Set the parameters in the window below:
Note:
You can set the ratio of machine load moment of inertia (p29022) with the following
methods:
• Enter it manually if you have known the ratio of machine load moment of inertia
• Use the ratio of machine load moment of inertia estimated by the one-button auto
tuning function directly
• Estimate the ratio of machine load moment of inertia with real-time auto tuning
(p29024.2 = 1). When you have obtained a stable value of p29022, you can stop
estimating it by setting p29024.2 = 0.
Parameter p29028 is available when the multi-axis interpolation function is activated
(p29024.7 = 1). If the axes are used as the interpolation axes, you need to set the same
pre-control time constants (p29028) for them. After tuning is completed, you need to
manually set the same position loop gains (p29110 [0]) for them if the tuning results are
different.
The parameters in advanced settings window must be set carefully when the auto-tuning
function is disabled (p29021 = 0).
Click the following button to start tuning after the parameters are set.
