Real-time identification
The setting of real-time identification refers to the Inertia Ratio of the real-time identification system. The real-time
identification level can be set according to the speed of load characteristics changes. Relevant parameters are as follows:

Byte0: Real time identification selection
0x00-Disable;
0x01-Enable.
Byte1: Real time identification level selection
0x00-The load characteristics are almost constant;
0x01-The load characteristics change slowly, in minutes;
0x02-The load characteristics change quickly, in seconds;
0x03-The load characteristics change rapidly, in milliseconds.
The real-time identification level is effective only when real-time identification is enabled.

Real-time identification can be inaccurate in the following situations:
The load inertia ratio is more than 10
Motor speed is constantly lower than 1% of the rated speed
Acceleration and deceleration are lower than the minimum identified acceleration: the speed
changes by rated speed within 1s.
The mechanical rigidity is very low
The drive mechanism has nonlinear characteristics because of gaps
Real-time automatic adjustment
Real-time automatic adjustment means that the parameter [
Inertia Ratio Setting] (0x20C0) can be updated following the
real-time identification of the load inertia ratio. It is suitable for complicated mechanical structures where the rotary inertia
ratio is not constant. By using this function, the precise value of rotary inertia ratio can be obtained in real time.
