34 | Part 2
1. If the 1st Ref. Rtn. is executed in manual, the axis will be traversed rapidly. Thus it
needs to pay attention.
And rapid traverse speed on Ref. Rtn. is restricted by 50% except that manual rapid
traverse speed is set to the value less than machine specification.
2. Ref. Rtn. cannot be executed in the status of machine as follows.
- Machine is in emergency stop status.
- Machine lock status.
- Q-setter is down.
- Machine mode is not Ref. Pt. mode but another mode.
- Jog traverse of axis is impossible.
3. In order to stop Ref. Rtn. by one touch type, execute the operation as follows.
- Press emergency stop switch
- Press feed hold switch
- Press "CNC RESET" button in operation panel.
- Change axis feedrate override switch into 0%.
4. C-axis can be clamped not to execute axis traversing in order to execute machining
such as tapping etc. In this case, if C-axis is clamped, Ref. Rtn. Of C-axis is
impossible.
