PL05 Set a position deviation error detection level of the servo control error detection.
LB1 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.
Position
deviation However, when "0" is set, the level varies depending on the operation mode in
error [Pr. PA01].
