118 Spindle Low Gear Fault Gearbox did not shift into low gear. During a change to low gear,
the spindle is rotated slowly while air pressure is used to move
the gears but the low gear sensor was not detected in time.
Parameters 67, 70 and 75 can adjust the time-out times. Check
the air pressure, the solenoids circuit breaker CB4, and the
spindle drive.
119 Over Voltage Incoming line voltage is above maximum. The servos will be
turned off and the spindle, tool changer, and coolant pump will
stop. If this condition remains for 4.5 minutes, an automatic
shutdown will begin.
120 Low Air Pressure Air pressure dropped below 80 PSI for a period defined by
Parameter 76. The LOW AIR PR alarm will appear on the screen
as soon as the pressure gets low, and this alarm appears after
some time has elapsed. Check your incoming air pressure for at
least 100 PSI and ensure that the regulator is set at 85 PSI.
121 Low Lube or Low Pressure Way lube is low or empty or there is no lube pressure or too high
a pressure. Check tank at rear of mill and below control cabinet.
Also check connector on the side of the control cabinet. Check
that the lube lines are not blocked.
122 Regen Overheat The regenerative load temperature is above a safe limit. This
alarm will turn off the servos, spindle drive, coolant pump, and
tool changer. One common cause of this overheat condition is an
input line voltage too high. If this condition remains high for 4.5
minutes, an automatic shutdown will begin. It can also be
caused by a high start/stop duty cycle of spindle.
123 Spindle Drive Fault Failure of spindle drive, motor or regen load. This can be caused
by a shorted motor, overvoltage, overcurrent, undervoltage, failure
of drive, or shorted or open regen load. Undervoltage and
overvoltage of DC bus are also reported as alarms 160 and 119,
respectively.
124 Low Battery Memory batteries need replacing within 30 days. This alarm is
only generated at power on and indicates that the 3.3 volt Lithium
battery is below 2.5 volts. If this is not corrected within about 30
days, you may lose your stored programs, parameters, offsets,
and settings.
125 Shuttle fault Tool shuttle not initialized at power on, CYCLE START or spindle
motion command. This means that the tool shuttle was not fully
retracted to the Out position.
126 Gear Fault Gearshifter is out of position when a command is given to rotate
the spindle. This means that the two speed gear box is not in
either high or low gear but is somewhere in between. Check the
air pressure, the solenoids circuit breaker CB4, and the spindle
drive.
127 No Turret Mark Tool carousel motor not in position. The turret motor only stops in
one position indicated by a switch and cam on the Geneva
mechanism. This alarm is only generated at power-on. The
AUTO ALL AXES button will correct this but be sure that the pocket
facing the spindle afterwards does not contain a tool.
