13. USING A LINEAR SERVO MOTOR
13 - 67
Alarm No.27 Name: Initial magnetic pole detection error Stop method: Corresponding axis stops
Alarm description Initial magnetic pole detection cannot be performed properly.
Display Name Cause Checkpoint Finding Action
27.3 magnetic pole
detection limit
switch error
(1) Both of the magnetic pole
detection limit switches
are OFF.
Check that the limit
switches are ON. Limit switches are
OFF. Turn the limit switches
ON.
27.4 magnetic pole
detection
estimated error
(1) The estimated value
obtained from the
magnetic pole detection
is faulty.
Examine checkpoints described in the alarm display "27.1".
27.5 magnetic pole
detection position
deviation error
(1) Position deviation
increases during the
magnetic pole detection.
Examine checkpoints described in the alarm display "27.1".
27.6 magnetic pole
detection speed
deviation error
(1) Speed deviation
increases during the
magnetic pole detection.
Examine checkpoints described in the alarm display "27.1".
27.7 magnetic pole
detection current
error
(1) The current reaches the
alarm level during the
magnetic pole detection.
Examine checkpoints described in the alarm display "27.1".
Alarm No.28 Name: Linear encoder error 2 Stop method: Corresponding axis stops
Alarm description Fault is found in the surrounding environment of the linear encoder.
Display Name Cause Checkpoint Finding Action
28.1 Linear encoder
environment error
(1) Temperature of the linear
encoder is high.
Check the temperature of
the linear encoder. Temperature is high. Consult the linear
encoder manufacturer.
Temperature is low. Check (2).
(2) Signal level from the
linear encoder drops.
Check the installation of
the linear encoder. Problem found. Modify the installation
of the linear encoder.
Alarm No.2A Name: Linear encoder error 1 Stop method: Corresponding axis stops
Alarm description Error signal from the linear encoder is received.
Display Name Cause Checkpoint Finding Action
2A.1 Linear encoder
side error 1
(1) Not reproduced. Use in the adjusted
positions. Installation positions of
the linear encoder and
the head are faulty. Adjust the positions of the
linear encoder and the
head, and check the
reproducibility of the error.
Reproduced. Check (2).
(2) Fault is generated from
the surrounding
environment.
Check for noise and other
factors. Problem found. Take countermeasure
according to the
cause.
No problem found. Check (3).
(3) Alarm of the linear
encoder.
Check the details of
section 13.7.4. Improve the detail
information No.1 of
the linear encoder
manufacturer. Consult the linear
encoder
manufacturer.
