Setting of response performance and load to motor mass ratio by minute position
detection method
When using the minute position detection method, set the response performance with [Pr. PL17.0 Response selection], the
load to motor mass ratio with [Pr. PL17.1 Load to motor mass ratio/load to motor inertia ratio]. If the load to mass of the linear
servo motor primary-side ratio is unknown, perform the magnetic pole detection by the position detection method, and then
perform the auto tuning to set an estimated value.

Setting of identification signal amplitude by minute position detection method
If [AL. 032 Overcurrent], [AL. 050 Overload 1], [AL. 051 Overload 2], or [AL. 0E1 Overload warning 1] occurs at the magnetic
pole detection by the minute position detection method, set a smaller value for [Pr. PL18 Magnetic pole detection - Minute
position detection method - Identification signal amplitude]. Basically, [Pr. PL18] does not need to be changed from the initial
value.
