YASNAC PCNC I/O Signal Function Manual Chapter 6: Operation Support Functions
6.12 Edit Lock Input Signal
The edit lock input signal protects part programs stored in the PCNC part program memory from
being altered.
When the EDTLK input signal is “closed”, key operation of the [INSET], [ALTER] and
[ERASE] keys, and the data storing opertion are ignored.
If program edit operation is attempted in this state, the following warning message is displayed:
“EDIT LOCK!”
6.13 Automatic Mode Handle Offset Input Signal
When the HOFS input signal is “closed”, axis movement generated by the pulse handle can be
overlapped with the axis movement executed in the automatic operation.
The axis for which overlapping of axis movement by the pulse handle is the one which
selected by the pulse handle feed axis selection input signal. Axis movement distance
per pulse can be changed by setting the multiplication ratio setting switch.
IMPORTANT!
1. Axis movement by the automatic mode handle offset function is always valid even during
block stop or when a block which does not include axis movement commands is executed.
2. If the axis interlock input (*ITX to *IT5) signal is “closed”, axis movement by the automatic
mode handle offset function is not possible.
6.14 Interruption Point Return Input Signal
By moving axes manually after interrupting automatic operation to remove chips or per-
forming measurements, close the CPRN input signal and then the manual axis feed direc-
tion selection input signal in the direction the axis can move to the point where operation
was interrupted, and the axis returns to the operation interrupted point.
Note that if the reference point return input or the second reference point return input signal
is “closed”, the axis does not return to the operation interrupted point, but returns to the ref-
erence point or to the second reference point.
