In the rmctool help refer to:
These steps come before actually tuning the gains.
- Test Wiring and Polarity
- Check the Deadband
- Non-linear Valves
- Adjust the Output Bias
- Set Up the Tuning Tools
- Set Symmetrical/Ratioed
I want to know what to pay attention to in addition to these.
1: the frequency curve of the speed and the voltage.
Is the speed curve a hysteresis voltage curve, a good hydraulic system, is there a requirement for this?
2: the consideration of linearity
0~8V voltage and speed have a better linearity. When more than 8V, the linearity is not good, although there is an increase, but the increase is not much.
1V—100mm/s 2v— 200mm/s 8V – 800mm/s 10V–820mm/s
How should we consider the voltage range of 8-10V?
