Undervoltage (only with turret unlocked)
1
The power supply voltage on the M1
connector is less than selected voltage
- Check with a multimeter the voltage on the L1-L2-
L3 connector. If the alarm occurs during the
rotation the reason could be that the power supply
is not powerful enough
2.0
Power Error
2
-High Current peak.
-Input voltage over the range.
-Due to excessive regeneration during
breaking the bus voltage has risen (collision)
-Motor or Resolver problem
- Check with a multimeter the voltage on the L1L2-
L3 connector (230V +10% / 400V +10%).
- Check that the inertia and unbalancing applied to
the turret does not exceed the stated limits and
also the profile selected with the dipswitch is
appropriate to the load condition.
-or other problems contact our service
-Check motor resistence (instruction in the alaerm
8.0)
-Check the resolver resistence (instruction in the
alaerm 8.0)

During unlocking the turret stays closed [Li.12=Off, Li.13=On]
4
After 30” from the unlocking command
(Lo.15) there isn’t the signal from the
unlock proximity switch (Li.12) and the
turret remains closed (Li.13 = On)
Check the functionality of proximity switch.
- Check the hydraulic/pneumatic circuit.
- Check the electro valve/auxiliary relays
connection
4.1
No signal from unlock proximity switch [Li.12=Off, Li.13=Off]
10
After 30” from the unlocking command
(Lo.15) there isn’t the signal from the
unlock proximity switch (Li.12) and the
lock proximity switch is Off (Li.13)
- Check the functionality of proximity switch.
Remove the upper cover and verify that the
movement of the pin is not hindered.
- Check the hydraulic/pneumatic circuit. If present
- Check the live tool disengaging and the live tool
disengaged signal functionality
4.2
Lock proximity switch in short circuit [Li.12, Li.13=On]
11
During unlocking sequence, the lock
proximity switch remains On (Li.13)
- Check the functionality of lock proximity switch
4.3
The unlock proximity switch signal has been lost during rotation [Li.12=Off]
12
During the rotation the unlock proximity
switch(Li.12) is lost
- Check the functionality of unlock proximity switch
- Check the connection on turret pin 12 (both side
client and turret) and on M4 connector
