EXTENDED ALARM DESCRIPTION/TROUBLESHOOTING
ALARM
CODE
Description
10
Fault in internal supply: check the 230 V auxiliary supply.
11
Drop on the Three-Phase voltage during tool change. Check the Three-Phase voltage. (only SW rel I)
20
Overvoltage:
- Check all external three-phase supplies.
21
Overvoltage reached during dynamic braking:
-the inertia loaded on disc is too high: check that the configuration signal (PTAB03 -LK3 on connection board) is
set to the proper inertia range.
-Check that the Three-Phase voltage is not over specs.
30
Motor Overload (mean current too high):
-the indexing frequency is too high.
31
Overcurrent (current limit reached):
-inertia loaded on disc exceeds limits (check that the turret is set to the right inertia value by the PTAB03 signal
– LK3 on connection box);
-the unbalanced load exceeds limits;
-crash during disc rotation;
-zero switch or zero cam are not well positioned (if the alarm happen when the turret is locking at the reference
cycle completion;
-wiring to the motor or the resolver is defective.
32
Following error:
-inertia loaded on disc exceeds limits (check that the turret is set to the right inertia value by the PTAB03 signal
– LK3 on connection box);
-the unbalanced load exceeds limits;
-the tool touch the piece slowly during disc rotation;
-the wiring to the resolver is defective.
33
The time limit to execute the cycle has been reached:
-the tool touch the piece slowly at the end of the cycle so cannot reach the final position;
35
The thermal detector of the motor :
-indexing frequency too high;
-defective motor;
-the thermal detector is not connected.
36
The reference cam is not in the expected position. (only SW rel I)
40
The signal of the locking switch stays on during the unlocking phase:
-unlocking pressure too low;
-bad position of locking switch;
-bad switch connection/wiring (remote application mainly);
-the locking switch is defective.
41
The signal of the unlocking switch stays off during the unlocking phase:
-unlocking pressure too low;
-bad position of locking switch;
-bad switch connection/wiring (remote application mainly);
-the locking switch is defective.
42
The signal of the unlocking switch goes off while the turret is unlocked:
-problems of pressure;
-bad switch connection/wiring (remote application mainly);
-the unlocking switch is defective.
43
The signal of the locking switch goes on while the turret is unlocked:
-problems of pressure;
-bad switch connection/wiring (remote application mainly);
-the locking switch is defective.
44
The turret is unlocked at power-on:
-the electrovalve is defective or positioned in such a way that the internal part can move without command
(vertical);
45
The two pressure inlet or the LOCKED and UNLOCKED switches are reversed. (only SW rel I)
