To avoid this condition it is suggested, after carrying the m achine at the norm al condition of working to do this operation:

为了避免这种情况发生，在机床恢复到正常工作条件下后，执行下面一系列操作：

Reset the channel 2复位通道2

Reset the channel 1复位通道1

Press the key T4. 按下T4键

So the starting conditions were reset and the m achine m ay restart running.

The led means that the operation has been started up.

用这种方法，启动条件被恢复，机床可重新正常工作。灯仅表示开始操作。

T6 key:

The m achine, as it was conceived, doesn’t allow the operator to us it in aut o m atic or semiaut o m atic, if at least one of the axes has been 

referenced (spindle excluded). This is necessary in order to avoid any aut o m atic operation providing the referencing of the axes (i.e the au 

t o m atic tool change). A special key (T6) has been provided in order to allow the operator to get out from a critical situation by overlooking

 the taking up of the reference of one or more axes. 

工根据机床设计即使只剩有一个轴还没有回参考点的情况下都不允许操作者使用自动或半自动模式。为了避免粗自动操作提供轴参考（例如自动换刀）

，这是必要的。为了这个目标，T6键能使一个或多个轴在一些特殊情况下忽略参考点以摆脱危险的情况。

Of course, the operator has to be aware that using this pushbutton the m achine is not working at full safety conditions, and so he has to be
