1. TROUBLESHOOTING FOR SERVO AMPLIFIER (DRIVE UNIT)
1 - 53
Alarm No.: 42 Name: Servo control error (for linear servo motor and direct drive motor)
Alarm content A servo control error occurred.
Detail
No.
Detail name Cause Check method Check result Action Target
42.3 Servo control
error by torque/
thrust deviation
(1) The linear encoder
resolution setting differs
from the setting value.
Check the setting of
[Pr. PL02] and [Pr.
PL03]. The setting is
incorrect. Set it correctly. [A]
[B]
[WB]
[GF]
The setting is
correct. Check (2).
(2) The direction of
mounting linear encoder
is incorrect.
Check polarities of
the linear encoder
and the linear servo
motor. The mounting
direction is incorrect. Mount it correctly.
Review the "encoder
pulse count polarity
selection" setting of
the parameter as
required.
[A]: [Pr. PC45]
[B] [WB] [GF]:
[Pr. PC27]
The mounting
direction is correct.
Check (3).
(3) The connection of the
servo motor is incorrect.
Check the wiring. The wiring is
incorrect. Connect it correctly.
The wiring is correct. Check (4).
(4) The initial magnetic pole
detection was not
executed.
Execute the magnetic
pole detection, and
then check the
repeatability. It is not repeatable. Execute the
magnetic pole
detection.
It is repeatable. Check (5).
(5) The torque/thrust
deviation exceeded the
detection level.
Calculate the deviation
between the current
command and
torque/thrust. The deviation is
large. Review the operation
status. Review the
[Pr. PL07] setting
depending on
circumstances.
Alarm No.: 42 Name: Fully closed loop control error detection (during fully closed loop control)
Alarm content A fully closed loop control error has occurred.
Detail
No.
Detail name Cause Check method Check result Action Target
42.8 Fully closed
loop control
error by position
deviation
(1) The resolution of the
load-side encoder
setting differs from the
setting value.
Check the setting of
[Pr. PE04] and [Pr.
PE05]. The setting is
incorrect. Set it correctly. [A]
[B]
[WB]
[GF]
The setting is
correct. Check (2).
(2) The direction of
mounting load-side
encoder is incorrect.
Check the mounting
direction of the load-
side encoder. The mounting
direction is incorrect. Mount it correctly.
Review the "encoder
pulse count polarity
selection" setting of
the parameter as
required.
[A]: [Pr. PC45]
[B] [WB] [GF]:
[Pr. PC27]
The mounting
direction is correct.
Check (3).
(3) The position deviation
exceeded the detection
level.
Check the value of
droop pulses. The deviation is
large. Review the operation
status. Review the
[Pr. PE07] setting
depending on
circumstances.
