The drive holds three gain buffers, any buffer can be selected for use by the speed controller with parameter 3.16.
0 = Terminal input control
1 = PID buffer 1 is selected
2 = PID buffer 2 is selected
3 = PID buffer 3 is selected
Summary of effected parameters when switching P.I.D buffers
Total inertia driven by the motor is the sum of: Load Inertia + Motor Inertia.
This is required to calculate the PID gains.
The stiffness angle is the required angular displacement when the drive delivers a torque producing current equivalent to the drive rated
