9. Power Interruption Memory
During the processing of a working piece, there may occur power
interruptions or needed temporary turnoffs, the digital display box will
automatically store the working state (such as the working mode in every axis,
displayed data and the linear error compensation factor) just before every
interruption event in its memory. Every time when the machine is turn on
again, the digital display box will recover to its working state just before the
interruption event after self checking, and the valve just before the interruption
(turn off) event will recover, and the processing will continue.
10. Sleep Switch (no this function for the digital display box with 3-axis
display)
The switch on the back panel of the digital display box may once be
turned off during the processing of a working piece. It is true that the SDS
Series digital box has its interruption memory, but the machine tool may have
been moved after the event. In such a case, when the machine is turned on
again, the working state just before the interruption event will be displayed
again, but this is not the actual new situation. If the operator want to suspend
the processing for his (her) rest time or any time he (she) is occupied by other
thing, the sleep switch can be used to avoid the above mentioned situation.
In not ALE working state, if there a need of Sleep Switch Off, key ,
the digital display box will turn off the display. When restarting the processing,
key , and the box will turn on all the display. No matter how the machine
tool was moved after the display had been turned off, the box will “see” and
“keep in mind” the end state after the machine tool have been moved. When
the display has been turned on again, the displayed working state will be the
actual state.
Note: When the sleep switch has been turned off, the digital display box is
not really in the turnoff sate; if the power switch on the back panel
of the box has been turned off, the sleep switch losses its function.
