OKE inverters employ precise sensorless vector control technology and professional torque control technology, featuring fast response speed, accurate self-learning of stator, rotor, resistance, inductance, mutual inductance and other parameters, and excellent performance. They can intelligently tune to the optimal control mode.
OKE inverters have two self-learning modes: a comprehensive parameter self-learning mode and a static parameter self-learning mode. Both modes can only be used without PG vector control. Setting P03.11 to 1 enables comprehensive self-learning, and setting P03.11 to 2 enables static self-learning.
When using the intelligent self-learning function for motor parameters on an OK inverter, it is essential to disconnect the motor from the load and ensure that there is no danger even if the motor is rotating before implementing full self-learning. OK inverters automatically measure motor parameters during self-learning, which is fundamentally different from the self-learning of servo systems (measuring the load size). To achieve speed accuracy at high speeds (above 90% of rated speed), select a motor with a rated voltage at least 20V lower than the inverter's input power supply rating. If the input power supply voltage is the same as the motor's rated voltage, the inverter's output voltage will be insufficient, and speed accuracy will not be achieved.
