8. Manual intervention
If manual intervention is performed during programmed operation of the machine, the tool path may vary when
the machine is restarted. Before restarting the machine after manual intervention, therefore, confirm the settings of
the manual absolute switches, parameters, and absolute/incremental command mode.
9. Feed hold, override, and single block
The feed hold, feedrate override, and single block functions can be disabled using custom macro system variable
#3004. Be careful when operating the machine in this case.
10. Dry run
Usually, a dry run is used to confirm the operation of the machine. During a dry run, the machine operates at dry
run speed, which differs from the corresponding programmed feedrate. Note that the dry run speed may
sometimes be higher than the programmed feed rate.
11. Cutter and tool nose radius compensation in MDI mode
Pay careful attention to a tool path specified by a command in MDI mode, because tool nose radius compensation
is not applied. When a command is entered from the MDI to interrupt in automatic operation in tool nose radius
compensation mode, pay particular attention to the tool path when automatic operation is subsequently resumed.
Refer to the descriptions of the corresponding functions for details.
12. Program editing
If the machine is stopped, after which the machining program is edited (modification, insertion, or deletion), the
machine may behave unexpectedly if machining is resumed under the control of that program. Basically, do not
modify, insert, or delete commands from a machining program while it is in use.
5 WARNINGS RELATED TO DAILY MAINTENANCE
WARNING
1. Memory backup battery replacement
When replacing the memory backup batteries, keep the power to the machine (CNC) turned on, and apply an
emergency stop to the machine. Because this work is performed with the power on and the cabinet open, only
those personnel who have received approved safety and maintenance training may perform this work.
When replacing the batteries, be careful not to touch the high
–
voltage circuits (marked and fitted with an
insulating cover).Touching the uncovered high
–
voltage circuits presents an extremely dangerous electric shock
hazard.
NOTE:The CNC uses batteries to preserve the contents of its memory, because it must retain data such as
programs, offsets, and parameters even while external power is not applied. If the battery voltage drops, a low
battery voltage alarm is displayed on the machine operator’s panel or screen. When a low battery voltage alarm
is displayed, replace the batteries within a week. Otherwise, the contents of the CNC memory will be lost. Refer
to the maintenance section of the operator’s manual for details of the battery replacement procedure.
2. Absolute pulse coder battery replacement
When replacing the memory backup batteries, keep the power to the machine (CNC) turned on, and apply an
emergency stop to the machine. Because this work is performed with the power on and the cabinet open, only
those personnel who have received approved safety and maintenance training may perform this work. When
replacing the batteries, be careful not to touch the high

voltage circuits (marked and fitted with an insulating
