ALARMS

96-8000
158 Video/Keyboard PCB Failure Internal circuit board problem. The VIDEO PCB in the processor
stack istested at power-on. This could also be caused by a short
in the front panel membrane keypad. Call your dealer.
159 Keyboard Failure Keyboard shorted or button pressed at power on. A power-on test
of the membrane keypad has found a shorted button. It can also
be caused by a short in the cable from the main cabinet or by
holding a switch down during power-on.
160 Low Voltage The line voltage to control is too low. This alarm occurs when the
AC line voltage drops more than 10% below nominal.
161 X-Axis Drive Fault Current in X servo motor beyond limit. Possibly caused by a
stalled or overloaded motor. The servos are turned off. This can
be caused by running a short distance into a mechanical stop. It
can also be caused by a short in the motor or a short of one
motor lead to ground.
162 Y-Axis Drive Fault Same as alarm 161.
163 Z-Axis Drive Fault Same as alarm 161.
164 A-Axis Drive Fault Same as alarm 161.
165 X Zero Ret Margin Too Small This alarm will occur if the home/limit switches move or are
misadjusted.
This alarm indicates that the zero return position may not be
consistent from one zero return to the next. The encoder Z
channel signal must occur between 1/8 and 7/8 revolution of
where the home switch releases. This will not turn the servos off
but will stop the zero return operation.
166 Y Zero Ret Margin Too Small Same as alarm 165.
167 Z Zero Ret Margin Too Small Same as alarm 165.
168 A Zero Ret Margin Too Small This alarm will occur if the home/limit switches move or are
misadjusted. This alarm indicates that the zero return position
may not be consistent from one zero return to the next. The
encoder Z channel signal must occur between 1/8 and 7/8
revolution of where the home switch releases. This will not turn
the servos off but will stop the zero return operation.
169 Spindle Direction Fault Problem with rigid tapping hardware. The spindle started turning
in the wrong direction.
170 Phase Loss Problem with incoming line voltage. This usually indicates that
there was a transient loss of input power to the machine.
173 Spindle Ref Signal Missing The Z channel pulse from the spindle encoder is missing for
hard tapping synchronization.
