Override
The feedrate override and the rapid traverse override are tuned when the program is running or
the feed hold is valid, and the speed is immediate valid after tuning. For the tuning operation,
see Section
Operation, 4.5.5 Override tune
.
Before executing each block, the system prompts Feedrate Zero when the feedrate override is
zero. When the feedrate override is tuned to zero in the course of program running, the program
will stop and the system has no the prompt. The program continues to run when the feedrate
override is not zero.
4.5.7 Program Reference Point Return in AUTO Mode
To simplifying operations, the part program can be started wherever the slider is placed after
defining the workpiece coordinate system and the program reference point. At the moment, the
first traverse command of part program must be G00 and must be positioned with X, Z absolute
coordinates. In this case, the operation of program reference point return by pressing key or with
G26/G27/G29 is to return to the defined program reference point. After using G26/G27/G29, use
G00 to again position Z/X absolute coordinate (i.e. G00 Z_ X_) to gain the qualified machining.
After executing the program reference point return by pressing key, the system will automatically
point to the first block. At the moment, if is pressed, the system runs from the first
block.
4.5.8 Feed Hold Knob in Automatic Run
GSK928TEII CNC System is equipped with an external interface of feed/spindle hold knob.
Traverse or stop the spindle and the slider when the knob is placed on the different position. Use
the knob to control conveniently the starting/stopping of spindle and the slide. There are three
positions of feed hold knob and its function as follows:
Position 1: permit the spindle to rotate and the slider to traverse.
Position 2: permit the spindle to rotate and forbid the slider to traverse.
Position 3: forbid the spindle to rotate and the slider to traverse.
