

Feature 9: Heat Dispersion Simulation

• With advanced heat simulation technology, high reliable structure design for heat dispersion.
