图2 接口板
操作
我们的滑动式多孔安装座和接口板非常坚稳，足以应对一般操作。图1中标记出了ELL9K套件的关键组成部分，图2为接口板的图片。为了确保运行可靠，与电机接触的表面不要沾染油、污垢和灰尘。拿取双孔或四孔安装座时无需戴手套，但是要避免触摸与电机接触的表面，防止其沾染指纹上的油污。如需清洗与电机接触的表面，可以使用沾有异丙醇或矿物溶剂(石油溶剂)的KW32或其他超低绒毛的纸擦拭。但是不要使用丙酮，因为这种溶剂会破坏安装座的塑料边缘。
这些安装座的开放式框架结构可耐受高达8 kV的静电放电，但应采取ESD预防措施，因为静电放电会可能产生引起位移台意外移动的电气信号。避免让结构PCB承受超过500 g的负载。如果过载，PCB可能会弯折，这会损害安装座的性能。
安装
在适当条件下操作滑动式多孔安装座，使滑块能在垂直(正置)或水平面(放平)移动。当竖直安装滑动式安装座时，滑动板就会左右移动，而不是上下移动，这是由于重力效应显著减少了可移动的最大负载。竖直安装时，电机可安装在滑动板的上方或者下方；但是，建议将电机安装在滑动板的下方，如图3-7所示，这样可以最大程度地减少在工作过程中灰尘或微粒落到滑动板中光学元件表面的几率。当安装座水平安装时，要保证安装不会使PCB弯曲。总之，要保证滑动式多孔安装座的移动部分不会受到干扰。
安装滑动式安装座的方法有几种。下方出售的ELLA1接杆安装转接件可以直接安装在安装座PCB的背面。如图3所示，然后可以利用转接件将安装座安装到Ø1/2英寸接杆。ELLA1的尺寸紧凑，以便将多个安装座前后放置，同时最大程度地减少安装座之间的间距，如下图所示。该转接件还可以与Thorlabs的30 mm笼式系统组件和/或SM1螺纹组件集成(比如透镜套管)。另外，也可以单独使用30 mm笼式系统组件安装安装座。如图4中示例，使用了CP33笼板、四根ER1支杆和Ø1/2英寸接杆和接杆支架来安装和支撑组装的ELL6K。
负载
150 g的最大总负载规格是指安装在滑动板上的负载重量，并不包括安装座的重量。例如，无负载ELL6安装座重量约为22 g，安装光学元件所允许的最大重量为150 g；安装座与光学元件的最大总重量为172 g。两种安装座都兼容30 mm笼式系统组件。
供电
使用接口板
虽然需要超声电压信号来操作电机，但可通过给接口板施加直流电压信号来给安装座供电。接口板上的电子装置可将施加的直流信号转变为以指定谐振频率振荡的正弦信号，从而实现这种可能。
ELL6包含一个电机，ELL12和ELL9包含两个电机。由于ELL6单个电机的功率要求较低，因此可以通过接口板的Micro-B USB接头给ELL6供电。ELL6K套件中不附带5 V电源。两个电机的操作需要5 V电源，所以ELL12K和ELL9K套件中附带了一个这样的电源。
使用接口板上Micro-B USB接头给ELL6供电的优势在于可以通过计算机同时控制并给安装座供电。笔记本电脑可以提供使ELL6滑动式双孔安装座切换位置的电流强度；但是，有些笔记本无法提供寻找最佳谐振频率所需的1.2 A电流，这点在下面的谐振频率部分有提到。在这种情况下，为了寻找最佳谐振频率，就必须使用其他可以供应所需电流强度的电源，以补充笔记本提供的功率。
装置中包含ELL12和ELL9和接口板时，可以通过5 VDC电源插座供电。由于Micro-B USB接头无法提供驱动两个电机的功率，因此该接头只适合用于安装座的计算机控制。
不使用接口板
当这写安装座集成到没有接口板的应用中时，使用Picoflex接头上的引脚实现与电源的连接。该接头的引脚图包含在引脚图标签中，关于滑动式安装座的功率和寻址分别在手册和通信协议手册中有给出。
电机的工作
Elliptec电机能够移动滑动板，从而切换光学元件的位置。移动方向由驱动电机中压电元件的超声频率决定。对于每个电机，都有一个超声谐振频率使滑动板向前移动，还有一个超声谐振频率使滑动板向后移动。当电机以它的一个谐振频率工作时，会使电机的顶端以一个紧凑的顺时针椭圆路径不断循环运动，而当电机在它的其他谐振频率下工作时，电机的顶端以相同的路径按逆时针方向循环。两个谐振频率在100 kHz左右，电机顶端的总位移与其驱动的机械负载和施加给压电元件的电压具有函数关系。在没有负载时，以一种谐振频率在5 V的最大驱动电压下，电机顶端追迹椭圆路径的扩展和收缩在几微米之内。更多信息，请查看Elliptec®电机 标签以及描述电机工作的视频。
谐振频率
通电时，出厂默认设置会指令安装座搜索可以产生最佳性能的谐振频率。在此过程中，安装座会在前后位置间移动。该校准过程结束时，安装座处于向后的位置。如果启动时不需要这个运动，可以在通电时利用串行端口预置频率，便可不用执行该校准程序。任何时候都可以进行最佳谐振频率的新搜索；为了保持最佳性能，建议负载和/或环境温度发生变化后执行新搜索。请看手册的Section 4.4了解详情。
操作滑动式安装座
请注意，我们的滑动式多孔安装座不适合持续工作。一般使用过程中，我们建议在占空比为40％以下时进行操作，占空比高于60%的操作应该限制在几秒钟之内。
按下接口板上的按钮，通过Elliptec®软件包(可下载)经计算机可以控制安装座滑动板的移动，这也可以通过给滑动板上的数字线路发送简单的信号来实现。恒定的驱动功率产生线性速度曲线，使电机能够在几微秒内加速和减速。
通过Elliptec软件连接安装座时，可以将该接口板当作配件使用；所有因按压接口板上的按钮导致滑动板位置的变化都会记录在软件上，连接接口板时，软件也可独立控制滑动板。图2中可以看到接口板上的按钮。
通可以使用ELLB总线分配器或将多个接头接到一根带状电缆上以控制多个Elliptec设备。一个总线分配器最多可以连接四个Elliptec装置。如果总线以菊花链连接，则最多可以连接16个装置。可以通过以下三种方式控制此总线：通过接口板(包含在以下套件中)连接至运行Elliptec软件的PC、连接到Arduino®或Raspberry Pi®板，或通过接头引脚接线到用户提供的控制板上。 另外，一条带状电缆最多可以接16个装置。然后可以通过接口板同时控制这些装置，或者可以通过Elliptec软件选择性地控制。有关自定义连接时如何分配引脚请查看引脚图标签，了解如何将多个装置接到带状电缆上请查看手册。通信协议手册里面描述了使用软件单独控制每个连接的设备的方法。软件标签中包含下载软件和附带文档的链接。
图5 - 7以及概述标签中的视频展现了ELL6滑动式双孔安装座使用接口板工作的过程。按下接口板上标有"FW"的按钮，如图6所示，滑动安装座就移向前面的位置。按下接口板上标有"BW"的按钮，滑动安装座就回到了初始位置。
使用接口板控制ELL12或ELL9四孔安装座上滑动板的位置时，也可以使用JOG按钮。如果滑动板面朝前，在竖直方向，电机在安装座下方，按住JOG按钮并按下FW按钮，将滑动板移动到观察者的右侧。按住JOG按钮并按下BW按钮，将滑动板移动到观察者的左侧。换句话说，参考规格标签底部的图纸，前者增加了滑动板的位置，后者减少了滑动板的位置。

Elliptec压电谐振电机
Elliptec®压电谐振电机
Thorlabs的Elliptec®压电谐振电机(如右图所示)重量很轻，只有1.2 g，且结构紧凑：其外壳除弹簧之外的尺寸为8 mm x 4 mm x 20 mm。
电机组件
电机组件如最右图所示。压电元件压接到铝制谐振器中，其经过精心设计和精密加工，可以使顶端进行所需的椭圆运动，并良好地接合被驱动的模块。弹簧的自由端连接谐振器外壳。焊接到压电元件顶部和底部的电线可以传送电压信号，使压电元件以超声频率振动。
将电机内置于系统时，弹簧的开环被螺栓连接到一个坚固的表面，该表面相对于被驱动的物体静止，而谐振器的顶端会接触该物体。弹簧的作用是为了保持谐振器顶端与被驱动的物体稳定接触。运动方向由驱动压电元件的谐振频率决定。
椭圆运动以及与传统电机的比较
Elliptec电机可以迅速而准确地定位位移台和安装座，而看上去似乎并未移动。实际上，它以超声频率进行微观运动，但肉眼看不到。
以两种谐振频率中的任一一种频率驱动电机，便可使其工作。将以超声频率振荡的电压信号施加到压电芯片时，压电芯片会以该驱动信号的频率扩展，幅度小于1微米，然后缩回原始尺寸。芯片尺寸这种快速的周期性变化可以使铝制谐振器外壳振动。当以外壳的一种谐振频率振动时，电机顶端会产生推动运动。而以另一种谐振频率振动时，则会产生拉动运动。
如视频所示，电机以谐振频率工作时，该电机顶端在空间中以椭圆路径进行推拉运动。所选的谐振频率控制周期运动的方向。电机的顶端扩展时，运动路径为椭圆路径的一半，收缩时，运动路径则为椭圆路径的另一半。电机推动所驱动的物体时，电机的顶端接触物体，同时顶端扩展；而顶端收缩时，两者不接触。当电机拉动被驱动的物体以反方向运动时，情况也是如此。电机顶端的总位移与其驱动的机械负载和施加在压电元件上的电压具有函数关系。当峰值驱动电压为5 V时，最大位移最多可以达到几微米。
该压电谐振电机与直流或电磁步进电机在许多方面都很相似，但它没有这些传统电机的一些缺点。比如，传统的电磁电机必须克服惯性延迟才能停止工作，而高动态的Elliptec电机在几微秒内就可以直接停止。由于它没有齿轮装置，因而不会有反冲现象。而且，它也没有磁铁，可以兼容对电磁干扰敏感的环境。被驱动的物体会连续而流畅地运动。由于电机的顶端必须与被驱动的物体接触以使其运动，电机具有固有摩擦制动的安全特性。与塑料表面接触时，电机几乎会无声地工作。
对于OEM应用，可以低成本批量制造这种电机，它可以由便宜的模拟电子元件驱动，且不需要微处理器和软件；但它可以与之兼容。

I purchased a couple of rotation mounts (ELL14K and ELL18) for use with a high power femtosecond laser. I would like to have a protective cage to avoid damaging the electronic components and scattering of the laser. Do you have an example of a 3D printable design for this purpose?

(posted 2024-01-03 06:22:38.0) Thank you for your feedback and I am sorry to hear this. Usually this can be fixed by performing a frequency search, as operating too far from this optimum frequency can cause it to move slowly or not reach the desired location. The other thing I would suggest is to clean the rail with IPA as this can be another reason it does not reach the desired location. I will reach out to you directly to further help troubleshoot this with you. Fabian C

(posted 2023-11-13 04:45:37.0) Response from Daniel at Thorlabs. This is caused by the motor not reaching the correct position or not being able to sense the starting position.

(posted 2023-08-04 12:43:47.94) In the ELLB's manual it could be useful to note that the USB RX/TX pins work as UART. Many things are quite obvious in hindsight, but when having issues (for example since the board is not responding any command when no motor is connected or when receiving garbage from a floating), that confirmation would be useful as a confirmation.
In addition, it is noteworthy, that TX/RX is reversed compared to common labelling. Usually, TX of one device gets connected to RX of the other device. On the distributor port, one has to connect the microcontroller's TX pin to the distributor board's TX pin. The naming gets slightly inconsistent since the board's TX pin is internally connected to the RX pin of the MOLEX connector.
Since it's not only the manual but also the PCB where the TX/RX labelling is printed, I would at least clearly specify the mix up it in the manual.
Best,

I am using your ELL6K in a box that also houses an APD. When I connect the ELL6K to the USB port (providing power to the device), I have a significant increase in the APD's count rate? Most likely the ELL6K is using optical position feedback from an LED or something. Can you specify the wavelength?
Kind regards do'neill
(posted 2023-06-21 06:55:39.0) Response from Daniel at Thorlabs. The home sensor of the device uses a 950nm led which can leak light. This should be taken into consideration for environments that are sensitive to light sources at and around this wavelength. Kai M

We purchased ELL9K and installed in our single molecule microscope. Recently, we found out that ELL9 (not the interface board) emits some kind of light so that it was giving a high amount of background to our camera images. By adding short-pass 750 filter in front of camera, we could block the background signal completely. Do you know if there is any LED or a light source in IR on ELL9?
I just wanted to know if you are aware of this or if it is specified somewhere. Thank you.

(posted 2023-01-20 05:35:24.0) Thank you for your enquiry. All of our ELLx devices use a photo interrupter for the homing and encoder, it emits at 950 nm and the detector part is sensitive from 700 to 1200 nm. Due to this light source, applications that are very sensitive to 950 nm light should not use the ELLx devices or should take precautions to protect their application from this light. Some ELL devices may also struggle to home if they are exposed to a large amount of light in the 700-1200 nm range. user

(posted 2022-12-16 10:24:26.0) Response from Charles at Thorlabs: Thank you for your query. These sensors are small IR LEDs paired with photodiodes. When paddles on the back of the moving world block the light from hitting the photodiode, the position of the stage is updated. Sensor errors are usually the result of ambient light/laser light getting into the photodiode, dust obscuring the photodiode, or a paddle not sufficiently blocking the light. I will reach out to you to help resolve this. Lavonne Dettmers

ELL9 warns against having the component plugged in USB when a computer isn't fully on. What of a USB hub ? Can it be plugged as long as the hub is powered ?

(posted 2021-11-01 11:42:33.0) Response from Charles at Thorlabs: Thank you for your query.
This was an issue with old versions of the USB remote interface board. Version 2 onwards should not have this issue. The issue is backfeeding of current to the USB hub. The way the USB has been implemented within the computer's USB HUB will determine whether or not it is suitable and our engineers found that even within the same laptop you could have some USB ports which are OK and will not be affected and others which are not OK and could have this issue. If using the old board then the only way to be sure is to either power the PC first or to desolder the transistor (labelled Q1 on the old boards). You cannot fix this with an external HUB. user

(posted 2021-08-17 04:28:11.31) I think it should be stated more prominently (maybe on the main product page and not only in footnote (c) on the specs page) that the ELL9 can only be operated horizontally. When mounted on, e.g., a motorized rotation mount (which might be something a lot of customers think of as a possible application scenario), the ELL9 only moves correctly when aligned horizontally. In vertical orientation (rotation stage turned by 90 degrees), the motors are to weak to move even the weight of the slider alone, i.e., without any optics attached. Even though this might be obvious, it might still be a good idea to put a comment on the webpage.
In our case, we found a quick workaround, always turning the rotation mount before changing the ELL9 position, so that the slider motion always occurs in the horizontal direction. But other customers may want to use the slider at arbitrary rotation angles, which won't work out.
Apart from that, these are awesome devices. cwright
(posted 2021-08-18 05:29:28.0) Response from Charles at Thorlabs: Thank you for your feedback. We will consider adding a clarifying note to the web presentation. The behaviour in this orientation is more due to the nature of the motor than its strength. The motor's tip follows an elliptical path when active and in order to advance the moving world it must leave contact with this moving world for a short time each repetition. When used with the slider orientated vertically the effect of gravity would oppose the intended motion of the slider and cause slipping. This motion can be seen in more detail in the video on the following page:

The resonant motor will produce auto-fluorescence after plugging in the USB, about 100kcounts/s, which is detected by APD (Single Photon Counter), which is very fatal for microscopic fluorescence testing and will cover up when scanning imaging. For weak light signals, a single nanoparticle is usually only 15k-40kcounts/s. James Grieve

(posted 2019-04-03 04:07:51.447) Hi Thorlabs service Team,
Nice little product. I am using the serial commands in python (pyserial) to access the four-position slider.
The connection is always successful and "0in" always returns the right output. Occasionally however, a "0ma00000000" is unsuccessful and returns a "signal error" - "0GS0A". Once it occurs, I can't move the stage anymore, even when I disconnect with python and connect with ELLO. (0ma attempts always return 0GS0A) Unplugging the stage resolves this issue but do you have any advice on how I could prevent this from happening?
Note: This never happened so far with the ELLO_DLL in python but I would prefer serial commands to keep the script more versatile. user
(posted 2019-04-05 07:13:29.0) Response from Arunthathi at Thorlabs: Thanks for your query. The encoder error (0x0A) returned is a discrepancy between number of count position and requested position. It is generally a mechanical issue: vibration, moving load, stage moved or stopped by hand.
It is recommended to use HOME instead of “ma” to go to the 0 position.
Home resumes the unit from error (caused by vibration) as it resets the encoder to a known absolute 0 position.
If the issue still persists please contact your local tech support team directly for further assistance. Julien PROUST

(posted 2018-11-06 04:33:55.0) Response from Radu and Fumi at Thorlabs: この度はお問合せいただきありがとうございました。ご要望をファームウエア開発チームに伝え確認いたしました。"ma"コマンドや"mr"コマンドはELL9で使用することは自体は可能です。ただし、決められた４つのスライダーポジションに移動できるだけであり、精密な移動はできません。これは、他のElliptec製ステージと異なり、ELL9がエンコーダを搭載していないためであり、大変恐れ入りますがファームウエアの改造のみでは実現ができません。ただ、所定の時間に対してスムースに移動するようコマンドを送ることは可能です。そのようなコマンドに対するご質問や"ma"コマンドに対する応答についてのご質問がございましたら、弊社の日本オフィスsales@thorlabs.jpにご連絡くださいませ。
Translation:
Feedback: I want to finely move the hole positions with ELL9K, but it seems that the 'ma' (move absolute) command can not be used. I'd like for the stage to change such that we can use the 'ma' command.
Response: Thank you for your feedback. I have relayed it to the developers of Elliptec's firmware who will take it into account when planning for future releases. The 'ma' and 'mr' commands can be used on ELL9, but only to switch between the 4 slider positions. Unfortunately, we can't modify this stage's firmware in order to allow these commands to be used for fine translations. This is because ELL9, as opposed to the other Elliptec stages, lacks an encoder. With that being said, we could add a similar command that would allow one to translate the stage for a given period of time. If your stage is not responding to the 'ma' or 'mr' commands, please contact our Japanese office at sales@thorlabs.jp. lvjing

(posted 2018-03-29 14:55:49.94) Is it possible to turn off the LEDs in the interface board?
I'm using this slider to move ND filters and my optical setup is enclosed in a light tight box, because I need to perform measurement at very low light. The flat cable between the interface board and the slider is too short so I have to keep the interface board inside the light controlled box, but the light intensity of the LED on the board is not at all negligible. At the moment I'm covering the LED with black tape, but it's definitely not enough and not very nice.
I couldn't find anything about it in the documentation. It'd be great if didn't have to replace the flat cable with a longer one.
Thanks bhallewell
(posted 2018-04-05 07:19:20.0) Response from Ben at Thorlabs: Thank you for your feedback. There isn't a programming solution to turn off the LED however you should have access to remove the LED or alternatively short the LED with a wire. user

(posted 2018-02-15 22:01:57.177) Can one mount a ME1-P01 in one position of the ELL6, as a flip mirror alternative? Thanks! bhallewell
(posted 2018-02-23 10:55:22.0) Response from Ben at Thorlabs: You will be able to mount this optic through use of our SM1L03 SM1 Lens tube, which includes an SM1RR retaining ring to secure the optic in the lens tube. The optic seated in the lens tube can then be threaded into the ELL6 mount. The total load that the slider can actuate is 0.150 kg. user
(posted 2017-10-25 15:33:18.65) Could the ELL6 be used in a medium vacuum (>10^-2mbar) environment? Thank you very much. bwood
(posted 2017-10-30 05:06:50.0) Response from Ben at Thorlabs: Thank you for your feedback. While in principle the Elliptec motor technology will work in a vacuum, the stock ELL6 slider contains several components which will outgas, so it may not be suitable for your application. If you would like to pursue this further, I would suggest contacting your local tech support office, to discuss your application in more detail. nhuffman
(posted 2017-07-25 10:20:39.697) Are there any 32bit libraries for the Eliptec software available for 64bit Windows like are available for the APT and Kinesis software? I need to interface with 32bit MATLAB on a 64bit machine. bwood
(posted 2017-07-26 09:27:16.0) Response from Ben at Thorlabs: Thank you for your question. Unlike Kinesis compatible devices, our Elliptec devices are controlled solely through serial commands (directly or through our Elliptec System Software). You should be able to configure MatLab to communicate through these serial commands however. You can find the serial communications protocol on the Elliptec software webpage. bjorn.fjelddahl

The ELL6 is made for 2 filters
Is it possible to add two more filters to a total of 4?
Best regards,

(posted 2016-11-04 16:04:37.99) Do the top two threaded hole have clearance from the sliding portion to attach 30 cage posts on each side? i.e. can you stack multiples of these? bhallewell
(posted 2016-11-09 09:39:00.0) Response from Ben at Thorlabs: Thank you for your question here. Checking our web models, there is not enough clearance for an ER 30mm cage rod system to mate with the PCB from both sides, this is a 4-40 hole which can only be accessed from the rear side. This is one of our off-the-shelf solutions & is limited in customisation however for OEM opportunities we may be able to go beyond this. I will contact you directly to start a discussion. |
