10 USING A LINEAR SERVO MOTOR
10.3 Startup [A]
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.
• [Pr. PL17.0 Response selection]
Initial value: 0
• [Pr. PL17.1 Load to motor mass ratio/load to motor inertia ratio selection]
Initial value: 0
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.
