273 C 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.
274 C Limit Switch Same as alarm 145.
275 C 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.
276 C Axis Drive Fault Same as alarm 161.
277 C Zero Ret Margin Too Small Same as alarm 165.
278 C Cable Fault Same as alarm 182.
279 X Axis Linear Scale Z Fault Encoder marker pulse count failure. This alarm usually indicates
that the Z Fault encoder has been damaged and encoder
position data is unreliable. This can also be caused by loose
scale connectors.
280 Y Axis Linear Scale Z Fault Encoder marker pulse count failure. This alarm usually indicates
that the Z Fault encoder has been damaged and encoder
position data is unreliable. This can also be caused by loose
scale connectors.
281 Z Axis Linear Scale Z Fault Encoder marker pulse count failure. This alarm usually indicates
that the Z Fault encoder has been damaged and encoder
position data is unreliable. This can also be caused by loose
scale connectors.
282 A Axis Linear Scale Z Fault Encoder marker pulse count failure. This alarm usually indicates
that the Z Fault encoder has been damaged and encoder
position data is unreliable. This can also be caused by loose
encoder connectors.
283 X Axis Linear Scale Z CH Missing Broken wires or encoder contamination. All servos are turned off.
This Z Channel Missing can also be caused by loose scale
connectors.
284 Y Axis Linear Scale Z CH Missing Broken wires or encoder contamination. All servos are turned off.
This Z Channel Missing can also be caused by loose encoder
connectors.
285 Z Axis Linear Scale Z CH Missing Broken wires or encoder contamination. All servos are turned off.
This Z Channel Missing can also be caused by loose encoder
connectors.
286 A Axis Linear Scale Z CH Missing Broken wires or encoder contamination. All servos are turned off.
This Z Channel Missing can also be caused by loose encoder
connectors.
287 X Axis Linear Scale Cable Fault Cable from X-axis scale does not have valid differential signals.
