Torque Increase Automatic torque increase: manual torque increase 0.1%~30.0%
Acceleration and deceleration curves Linear or S-curve acceleration and deceleration modes. 3 types of acceleration and deceleration times, acceleration and deceleration times range from 0.0 to 600.0s.
Multi-band speed operation Up to 8-band frequency setting through the control terminal.
AVR (Automatic Voltage Regulation) The output voltage can be automatically kept constant when the grid voltage changes.
Over-voltage and over-voltage speed control White-action limitation of current and voltage during operation prevents frequent over-current and over-voltage tripping.
Fast current limiting function minimises overcurrent faults and protects the normal operation of the frequency converter.
Torque limitation and control Automatic limitation of torque during operation to prevent frequent overcurrent tripping: closed-loop quantitative torque control can be realised.

FAQ
How Many Types of Frequency Converters Are There?
Inverters can be divided into low-voltage inverters and high-voltage inverters according to input voltage levels. Common low-voltage inverters in China include single-phase inverters and three-phase inverters. High-voltage frequency converters commonly include 6kV and 10kV transformers, and the control method is generally converted according to high-low-high-frequency conversion or high-high-frequency conversion.
Low voltage frequency converter
Suitable for low-voltage motors, usually operating voltage below 690V.
Widely used in industrial and commercial fields.
High voltage frequency converter
Suitable for high-voltage motors, the working voltage is usually above 690V, even reaching several thousand volts.
Used in large industrial equipment and power transmission systems.
