13. USING A LINEAR SERVO MOTOR
13 - 34
(b) Speed deviation error detection
Set the parameter No.PS04 to " 2" to make the speed deviation error detection enabled.

Parameter No.PS04
If there is a deviation larger than the setting value (1 to 5000mm/s) of the parameter No.PS06 (Linear
servo control speed deviation error detection level) after comparing the model feedback speed 3) and
the feedback speed 4) in Figure 13.1, the alarm (Linear servo control error 42. ) occurs, and the linear
servo motor stops. The factory setting of parameter No.PS06 is 1,000mm/s. Change the setting value
as necessary.
(c) Thrust deviation error detection
Set the parameter No.PS04 to " 4" to make the thrust deviation error detection enabled.

Parameter No.PS04
If there is a deviation larger than the setting value (1 to 1,000 ) of the parameter No.PS07 (Linear
servo control thrust deviation error detection level) after comparing the command thrust 5) and the
feedback thrust 6) in Figure 13.1, the alarm (Linear servo control error 42. ) occurs, and the linear
servo motor stops. The factory setting of parameter No.PS05 is 100 . Change the setting value as
necessary.
(d) Detecting multiple deviation errors
Setting the parameter No.PS04 as shown below allows the linear servo motor to detect multiple
deviation errors. For the error detection methods, refer to (1) (a), (b) and (c) in this section.
