Speed deviation error detection
Set [Pr. PL04.0] to "2" to enable the speed deviation error detection.
When the difference between the model feedback speed ( 3)) and the feedback speed ( 4)) in the figure is equal to or more
than the value of [Pr. PL06 Speed deviation error detection level] (1 mm/s to 5000 mm/s), [AL. 042.2 Servo control error by
speed deviation] occurs and the linear servo motor stops. The initial value of this detection level is 1000 mm/s. Change the
setting value as necessary.
■
Thrust deviation error detection
Set [Pr. PL04.0] to "4" to enable the thrust deviation error detection.
When the difference between the command thrust ( 5)) and the feedback thrust ( 6)) in the figure is equal to or more than the
value of [Pr. PL07 Torque/thrust deviation error detection level] (1 % to 1000 %), [AL. 042.3 Servo control error by torque/
thrust deviation] occurs and the linear servo motor stops. The initial value of this detection level is 100 %. Change the setting
value as necessary.
■
Detecting multiple deviation errors
When [Pr. PL04.0 [AL. 042 Servo control error] detection function selection] is set as follows, multiple deviation errors can be
detected. For the error detection method, refer to the following.

Linear servo control error controller reset condition selection
Select the reset condition of the linear servo control error.
When [Pr. PL04.3 [AL. 042 Servo control error] detection controller reset condition selection] is set to "1" (Reset enabled), [AL.
042.1 Servo control error by position deviation], [AL. 042.2 Servo control error by speed deviation], and [AL. 042.3 Servo
control error by torque/thrust deviation] can be canceled by resetting the controller. When [Pr. PL04.3] is "0" (Reset disabled
(reset by powering off/on or software reset enabled)), [AL. 042.1], [AL. 042.2], and [AL. 042.3] can be canceled only by cycling
the servo amplifier power or resetting the software.
