PL05 LB1 Position deviation error detection level
This is used to set the position deviation error detection level of the servo control error
detection.
When the deviation between a model feedback position and actual feedback position is larger
than the setting value, [AL. 42 Servo control error] will occur.
However, when "0" is set, the level vary depending on the operation mode in [Pr. PA01].

This is used to set the speed deviation error detection level of the servo control error
detection.
When the deviation between a model feedback speed and actual feedback speed is larger
than the setting value, [AL. 42 Servo control error] will occur.

This is used to set the torque/thrust deviation error detection level of the servo control error
detection.
When the deviation between a current command and current feedback is larger than the
setting value, [AL. 42.3 Servo control error by torque/thrust deviation] will occur.

This digit will be enabled when "minute position detection method"
is selected in [Pr. PL08 (_ _ _ x)].
If a linear encoder whose resolution is smaller than 0.05 μm is used
and also [AL. 27 Initial magnetic pole detection error] occurs
because the travel distance at magnetic pole detection is too large
or vibration occurs, set "1" (enabled).
This digit is available on servo amplifiers with software version A8
or later.

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.

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.
