Brand-new dimensional vector techniqueThe excellent vector calculation guarantees the large torque of low frequency provided that the switch loss is the least. With highly efficient utilization of the network and voltage and optimized sine wave output, the motor operation noise is lowered and heat reduced.Unique software dead area compensationThe dead-area time is the critical reason for the low frequency impulse torque of the frequency conversion devices. The unique software dead-area compensation of RNB3000 further guarantees the stable torque under low frequency and extreme speed.Excellent tracking self-start of non-speed sensor with speed shiftFor the stop running of the inverter caused by various reasons, and the trouble is removed before the motor stops running, RNB3000 can automatically detects the motor speed and stably tracks the rotary speed.Automatic energy saving operationWith the unique software power factor regulation, it dynamically regulates the power factor according to different load and saves more energy.Voltage fluctuation restrainDynamic automatic voltage control (AVC) ensures that when the input voltage fluctuation is ±30%, the output voltage fluctuation is less than ±5%.Complete protectionIt has protection to over voltage, over current, under voltage, JGBT short circuit, anti- time limit overload and so on. Besides, it provides safe protection under short circuit load or grounding.DC power supplySave the investment for safe power supply.Preset flexible PWM energy loss brakeUsers may choose suitable brake resistors to provide energy loss brake.Friendly man-machine interface, flexible input and output interfaceLCD Chinese/English display, keyboard multi-machine parameter copy (optional).It provides 7 digital input routes, 2 analog input routes, 2 analog output routes and joints for 3 digital output routes
