DISPLAY SIGNIF SOLUTION
E A013 SEMIAUTO MODE CANNOT BE ENTERED
The theta cw or ccw limit sensor is on, and therefore semiauto cannot be entered.
2) B-type Errors (disabled key operation)
DISPLAY SIGNIF SOLUTION
E B001 DISABLED KEY PRESSED
During certain sequential operations (ie. SEMI-AUTO, FULL-AUTO) the operation
of other, unrelated (ie. INDEX) keys is suspended. If such a key is pressed, this error
code appears without disrupting operation.
3) C-type Errors (mechanical failures during operation)

SET-UP FAILURE
This error code is initiated when the Z-axis lower limit sensor fails to sense contact
with the chuck table during set-up.
Check this sensor and take appropriate action.
FAILURE TO POSITION CHUCK TABLE IN CENTER
Instead of stopping at the center, the table stops when it reaches the X-axis left or right
end of the Y-axis front or rear end. In most cases, failure to sense the center is due to
malfunction of either the X- or Y-axis center sensors, so perform a check of the center
sensors.
FAILURE TO POSITION TABLE UNDER SCOPE
In this case the X-axis goes to either the left or right end limit and stops. The cause is
usually a malfunction of the sensor which determines the table position under the
scope, so inspect this sensor.
FAILURE TO RISE TO SET HEIGHT AFTER SET-UP
Spindle stops at upper limit rather than at the input height.
This is usually caused by a set-up value which is not within the specified range, so
check the value and, when corrected, push the SET-UP key again.
