5. PARAMETERS
No. Symbol
PL09 LPWM Magnetic pole detection voltage level
This is used to set a direct current exciting voltage level during the magnetic pole detection.
If [AL. 32 Overcurrent], [AL. 50 Overload 1], or [AL. 51 Overload 2] occurs during the magnetic
pole detection, decrease the setting value.
If [AL. 27 Initial magnetic pole detection error] occurs during the magnetic pole detection,
increase the setting value.
PL17 LTSTS Magnetic pole detection - Minute position detection method - Function selection
To enable the parameter, select "Minute position detection method (_ _ _ 4)" in [Pr. PL08].

Setting value
PL18 IDLV Magnetic pole detection - Minute position detection method - Identification signal amplitude
Set an identification signal amplitude used in the minute position detection method.
This parameter is enabled only when the magnetic pole detection is the minute position
detection method.
However, setting "0" will be 100% amplitude.
Name and function
Response selection
Set a response of the minute position detection method.
When reducing a travel distance at the magnetic pole detection,
increase the setting value. Refer to table 5.9 for settings.
Load to motor mass ratio/load to motor inertia ratio selection
Select a load to mass of the linear servo motor primary-side ratio or
load to mass of the direct drive motor inertia ratio used at the
minute position detection method. Set a closest value to the actual
load.
Refer to table 5.10 for settings.
