[AL. 042_Servo control error]

• A servo control error occurred.
[AL. 042.1_Servo control error by position deviation]
Cause
1.
The setting of the encoder resolution differs
from the actual value.
2.
The mounting direction of the encoder is
incorrect.
3.
The connection of the servo motor is incorrect.
4.
The initial magnetic pole detection was not
executed.
5.
The setting value is low in the position
deviation error detection level.
[AL. 042.2_Servo control error by speed deviation]
Cause
1.
The setting of the encoder resolution differs
from the actual value.
2.
The mounting direction of the encoder is
incorrect.
3.
The connection of the servo motor is incorrect.
4.
The initial magnetic pole detection was not
executed.
5.
The setting value in the speed deviation error
detection level is low.
Check/action method
Check the setting of [Pr. PL02 Linear encoder resolution setting - Numerator]
and [Pr. PL03 Linear encoder resolution setting - Denominator].
Refer to "Linear encoder resolution setting" in the following manual.
MR-J5 User's Manual (Hardware)
Check the polarities of the linear encoder and the linear servo motor.
If the mounting direction is incorrect, mount the encoder correctly.
Change the setting of "Encoder pulse count polarity selection" as required.
