1.1 Errors Displayed in the Second Display Area
There are several types of errors displayed on the machine. One type of error causes an
emergency stop, which cuts off the 200 V power supply to the machine. Another type of
error does not cause an emergency stop but interrupts automatic operation or prevents it
from being started. Yet another type of error only displays a message but does not stop
machine operation.
If an emergency stop occurs, the Y-table is stopped and the 200 V power supply to the
machine is cut off. The RESET button has to be pressed to start the machine operation
again. The message “Emergency Stop" is displayed in red at the top of the second
display area and one of the causes in the list below is displayed in yellow.
Emergency SW Pressed

Remedy: After releasing the EMERGENCY STOP button press the RESET button to

Press the [RESET] button and inch the displayed axis away
from the sensor.
2. For the Z-axis
Check the Z-axis zero position value to see if something is
abnormal. Otherwise, verify the overtravel limit settings
in Proper data.
Z1-axis maximum value Travel_limit_max.Z1 + 30
Z2-axis maximum value Travel_limit_max.Z2 + 30
Z3-axis maximum value Travel_limit_max.Z3 + 30
Z1-axis minimum value Travel_limit_min.Z1 - 30
Z2-axis minimum value Travel_limit_min.Z2 - 30
Z3-axis minimum value Travel_limit_min.Z3 - 30
