通过按下轴选择键之一，同样能识别轴的通路打开或关闭。在上述情况下，灯灭或亮都表示轴没有任何通路，而灯闪则表示轴的通路打开。

T7 key:

The key T7 serves to the m anual uncla mping of the attachment. Being that a dangerous operation, both for the operator and for the integrity 

of the attachment we have provided that the m anual uncla mping takes place only by selecting it on the headstock control panel and by 

pressing the T7 key. This avoids that the operator could wrongly uncla mps the attachment instead of a tool. The led ON shows only that 

the key has been selected.

T7键用于手动松开附件。此操作会对操作者和附件本身的完整性造成危险，使用选择附件和主轴箱面板上的松开或按下T7键可实现手动松开。

这就能预防操作者进行错误操作（本要松开刀 具却松开了附件）。此键相关的信号灯仅用来表示该键被按下了。

T8 key: 

By the key M11 active and the channel 1 in Jog mode it is possible to uncla mps all the m achine axes except for the B axis of the table for

 which it is necessary at each control waiting for its uncla mping.

在手动方式通道1下通过按M11键就能放松除了工作台B轴和A轴之外的所有 机床轴，而它们的放松是由每次控制要求的。

The key is of bistable type so the first selection will activate it while the next one will deactivate it.

此键是双向稳定的，第一次按启动，随后按则禁止。
