flow is incorrect.
There is a problem with the
voltage to the turret clamp /
unclamp solenoid.
There is a problem with the
turret clamp / unclamp
solenoid.
There is a problem with the
clamp/unclamp cylinder.
The turret unclamp sensor is
faulty or out of adjustment.
Turret is out of alignment.
Mechanical binding of turret.
The turret clamp sensor is
faulty or out of adjustment.
Check the incoming air
supply.
Check the voltage to the
turret clamp / unclamp
solenoid.
Check the turret clamp /
unclamp solenoid.
Test the air cylinder for
faulty piston seal.
Check the turret unclamp
sensor.
Check Turret/Motor
coupling adjustment.
Check turret for possible
turret o-ring damage or
chip intrusion.
Check the turret clamp
sensor.
Unusual noise as the turret rotates
Alarm 106 A-AXIS POSITION ERROR
Axis rotating slowly, hesitating to rotate.
Tool Turret Die springs are
broken.
The servo motor has an
electrical fault.
Mechanical obstruction.
Contaminated HPC Pressure
Sensor cable.
Remove Tool Turret to
inspect or replace springs.
Go to DIY servo system
trouble shooting.
Inspect turret for possible
obstruction or binding
during rotation.
Check the HPC Pressure
cable for coolant
contamination.

Solenoid
Corrective Action:
CALM System (All solenoids located in the lube panel)
Use needle tipped probes and take care not to touch probes tips together when checking voltage.
Set the meter to AC voltage.
In MDI command an M43 and press cycle start to unclamp the turret.
Measure the voltage to the clamp and unclamp solenoid. The solenoids are inside the CALM (consolidated air/lubrication
manifold) panel. The voltage should measure 120 VAC.
If there is no voltage, refer to:
• NEXT GENERATION CONTROL - I/O PCB - TROUBLESHOOTING GUIDE
• I/O PCB - TROUBLESHOOTING GUIDE (CLASSIC HAAS CONTROL)
If voltage at the I/O is correct inspect the cable.
If the solenoid appears to be faulty, go to SOLENOID TROUBLESHOOTING GUIDE.
Pre CALM System
Power off, lock and tag out the machine.
Remove the left rear machine enclosure panel.
Locate the clamp/unclamp solenoid and power connection behind the Tool Turret assembly.
Remove lock out tags, power up and zero return the machine.
Use needle tipped probes and take care not to touch probes tips together when checking voltage.
Set the meter to AC voltage.
In MDI command an M43 and press cycle start to unclamp the turret.
Measure the voltage at the solenoid power connection. Do Not unplug the cable. The voltage should measure 120 VAC.
If there is no voltage, refer to:
• NEXT GENERATION CONTROL - I/O PCB - TROUBLESHOOTING GUIDE
• I/O PCB - TROUBLESHOOTING GUIDE (CLASSIC HAAS CONTROL)
If voltage at the I/O is correct inspect the cable.
If the solenoid appears to be faulty, go to SOLENOID TROUBLESHOOTING GUIDE.

Air Cylinder
Clamp/Unclamp Sensors
Corrective Action:
With the turret clamped test the air cylinder for
faulty piston seal.
Remove the upper hose (unclamp) on the cylinder.
If air is escaping from the upper hose (unclamp)
connection on the cylinder the cylinder piston seal
is bad and piston should be replaced.
Corrective Action:
Turret Die Springs
Check the turret unclamp and clamp sensors.
Use a magnet and pass it over the sensors. Watch
the diagnostics screen to make sure they activate
with the magnet.
If the magnet did not activate the sensors inspect
the cables. If the cables are not damaged then the
sensor will need to be replaced.
If the sensors were activated then they may need to
be adjusted. Verify the motor coupler alignment
before adjusting sensors. Refer to ST-10/10Y,
SL-10-30, TL-15/25, HL-1-6 - TURRET LOCK AND
UNLOCKED SENSORS - ADJUSTMENT procedure.
Corrective Action:
With the turret clamped, rotate the turret back and
forth by hand. If there is movement in the turret the
die springs are broken and need to be replaced.
Refer to HL/SL/ST-10 - TURRET -
REPLACEMENT from the manual. Once the turret is
removed the springs can be replaced.

Mechanical Binding
Corrective Action:
If the o-ring under the rear turret chip skirt fails it can cause binding and prevent the turret from rotating into position. A
failed o-ring will also allow for coolant and chip intrusion into the back side of the turret. In this case the turret should be
removed to clear the chips and inspected for possible damage.
A failed o-ring will also allow for coolant and chip intrusion into the back side of the turret. In this case the turret should be
removed to clear the chips and inspect for possible damage.
Alignment
If the turret is knocked out of alignment you may have to re-align the turret motor coupler.
Refer to SL-10/20/30, ST-10/10Y - MOTOR COUPLING - ALIGNMENT procedure.
If the turret is knocked out of alingment a full geometry inspection should be done. Make corrections as needed.
Servo Motor
Corrective Action:
The servo motor has an electrical fault. Possible failed motor, bad or contaminated cable connection, a damaged cable, or
failed amplifier.
Refer to SIGMA 1 - AXIS SERVO MOTOR AND CABLES - TROUBLESHOOTING GUIDE or SIGMA 5 - AXIS SERVO
MOTOR AND CABLES - TROUBLESHOOTING GUIDE for detailed information.
