1. TROUBLESHOOTING FOR SERVO AMPLIFIER (DRIVE UNIT)
1 - 95
Alarm No.: 90 Name: Home position return incomplete warning
Alarm content A home position return did not complete normally with the positioning function.
Detail
No.
Detail name Cause Check method Check result Action Target
90.2 Home position
return
abnormal
termination
(1) The proximity dog is
not connected to DOG.
Check if the proximity
dog is connected
correctly. It is not connected. Connect it correctly. [A]
[GF]
It is connected. Check (2).
(2) The stroke limit was
detected after the
home position return
start.
Check if the stroke
limit is connected
correctly.
Or check if the stroke
limit is not reached. The stroke limit is
not connected.
Or the stroke limit is
reached. Connect the stroke
limit correctly.
Review the stroke
limit position.
The stroke limit is
connected.
Or the stroke limit is
not reached. Check (3).
(3) A home position return
speed did not
decelerate to a creep
speed.
Check if the proximity
dog turned off before a
home position return
completed
deceleration to a creep
speed. The proximity dog
turned off before the
deceleration to a
creep speed. Review the dog
position.
Or review the
parameter values of
the home position
return speed, creep
speed, and travel
distance after
proximity dog. [A]
[GF]
(4) Deceleration from the
home position return
speed/creep speed to
the home position
failed at the indexer
method.
Check if the home
position was turned
on before the
deceleration from the
home position return
speed/creep speed to
the home position
was complete. It was not turned on
before the
deceleration was
complete. Review the positional
relationship of the
stroke limit and
home position. Or
review the parameter
values of the home
position return
speed, creep speed,
deceleration time
constant, and home
position shift
distance.
90.5 Z-phase
unpassed
(1) The Z-phase signal was
not detected normally.
Check if the Z-phase
signal of the servo
motor/linear servo
motor was detected
normally. The Z-phase signal
was not detected. Review the Z-phase
signal and wirings. [A]
[GF]
The Z-phase signal
was detected. Check (2).
(2) A home position return
was executed while the
servo motor did not
pass the Z-phase.
Check if the motor
passed the Z-phase
signal until the
proximity dog turned
off after the home
position return started. The Z-phase was
not turned on. Review the setting
position of the home
position return start
and proximity dog.
Alarm No.: 91 Name: Servo amplifier overheat warning
Alarm content The temperature inside of the servo amplifier reached a warning level.
Detail
No.
Detail name Cause Check method Check result Action Target
91.1 Main circuit
device overheat
warning
(1) Ambient temperature of
the servo amplifier has
exceeded 55
˚ C.
Check the ambient
temperature. It is over 55 ˚ C. Lower the ambient
temperature. [A]
[B]
[WB]
[RJ010]
[GF]
It is less than 55 ˚ C. Check (2).
(2) The close mounting is
out of specifications.
Check the
specifications of close
mounting. It is out of
specifications. Use within the range
of specifications.
