7.1 Zero proximity switch in short circuit
25
The zero proximity (Li.14) is always On
Check the functionality of zero proximity switch
proximity
7.2 Time out rotation (60”)
26
Turret has not reached called position
within 60” from calling
- Make sure there are no mechanical interferences
that prevent the rotation of the turret.
- Check the wired connections between drive and
turret (M1 UVW and J2)
8.0 Resolver malfunctioning
8
This alarm is activated when the signal
from the resolver is low or absent.
Check wiring of connector J2 and connections in
the terminal block signals on the turret.
- Check the integrity and continuity of the cable.
- Check that the Drive is set to the motor in use

8.1 Motor PTC
13
This alarm is activated when is not
detected the continuity between pin 1 and 2
of J2. The temperature sensor (PTC) of the
motor indicates an excessive winding
temperature
- Make sure that the ambient temperature (near the
motor) is within the limits allowed.
- If the alarm persists even when the engine is cold,
check the wires connecting the sensor (pins 1 and 2
of J2 on board and the terminal turret)
9.0 Parity error
9
This alarm occurs before the turret is
unlocked when the START command is
sent and the parity bit is not set correctly
- Check the connection J1 pin 23 with the plc
- Ensure that the program plc correctly handles the
parity bit
- Check that there is a delay in the plc of at least
50ms
between the setting of the position and parity to
the
START command
9.1 A non-existing position has been called
28
Has been requested a position higher
than the number of station provided
- Check the setting of dipswitch.
- Check code management of the position in the
plc.
- Check wiring of connector J1.
- Check/Reset the drive setup (page n°10)
9.2 Zero search in operative mode different from 1
29
The alarm is activated after the START
command, before unlocking the turret when:
- Operation Mode ≥ 2
- Position code = 0
- Check code management of the position in the
plc.
- Check wiring of connector J1
