PL05
LB1
Position deviation
error 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].
Linear servo motor: 50 mm
Direct drive motor: 0.09 rev
Setting range: 0 to 1000 0 [mm]/
[0.01 rev]
PL06
LB2
Speed deviation
error detection 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].
Linear servo motor: 1000 mm/s
Direct drive motor: 100 r/min
Setting range: 0 to 5000 0 [mm/s]/
[r/min]
PL07
LB3
Torque/thrust
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.
Setting range: 0 to 1000 100 [%]
