Functioning:功能
The functioning of the main control panel is quite complex because it carries out whether the normal functions provided by Siemens, or the specific operations planned by the operator and both.
主面板的功能相当复杂，因为它既包含西门子提供的标准功能，还有上述功能用于专门操作。
To not overload the subject we decide to leave out the description of the standard functions Siemens, which you can find on the relevant use and maintenance manuals. In particular we do not treat the unit MMC that is entirely managed by Siemens. The only intervention made by the manufacturer is that of inhibit some functions or configure some pages in order to better adapt it to the specific functions of the machine.
为了避免项目繁重，我方省略了西门子功能性标准的描述，您可参阅西门子提供的专用手册。特别是，MMC单元我方也不做涉及了，因为此单元全由西门子管理而机床制造上唯一干涉的地方就是限制了一些功能或配置使它更适合机床。
So we start with the keys placed under the user interface MMC.
所以我们从MMC用户接口下的按钮开始介绍。
“Machine ON” Push Button: “机床启动”按钮
The key “machine ON” serves to reset the safety submodule (emergency, overtravel, spindle) in order to operate the auxiliaries and the machine axes. At the first switching on the relevant lamp is OFF. This condition means that all the functions of the machine are inhibit and at least one safety submodule has not been reset.
“机床启动”按钮用来恢复安全模式（紧急情况，超行程，主轴），打开辅助开关和各轴。第一次启动的时候，按钮相关的信号灯是暗的。此情况表明机床的所有活动被禁止且至少有一种安全模式没有被恢复。
If the machine condition does it allow, after the first selection of the key all the safety submodules are reset (machine not in overtravel, emergencies not set, headstock control panel deactivated); on the contrary, the state of inhibition will remain active. When the safety submodules are reset the lamp flashes slowly. In this new state a second selection of the key “machine ON” produces the activation of the aux iliaries and so the machine is operative with the only exception that the axes are not powered.
直到第一次按按钮，在机床条件允许的条件下安全模式才被恢复（没有超行程，紧急按钮没有按下，主面板不可用）；否则，仍保持禁止状态。当安全模式被恢复时，信号灯慢闪。在这种新的状态下，按住“机床启动”按钮一秒激活辅助开关，机床启动，但轴未进给。
The quick flashing of the lamp shows the new condition.
用灯的快闪来表示这种情况。
With the further selection of the key the axes line is powered. It is conditioned by the fact that it would be the DC an AC input and that no axis would be in overtravel.
更长的按住此按钮，则激活轴线。在这种状态下，有交直流进给没有轴超行程。
The lamp shows this new condition ON.
通过灯接通来表示这种新状态。
If at least one axis is in overtravel the input at the axes line is abled only for the time in which the key is pressed, provided that the channel 1 would be in the JOG mode. In case the axis is in overtravel it is necessary to keep pressed the key “Machine ON” as long as to control the axis out of the overtravel.
如果至少有一根轴超行程，则只有按下按钮时才轴线进给并使通道1处于手动模式。如果轴超行程，则按住“机床启动”按钮可以避免。
After operating the axes line it keeps this condition as long as one of the above mentioned conditions will occur: emergency state of the machine, wrong DC or AC input, axis in overtravel. Among these events only the emergency state disables also the auxiliaries, this means that except for this case the relevant lamp flashes quickly.
一旦轴线激活，则保持这种情况直到状态改变，诸如：机床处于紧急状态，直流或交流进给不正确或者轴再次超行程。在这些状态中，只有机床处于紧急状态才关闭辅助开关；这意味着，除了这种情况，相关的信号灯仅保持快闪。
The use of the headstock control panel causes the activation of the spindle safety submodule. If this happens it is necessary to reset the submodule making sure that the attachments and the tools would be clamped and the selector of the headstock control panel would be in the central position and then press the “Machine ON”. For further information see the section “Headstock control panel”.
主控制面板的使用将激活主轴安全模式。确保附件和刀具夹紧且面板选择器处于中心位置，然后按下“机床启动”按钮，则安全模式随后将被恢复。祥见“主控制面板”。
“Alarm Reset” Push Button: “报警复位”按钮
The selection of the key “Alarm reset” disables all alarms; for further information see the section “alarms and messages”. The relevant lamp is normally OFF and it flashes at each alarm or message out of the normal running of the machine.
“报警复位”按钮用来撤销所有的报警，只要按一下按钮即可（详见“报警和信息”）。按钮相关的信号灯正常下是暗的，每闪烁一次就有一次关于机床的不正常机能的报警或信息显示。
In particular, the lamp doesn’t flash during the axis unclamping being that a transitory condition belonging to the normal running of the machine.
特别是，信号灯不闪的时候说明轴释放，这种情况是短暂的，且为机床正常运行的一部分。
Buzzer:蜂鸣器
The “Buzzer” or hooter serves to draw the attention of the operator owing to the particular conditions that normally he couldn’t feel.
蜂鸣器或者声音报警是用于引起操作者注意那些不可转移的特殊情况。
It gives an impulse each time the Renishaw bends and in any case it shows the condition reached.
它每次发出一个脉冲来表示Renishaw探头弯曲或者发生了情况。
It gives an impulse also when abling the control of the Renishaw by M50 but this last is not yet activated.
也可以表示带M50功能的Renishaw控制启动但Renishaw还未激活。
Coolant:冷却液
The coolant management (or the air supply on the workpiece) is carried out whether in manual mode or in automatic. Doubtfully the first one prevails on the second one.
可手动和自动控制冷却液（或气用于工件）。毫无疑问，手动优先。
For this purpose, it has been provided on the main control panel a two positions selector key: manual or automatic mode.
为此，主面板上设置了一个2位置选择键：手动或自动模式。
When the selector is in the automatic mode the key for the external and internal coolant is inhibit and its control is assigned to the NC.
如果该选择键处于自动模式位置，则控制内外冷却液的按钮停止而由NC控制。
In fact, by the functions M7, M8, M97, M98 it is possible to control the internal and external coolant, the air supply inside and outside the workpiece respectively, while the function M9 disables all these functions.
事实上，M7,M8, M97, M98功能可以分别控制内外冷却液，工件内外气体供给，但M9关闭了这些功能。
The lamp relevant to the internal, external coolant or the air supply (led on the push button INTERNAL AIR – EXTERNAL AIR on the operator control panel) will be ON when the function is active, and OFF on the contrary.
当功能有效时，内外冷却液/气（操作面板上的内/外气键）的信号灯点亮，反之熄灭。
With the selector key in manual mode the coolant supply will be interrupted and its reactivation depends on the next key selection. The first selection of the key serves to activate the control and the second one to deactivate it.
如果该选择键处于手动模式位置，则当前可用的冷却液被阻断，再次激活则需按键。第一次按键激活控制，第二次按则停止。
Also in this case the lamps ON will state the function active, while if they are OFF the function is not controlled.
这种情况下，灯亮说明功能可用反之则不能控制。
Besides the above-mentioned state there is a state of flashing lamp, which happens whenever a function operated by the program is disabled manually. In this case with the selector in automatic mode the control will be immediately reset.
除了这些情况以外，灯闪说明程序手动停止来使功能激活。在此情况下，使选择键处于自动模式下，就能立即恢复控制。
Handwheel:手轮
This key serves to operate the handwheel placed from the side of the main control panel and it allows moving all axes exclusively in JOG mode. Its operation is also conditioned by the state of the SIEMENS mobile control panel, because is not possible to move the axes in JOG from two different equipments at the same time.
此钥匙用于激活位于主控制面板边上的手轮，它可以使所有轴以手动模式移动。它的操作允许与否由西门子控制面板的当前状态所决定，因为不可能在手动模式下通过两个不同的装置同时来移动轴。
Joystick for the operator platform:操作平台控制杆
Through a joystick at 4 positions it is possible to move the platform independently from the machine movement in order to have a better sight of the workpiece.
通过4位置控制杆，可以从机床运动中单独移动平台以能更好地看见工件。BHG Selector-Key: BHG钥匙选择器
The selector-key BHG enables activate or deactivate the BHG control panel. The selector key on the BHG serves to deactivate its functionality even keeping the connection with the NC. With the electrical connection off, also the mush-room-head pushbutton and the safety device “dead man” are inhibit.
BHG钥匙选择器用来打开或关闭BHG面板。钥匙选择器处于BHG无作用状态则停止功能，即便在与NC通讯中。蘑菇形紧急按钮和安全设备“备用”无效。Spindle JOG:主轴手动模式选择器
The selector for the clockwise and counterclockwise JOG of the spindle has the same functionality as of that placed on the operator control panel if they are selected together with the pushbutton for the spindle rotation and with the channel 1 in JOG mode.
操作面板上的主轴顺时针手动模式和逆时针手动模式有相同的功能，当与主轴旋转按钮一起按下时通道1处于手动模式。
Without pressing this pushbutton the selector doesn’t work. Unlike the keys on the operator control panel these last ones operate also in concomitance with the movement of an other axis. 没有此按钮，则选择器不进行任何操作。与操作控制面板上键不同的是最后的几个键操作时伴随着另一个轴的移动。
Chip conveyor:铁屑输送器
The chip conveyor can be moved whether in automatic or in manual mode. The first mode is operated by the functions M76 (ON) and M77 (OFF) while the second one depends on the state of the selector on “Manual functioning forward/backwards” and of the relevant pushbutton “Start” and “Stop”.
铁屑输送器能用手动和自动两种模式控制。第一种模式由M76（接通）和M77（切断）功能控制，第二种取决于“手动功能向前/向后”选择键的状态以及相关的“开始”“停止”按钮。
The lamps show at each time the state of the chip conveyor with the following meaning:
信号灯显示铁屑输送器的状况，含义如下：
“Start” lamp ON when the chip conveyor is moving in automatic or manual mode.
信号灯亮说明输送器在自动或手动模式下工作。
“Stop” lamp ON when the ch ip conveyor is stopped.
灯暗说明停止工作。
“Start” lamp flashing when the movement of the chip conveyor is prevented due to the change of the selector from manual mode to automatic or viceversa if the conveyor is still moving or finally to the microswitch “chip conveyor jammed”.
信号灯闪说明铁屑输送器运动被阻止，可能由于输送器运动时选择键更换从手动模式转为自动或相反，或最终转为微型开关“铁屑输送器堵塞”。
Operator Push Button (Custom Keys):操作员按钮（客户键）
As per the MMC we do not detail its functionality (see the SIEMENS description) but we will consider only the part relevant to the “Customer” keys. Only the manufacturer of the machine provides these keys for the management. There are 15 keys and their function depends to the planning made by the manufacturer.
关于MMC我们不作详述，您可参阅西门子书，但介绍“用户”键的管理部分，即机床制造商掌控的这些键。总共有15个键，他们的功能取决于制造商。
The numeration is made as usually from left to right and up and down.
编号方式为从左到右，从上到下。

Here a short description of their function. 键的简短描述
T1 key:
Not used.未使用
T2 key:
Not used.未使用
T3 key:
Not used.未使用
T4 key:
The T4 key is used during the manual tool change and it informs the NC that the operation has been carried out by the operator.
T4键用于手动换刀，它通知数控系统操作是人为的。
The PLC controls that all the operations concerned by the tool change would be done in the correct sequence and it accepts the selection of the T4 key only when the tool is changed. The tool change program is waiting in any case a further selection of the key “NC-Sta rt” in order to complete the movement of the machine.
PLC控制所有与换刀相关的操作按照正确的顺序进行，只有换刀时才接受选择T4键。换刀程序等待进一步选择“数控-开始”以完成机床的运动。
T5 key:
The T5 key serves to reset the tool magazine. If during the tool change you select the key reset it is possible that the tools would be marked as of changing tools. A tool being in this position can’t be called into the spindle and so you can’t use it for the machining.
键5用于刀库恢复。如果换刀期间按下复位键，则刀具保持标记。处于此种情况下的刀具不能被主轴重复使用，因此不能用于加工。
To avoid this condition it is suggested, after carrying the machine at the normal 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 machine may 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 machine, as it was conceived, doesn’t allow the operator to us it in automatic or semiautomatic, if at least one of the axes has been referenced (spindle excluded). This is necessary in order to avoid any automatic operation providing the referencing of the axes (i.e the automatic 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 machine is not working at full safety conditions, and so he has to be aware of which automatic operation he can or not use. 当然，操作员应明白使用该键时机床没有在最安全的条件下工作，因此操作者必须注意能否进行自动操作。
To operate the function of axis reference by-pass it is necessary to press the selector key of the axis not to be referenced together with the key 6. This last has to be released before the axis selector key, otherwise the by-pass will not activated.
要使参考点旁通，只要按住所选没有回参考点轴的按钮并同时按下键6。此外，键6必须在轴选择键释放前释放，否则通路不能被打开。
It is also possible to exclude more than one axis by operating in the same way as said above.
停止多个轴为了在另外轴上用上述同样的方法操作是可行的。
To exclude the by-pass function you have to press only the T6 key.
切断通路只要按下T6键即可。
The relevant led on shows that at least the reference of one axis has been excluded, while the led off shows that the machine is normally working.
与其相关的信号灯亮时表示至少轴上的一个参考点被切断，灯灭则表示机床正常运行。
By pressing an axis selector key it is possible recognizing if the concerned axis has been by-passed or not. In this condition the led off/on shows that the axis in not subject to by-pass, while the led flashing shows that the by-pass is active.
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 manual unclamping of the attachment. Being that a dangerous operation, both for the operator and for the integrity of the attachment we have provided that the manual unclamping takes place only by selecting it on the headstock control panel and by pressing the T7 key. This avoids that the operator could wrongly unclamps 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 unclamps all the machine axes except for the B axis of the table for which it is necessary at each control waiting for its unclamping.
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。
The relevant led ON shows the selection while the led OFF shows the deactivation.
相关的灯亮表示该选择器启动，灯灭说明切断。
T9 key:
The key “lamps test” has been provided to allow a rapid check of the different lamps, which the machine is equipped. Its function is that of switching on the lamps and the led associated to the “Customer” keys placed on the main control panel. As the functionality of the lamps shows the special conditions of the machine, their failure may confuse the operator, which is monitoring the machine itself.
“信号灯测试”键用于快速检查机床几个部位的信号灯的完整性。它的功能简单，只要打开所有的信号灯和主面板上“用户”键相关的灯。由于信号灯是用来表示机床的特殊状态，其中一盏有故障会导致操作者错误判断机床的实际状态。
This key serves in fact to check the correct operation of these indicators and it has to be always used when doubting about the interpretation of the indicator as regards to the reality. The relevant led states the selection done.
此键用于实际检查这些灯正常运行与否，并用于怀疑灯的显示和实际状态不符时。相关的信号灯仅用于表示此键已被按下。
T10 key:
For the machine safety they have been provided some interference zones among the mechanical components.
为了机床的安全，在几个机械部位中有一些干扰区。
These safety devices restrict consequently some operations of the machine. To this end it has been provided a key for the interference by-passing which functioning only in Jog mode. When this key has been selected it is necessary that the operator checks himself any possible collision between the machine and the table, or the machine and the pick-up.
