detection
level Set a 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 varies depending on the operation mode in
[Pr. PA01].

level Set a 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.
However, when "0" is set, the level varies depending on the operation mode in
[Pr. PA01].

deviation error
detection level Set a 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.
