(b) Speed deviation error detection
Set [Pr. PL04] to "_ _ _ 2" to enable the speed deviation error detection.

When you compare the model feedback speed ( 3)) and the feedback speed ( 4)) in figure 15.1, if
the deviation is more than the value of [Pr. PL06 Speed deviation error detection level] (1 r/min to
2000 r/min), [AL. 42.2 Servo control error by speed deviation] will occur and the linear servo motor
will stop. The initial value of this detection level is 100 r/min. Replace the set value as required.
(c) Torque deviation error detection level
Set [Pr. PL04] to "_ _ _ 4" to enable the torque deviation error detection.

When you compare the command torque ( 5)) and the feedback torque ( 6)) in figure 15.1, if the
deviation is more than the value of [Pr. PL07 Torque/thrust deviation error detection level] (1% to
1000%), [AL. 42.3 Servo control error by torque/thrust deviation] will occur and the linear servo
motor will stop. The initial value of this detection level is 100%. Replace the set value as required.
(d) Detecting multiple deviation errors
When setting [Pr. PL04] as shown below, multiple deviation errors can be detected. For the error
detection methods, refer to (1) (a), (b), (c) of this section.
