1 Only the modes shown below can be selected by soft
switches. When the mode for DNC operation is to be
equipped, for example, all control switches for mode
selection should be on the machine operator’s panel or a
general–purpose soft switch should be used to select the
mode for DNC operation.
Soft switches available for mode selection
⋅ Manual data input
⋅ Automatic operation
⋅ Memory edit
⋅ Manual handle / step feed
⋅ Jog feed

2 Only one soft switch is available for protection key.
However, four input signals are available for protection key
(KEY1, KEY2, KEY3 and KEY4). Generally, four input
signals are simultaneously turned to “1” or “0” according to
the state of the soft switch for protection keys.
3 When the soft switch for feed hold is turned on, output signal
*SPO is turned to “0”. At this time, the PMC turns feed hold
signal *SP to “0”.
In contrast to the above, when the soft switch for feed hold
is turned off, output signal *SPO is turned ”1” and the PMC
turns signal *SP to “1”. For soft switches other than general
soft switches, when an output signal informing the state of
a soft switch is turned to “1”, the corresponding input signal
is turned to “1”.
