PLC status
5.2 ERROR MESSAGES
If the barfeeder evaluates certain situation as
an error status, an error message is displayed
on the control panel.
Cancel the error by the key
.
PLC status
In certain cases error messages contain PLC
status (xxx-xxx-xxx). This number states the
barfeeder's PLC status at the moment of error
occurrence. Knowledge of these values can significantly help in solving your eventual
problem. In error consulting the manufacturer may ask the status value.
Error Cause Corrective Action
1
Emergency stop Safety relay K1 is not closed. Check all E-stop buttons on both the lathe
and barfeeder. Ensure that no E-stop is on
the lathe. Close the barfeeder cover and
switch S3 key to MAN and press S10
button.
2
Wrong zero position Barfeeder detected a reference
point offset higher by more than
±
0.5 mm from usual value (distance
from the switch B33).
Remove dirt, which causes that the flag
cannot move the pusher to the back limit
position, from the pusher.
If the error repeats frequently, check the
mounting of the switch B33 and gears of
the motor M1. Fix the flag in the rear
position and try to turn the plastic toothed
wheel by hand in both directions. The
wheel must not turn with regard to the fixed
flag. The teeth clearance between the
pinion and the wheel has not effect on this
error.
3
Lathe isn't in AUTO If the barfeeder works in automatic
mode (it feeds, replaces or
measures the length of the bar on
the basis of EOB M-code), the lathe
must be in automatic mode. Ensure that the lathe is continuously in the
automatic mode in course of feeding,
replacement and measurement of the
length of the bar. Depending on interface
this signal is often replaced by the signal
from the door of the lathe workspace.
4
Collet is closed Clamping device closed unawares
in course of bar feeding or
replacement. Ensure that the clamping device is open in
course of bar replacement.
Clamping device must also be open for the
whole duration of M-code in course of
feeding.
5
Pusher before collet The pusher moved in course of
feeding before the clamping device
of the lathe. Check the setting of parameters #100 and
#102, or #105, #106 and #107 at feeding to
position.
6 (CE)
Magazine isn't closed
If the Barfeeder runs in the
automatic mode, the magazine
cover must be closed. Replenish the material in accordance with
Chapter 4.9.6.6.
Check the function of SQ32 switch.
7
Magazine is empty The magazine is empty. Replenish the magazine and renew the
automatic operation.
8
Collet is open In course of measurement of the
length of the bar clamped in the
lathe the clamping device opened.
Risk of uncontrollable extension of
the bar into the lathe workspace. Ensure that the clamping device is closed
during the measurement of the length of
the bar after the automat start and in
course of EOB M-code duration.
