14. USING A LINEAR SERVO MOTOR

14 - 24

(a) Position deviation error detection

Set [Pr. PL04] to "_ _ _ 1" to enable the position deviation error detection.

When you compare the model feedback position ( 1)) and the feedback position ( 2)) in figure 14.1, if

the deviation is more than the value of [Pr. PL05 Position deviation error detection level] (1 mm to

1000 mm), [AL. 42.1 Servo control error by position deviation] will occur and the linear servo motor

will stop. The initial value of this detection level is 50 mm. Replace the set value as required.

(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 14.1, if

the deviation is more than the value of [Pr. PL06 Speed deviation error detection level] (1 mm/s to

5000 mm/s), [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 1000 mm/s. Replace the set value as required.

Set [Pr. PL04] to "_ _ _ 4" to enable the thrust deviation error detection.

When you compare the command thrust ( 5)) and the feedback thrust ( 6)) in figure 14.1, 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.
