4.6 Auto tuning mode
【
Pr.PA08
】
The driver has a built-in real-time auto-tuning function that estimates the machine characteristics (load
inertia moment ratio) in real time and automatically sets the optimum gain according to that value. This
function facilitates gain adjustment of the driver.
The parameters that are automatically adjusted differ depending on the gain adjustment mode.
The driver is set to "auto tuning mode 1" as shipped.
If you cannot obtain satisfactory adjustment, set the driver to "auto tuning mode 2" and then to "manual
mode".
For details, refer to "LECSN-T Operation Manual, Chapter 6”.

If LSP (forward stroke end) and LSN (reverse stroke end) detection is not performed by an external input
signal, set the input signal to "1: Automation on”.
If LSP and LSN are not detected, an alarm occurs.
Convert the setting value into hexadecimal as follows.
