Special functions Self-voltage stabilization function (AVR) Automatically stabilizes the output voltage when the supply voltage fluctuates abnormally.
Power saving function The function automatically saves electricity when the engine is overloaded
Increase engine power factor.
Functions dedicated to the yarn and textile industry The cycling speed control changes to the reel.
Function timer, counter Integrated timer and counter timer to suit different applications ..
Load balancing function When multiple motors are pulling the same load, this function helps balance the distributed load across the motors by reducing the speed down based on the increased value of the load.
Moment compensation function Increases the torque characteristic of V / F control when the motor works at low speed.
Control function brake Brakes kinetic energy, wins on excitation, wins DC
Functions help the system to operate continuously Automatically reset the error according to preset times and times
Maintains operation during transient power outages and wide operating voltage range suitable for flickering power locations.
Load balancing function When multiple motors are pulling the same load, this function helps balance the distributed load across the motors by reducing the speed down based on the increased value of the load.
Function of inspection and supervision Connect a computer to monitor the operation as well as set parameters for the inverter thanks to software INVT studio V1.0, HCM.
