What is the cause of the AL50 fault alarm in the NC feeder? In
fact, the alarm is an overload alarm. After analysis, there are
several situations. Ruihui Machinery explains the customer
maintenance and repair:
1, electrical aspects: servo motor or drive failure, the reasons
are
(1) When the NC feeder is reinstalled, the drive or motor is subjected to illicit
collision;
(2) The servo motor is loose inside due to vibration of the NC
feeding electromechanical box. The detection method of the problem:
after the servo failure, it is necessary to power off after a
period of power-off, and then manually control the feeder to enter
and retreat.
If no alarm occurs, the possibility can be eliminated; if such a
situation occurs, the servo system has to be replaced, the process
is troublesome, and the probability of occurrence of the fault is
small, rarely occurs, and can be ignored.
2, mechanical aspects:
(1) The NC feeder's rolling bearing is stuck and causes an alarm.
The detection method is: servo off, and then manually rotate the
feeding roller under no-load conditions. If there is obvious jam or
unsmooth phenomenon, it means the bearing is faulty. The failure
rate is also relatively low, generally does not appear, if it
occurs, the bearing must be replaced.
(2) After the customer replaces the mold, the height of the lower
mold is inconsistent with the height of the last mold or the length
of the positioning pin is inconsistent, which causes the relaxation
time to be delayed, causing the positioning pin to stretch the
material and alarming. This probability is large.
The detection method is: manual control of the slow decline of the
punch, careful observation of the drum relaxation time, repeated
detection, that is, the problem can be found. Solution: Adjust the
relaxation time; reduce the NCF feed height to be flush with the
mold or about 3mm lower.
(3) If the material is replaced, the thicker material is used, and
then the limit block is added in front, which may also cause an
alarm phenomenon. The probability is small and it is not easy to
appear, and the customer can find it by himself.
