3.1.3.5.5.1 Tuning the gains for method 1
The gains for PID tuning can be found in object 0x2009 :
Subitem 0x2009:4 defines K for method 1.
Subitem 0x2009:5 defines K for method 1.
Subitem 0x2009:6 defines K for method 1.
Note
As a rule of thumb, the following approach can be applied:
Start values of the gains:
K = 1
K = 1
K = 0
Increasing and decreasing K and K will have the same effect as increasing them in a simple PID
position controller.
If needed, the increase in K should be done in very small steps (such as changing from 0 to 0.001), this
will reduce the oscillations of the load.
