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
Position deviation setting value, [AL. 42 Servo control error] will occur.
error detection level However, when "0" is set, the level varies depending on the operation mode in [Pr. PA01].
Linear servo motor: 50 mm
Direct drive motor: 0.09 rev
Setting range: 0 to 1000

PL06 Set a speed deviation error detection level of the servo control error detection.
LB2 When the deviation between a model feedback speed and actual feedback speed is larger than the setting
Speed deviation value, [AL. 42 Servo control error] will occur.
error detection level However, when "0" is set, the level varies depending on the operation mode in [Pr. PA01].
Linear servo motor: 1000 mm/s
