INDEXD SIGNAL
The INDEXD signal must be used with the LOCKED signal to detect the end of cycle of the turret and can be
ignored once the turret is locked.
The INDEXD output goes and stay LOW also when the emergency mode is set and if the three-phase power
supply is OFF.
In this case, if the turret management from PLC/CNC uses the emergency mode or open the power contactor,
the INDEXD signal must be used only when the turret is in cycle and then ignored.
The CNC/PLC program must check the LOCKED signal while the turret is not in cycle: if this signal goes LOW
stop immediately the machine and check the cause.
ALARM CONDITIONS
When an alarm condition is detected, one or more of the ALBIT1, ALBIT2, ALBIT4 is high and the INDEXD
signal is low.
When at least one of ALBITxx is HIGH, ALPOSxx outputs give the second digit of the alarm code.
In this case the machine must be immediately stopped and the three-phase power contactor should be
opened.
Important: the turret can show alarms in any time (also if it is not on cycle) so
check always the alarm output
of the turret.
JOG MODE
If the ALPOSxx outputs are not used, the CNC does knows the actual turret position based only on the memory
of the last position called. The Jog mode does not require to set the next position number but just ask the turret
to go in the next/previous one. Be sure to not show in the screen of CNC a tool position different from the
reality.
EXCESSIVE ELECTRICAL NOISE OR BAD WIRING DETECTION
If the turret is not in cycle and in automatic mode, any variation in POSITION BITS and PARITY must be
followed by the PSTART signal.
If the PSTART does not came in about 5 seconds (T1) an alarm 7 (73) is output from the turret.
Avoid to change the position code just after the turret LOCKED signal goes high (end of cycle) because this
can be detected as a new position request.
See the diagnostic section to have more details.
AUTOMATIC RECOVER FOR PRESSURE/VALVES PROBLEMS
The turret will attempt three times to lock or unlock before giving an alarm (41 or 51).
If the operator hear the valve operated more timed during the tool change it is necessary to check the cause of
the problem and remove it before a permanent failure happens.
