measurement mode (TLM) signal was
validated.

• If the stored stroke limit in the parameter
is incorrectly set‚ correct it.
• Reset the alarm with reset‚ and move
the machine in the reverse direction.
• Execute No. 1 reference point return.
• Turn the tool measurement mode signal
input OFF, and move the axis in a safe
direction.
• The operation alarm will turn OFF even
when the sensor signal is turned OFF.
Note) When the tool measurement mode
signal input is turned OFF, the axis
can be moved in either direction.
Pay attention to the movement
direction.
• Execute reference point return
• Reset the absolute position detection
alarm‚ and then perform zero point
return.
• Complete zero point initialization‚ and
then perform zero point return.
