Time out rotation
25
After to call a zero research (hidden too)
Zero proximity switch (Li.14) is always Off
Turret has not reached called position
- Check the functionality of zero proximity switch
- Check the calibration of zero cam
- 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)

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

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
