15. USING A LINEAR SERVO MOTOR

(3) Program operation
Positioning operation can be performed in two or more operation patterns combined, without using a
controller. Use this operation with the forced stop reset. This operation may be used independently of
whether servo-on, servo-off, or whether a controller is connected or not.
Exercise control on the program operation screen of MR Configurator2. For full information, refer to the
MR Configurator2 Installation Guide.

Forced stop Click the "Forced Stop" button.
15.3.5 Function
(1) Linear servo control error detection function
POINT
For the linear servo control error detection function, the position and speed
deviation error detections are enabled by default. ([Pr. PL04]: _ _ _ 3)
If the linear servo control gets unstable for some reasons, the linear servo motor may not operate
properly. To detect this state and to stop operation, the linear servo control error detection function is
used as a protective function.
The linear servo control error detection function has three different detection methods: the position
deviation, speed deviation, and thrust deviation. An error is detected when each method is enabled with
[Pr. PL04 Linear servo motor/DD motor function selection 2]. The detection level can be changed with
[Pr. PL05], [Pr. PL06], and [Pr. PL07].
