113 Shuttle In Fault Tool changer not completely to right. During a tool changer operation
the tool in/out shuttle failed to get to the in position. Parameters 62 and 63 can adjust the time-
out times. This alarm can be caused by anything that jams the motion of the slide or by the
presence of a tool in the pocket facing the spindle. A loss of power to the tool changer can also
cause this, so check CB5 and relays 1-8, 2-1, and 2-2.
114 Shuttle Out Fault Tool changer not completely to left. During a tool change operation the tool in/out shuttle failed
to get to the out position. Parameters 62 and 63 can adjust the time-out times. This alarm can
be caused by anything that jams the motion of the slide or by the presence of a tool in the
pocket facing the spindle. A loss of power to the tool changer can also cause this, so check
CB5 and relays 1-8, 2-1, and 2-2.
115 Turret Rotate Fault Tool carousel motor not in position. During a tool changer operation the tool turret failed to
start moving or failed to stop at the right position. Parameters 60 and 61 can adjust the time-
out times. This alarm can be caused by anything that jams the rotation of the turret. A loss of
power to the tool changer can also cause this, so check CB5 and relays 1-8, 2-3, and 2-4.
116 Spindle Orientation Fault Spindle did not orient correctly. During a spindle orientation function, the spindle is rotated
until the lock pin drops in; but the lock pin never dropped. Parameters 66, 70, 73, and 74 can
adjust the time-out times. This can be caused by a trip of circuit breaker CB4, a lack of air
pressure, or too much friction with the orientation pin.
117 Spindle High Gear Fault For Vertical Mills only. Gearbox did not shift into high gear. During a change to high gear, the
spindle is rotated slowly while air pressure is used to move the gears but the high 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.
118 Spindle Low Gear Fault For Vertical Mills only. 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 high 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 (about 255 volts when wired for 240 or 235 when
wired for 208). 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. Check your incom
ing air pressure for at least 100 PSI and ensure that the regulator is set at 85 PSI.
121 Low Lub or Way lube is low or empty or there is no lube pressure or too high a pressure.
Low Pressure Check tank at rear of mill and below control cabinet. Also check connector P5 on the side of the
control cabinet. Check that the lube lines are not blocked.
122 Control Overheat The control internal temperature is above 150 degrees F. This can be caused by almost
anything in the control overheating. But is usually caused by overheat of the two regen resis
tors for servos and spindle drive. This alarm will also 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 for 4.5 minutes, an automatic shutdown will begin.
