(Note 6) Automatic initialization cannot be started in the following cases. The message "T01 CAN'T

CYCLE ST" will appear if starting is attempted.
• When "#0 INIT. SET" is not set.
• When the "#2 ZERO" setting is inappropriate.
• When "#2055 pushf" is not set.
• When "Z71 DETECTOR ERROR 0005" has occurred.
In the above cases, if the "#2 ZERO" setting is inappropriate, this means that the relation of
"#2 ZERO" and "2037 G53ofs" is inappropriate. In other words, if "#2 ZERO" is smaller than
the "#2037 G53ofs", the machine end stopper will be located between the basic machine
coordinate system zero point and machine zero point, so automatic initialization cannot be
started. If "#2 ZERO" is set to 0, the machine end stopper direction will not be set, so
automatic initialization cannot be started.
(Refer to the following diagram)

Looking from the basic machine coordinate system zero point, the
machine zero point is farther from the machine end stopper, so
reference point return cannot be carried out.

When the "#2 ZERO" setting is 0, the
basic machine coordinate system
zero point is on the machine end
stopper, so the pushing and
movement direction cannot be
pinpointed.
