encoder and the
resolution setting of the
parameter are different.
Review the parameter
No.PS02 and PS03
settings.
Setting is correct.
Check (5).
(5)
The polarity is
incorrect.
Correct the setting.

encoder is incorrect.
(Installation direction is
incorrect.)
Check polarities of the
linear encoder and the
linear servo motor.
Normal. Check
(6).
(6) Initial magnetic pole
detection is not performed.
Not reproduced.
Perform the magnetic
pole detection.
Perform the magnetic
pole detection again, and
check the reproducibility
of the error.
Reproduced. Check
(7).
(7) Linear encoder is faulty.
Not reproduced.
Replace the servo
motor.
Replace the servo motor,
and check the
reproducibility of the error. Reproduced. Check
(8).
(8)

(9) Torque is saturated.
Check the torque during
the operation.
Torque is saturated.
Review the operation
pattern.
Torque is not
saturated.
Check (10).
(10) Servo amplifier is faulty.
Replace the servo
amplifier, and check the
reproducibility of the error.
Not reproduced.
Replace the servo
amplifier.
