12. DRIVE ALARM
When malfunctioning occurs:
- are disabled the outputs ST INDEX, ST LOCK and POSITION FEEDBACK
- the display shows the active alarm
- are activated the alarm bit in the J1 connector (binary coded)
Display Description Code

3.4 (A5.1) Radiator thermal alarm
3.6 (A6.0) Radiator thermal alarm
3.e (A14.0) Motor phases swapped or not connected
Turret Unlocking Alarm
4.0 During unlocking the turret stays closed [Li.12=Off, Li.13=On] 4
4.1 No signal from unlock proximity switch [Li.12=Off, Li.13=Off] 10
4.2 Lock proximity switch in short circuit [Li.12, Li.13=On] 11
4.3 The unlock proximity switch signal has been lost during rotation [Li.12=Off] 12
Turret Unlocking Alarm
5.0 During locking the turret stays unlocked [Li.12=On, Li.13=Off] 5
5.1 No signal from lock proximity switch [Li.12=Off, Li.13=Off] 16
5.2 Unlock proximity switch in short circuit [Li.12, Li.13=On] 17
5.3 The lock Px switch signal has been lost during work (turret indexed) [Li.13=Off] 18
5.7 Turret not locked at the start up [Li.13=Off] 30
Turret Positioning Alarm
6.2 Zero search error 22
6.3 Positioning error 23
7.0 No signal from Zero proximity switch 7
7.1 Zero proximity switch in short circuit 25
7.2 Time out rotation (60”) 26
Resolver Alarm
8.0 Resolver malfunctioning 8
8.1 Motor PTC 13
Positioning Alarm
9.0 Parity error 9
9.1 A non-existing position has been called 28
9.2 Zero search in operative mode different from 1 29
In the table the CODE field is the
sum of all bits of alarm active.
Example: All.7.0 Time out
rotation
Code 7, on connector J1 will be
activated the output: Lo.6 (1),
Lo.7 (2), Lo.8 (4) = 1 +2 +4 = 7
