174 Tool Load Exceeded The tool load monitor option is selected and the maximum load
for a tool was exceeded in a feed. This alarm can only occur if the
tool load monitor function is installed in your machine.
175 Ground Fault Detected A ground fault condition was detected in the 115V AC supply. This
can be caused by a short to ground in any of the servo motors,
the tool change motors, the fans, or the oil pump.
176 Over Heat Shutdown An overheat condition persisted for 4.5 minutes and caused an
automatic shutdown.
177 Over Voltage Shutdown An overvoltage condition persisted for 4.5 minutes and caused
an automatic shutdown.
178 Divide by Zero Software Error; Call your dealer.
179 Low Pressure Transmission Oil Spindle coolant oil is low or low pressure condition in lines.
180 Pallet Not Clamped The APC pallet change was not completed for some reason
(pressing E-stop, reset, or feedhold), and an attempt was made
to run the spindle. Run M50 pallet change to reset the machine.
182 X Cable Fault Cable from X-axis encoder does not have valid differential
signals.
183 Y Cable Fault Same as alarm 182.
184 Z Cable Fault Same as alarm 182.
185 A Cable Fault Same as alarm 182.
186 Spindle Not Turning Status from spindle drive indicates it is not at speed when
expected.
187 B Servo Error Too Large Same as alarm 103.
188 B Servo Overload Same as alarm 108.
189 B Motor Overheat Same as alarm 135.
190 B Motor Z Fault Encoder marker pulse count failure. This alarm usually indicates
that the encoder has been damaged and encoder position data
is unreliable. This can also be caused by loose encoder
connectors.
191 B Limit Switch Same as alarm 148.
192 B Axis Z Ch Missing Broken wires or encoder contamination. All servos are turned off.
This Ch Missing can also be caused by loose encoder
connectors.
