P60.XYZ200 piezo nanopositioning stage is designed with the most advanced technology and safety standards for your own safety and the correct use of the product, please observe the following points when in use.

• A change in temperature and pressure will charge the piezoelectric actuator, and the actuator will remain charged for a period of time when it is disconnected from the controller, so the operator should pay attention to when in use:
• Do not disassemble P60.XYZ200 piezo nanopositioning stage.
• Discharge P60.XYZ200 before mounting, which can be done by connecting to the controller.
• Do not unplug the wire connecting with the controller during operation.
• Before use, check whether the connection wire of the product is in good condition and whether the product and the controller are effectively grounded. During operation, strictly standardize the operation.
• Do not touch the product (up to 150V voltage) with your hand when powered on, in case of danger.
• In order to prevent damage to the product caused by improper operation, the following points should be paid attention to the following points when in use. P60.XYZ200 piezo nanopositioning stage should be used in a dust-free, oil-free and lubricant-free environment.
• As the product is designed with flexible structure, it is recommended that the load should not exceed load capacity of product. When loading, DO NOT apply torque force and DO NOT pry or twist the load surface, so as not to damage the structure. Recommended voltage range is 0~120V for long-term use and lifetime.

Product Overview

Product Introduction

• P60.XYZ200 piezo nanopositioning stage has the following advantages:

• High-performance piezo stack: P60.XYZ200 piezo nanopositioning stage is driven by a highly reliable ceramic actuator with a fully insulated structure, so its performance and service life are far better than the traditional actuator. The insulating layer can effectively prevent the piezoelectric ceramic from being damaged when exposed to moisture. Therefore, the stability of piezoelectric ceramics can be guaranteed under extreme circumstances. Compared with traditional driving mechanism, there are no transmission parts and friction. Therefore, ceramic actuator has the characteristics of no rebound, no maintenance, and no wear, etc.
  Flexible hinge structure: P60.XYZ200 piezo nanopositioning stage adopting flexible hinge mechanism has advantages of no friction, high positioning accuracy. Flexible hinge is an element not affected by static and dynamic friction, based on the elastic deformation of metal material (e.g., steel) , there is no rolling and sliding parts. Flexible unit has very high load capacity and stiffness. Hinge guide needs no maintenance and no wear and tear. Suitable for a wide range of temperatures, no lubricating oil is required.

• Strain SensorStrain sensor detects the position information by its own expansion. They are fixed in the proper position of the transmission part and measure the displacement of the moving part. This type of position measurement is made by contact and indirect measurement. So the displacement of the moving platform is measured by measuring lever, guide hinge, or piezoelectric ceramic stack.

• The sensor is connected by full bridge without drift and can accurately do the position in the nanometer range.

• The stroke of P60.XYZ200 piezo nanopositioning stage can reach 200μm per axis in XYZ.

• The flexure hinge mechanism ensures that the XYZ-dimensional motion has no coupling, and features no mechanical friction, fast response speed, high repeatable positioning accuracy, high flexibility, easy to operate, so it can meet different applications. This product can also be customized according to the needs.
  P60.XYZ200 is mainly used in biotechnology, interferometry, quality detection, optical detection, nano-positioning, microscopy and imaging, image processing and other fields.

Product Features

• Large displacement in XYZ.
• Closed-loop strain gauge sensor, high positioning accuracy.
• Mainly used in low-frequency or static applications.

Operating environment

• A clean, dustfree and non-corrosive environment
• Operating temperature: -20~80℃
• Relative humidity: <60%
• The recommended voltage range is 0~120V for long-term use and lifetime

Installation and operation

Safety checks should be carried out before installation, such as whether the connection wire is damaged or broken, whether the drive power supply is grounded, etc.
Installation and Precautions

1. Make sure the mounting surface is flat.
2. Use M6 screws to mount the P60.XYZ200 and tighten.
3. Mount a load and tighten it properly to achieve high positioning accuracy.
4. Connect P60.XYZ200’s connector to the corresponding interface of the controller according to the identification on the leads.

The connection mode of the LEMO connector is shown in the following figure.

The P60.XYZ200 mounting diagram is shown below:

Load
When mounting the load, ensure that the load quality is less than the maximum load capacity of P60.XYZ200, and try to mount the load in the center of the moving surface. The correct position to mount the load is shown below.

For the protection of the product, we do not recommend that the load is too high. If a higher load must be used, please appropriately low the position of the center of gravity of the load.
The wrong mounting way is shown in the figure below:

It is forbidden to mount the load on one side of the moving platform, which will cause serious damage to the product, as shown in the figure below.

Too long screws selected in the fastening and connection process will lead to failure of mounting or part of the bolts will be exposed, which will scratch the product and affect the motion accuracy of the product. If the bolt is too short, the connection will be weak, and it is easy to be loosened. Loosening during operation will damage the internal structure of the product.
We recommend using the connection method shown in the figure below:

Please do not connect in this way as shown below:

Notice:

• When mounting the load, tighten the load slowly. The torque should not be too large to prevent damage to the mechanism.
• Avoid stretching and bending cables.
• Use the dedicated cable provided by CoreMorrow to connect P60.XYZ200 and the controller.
• Do not connect via an extension cable casually, if you need a longer cable, please contact CoreMorrow.

Operating
Please reconfirm the following information before turning on the power:

• The operating environment meets the operating environment requirements of P60.XYZ200.
• Fixed screws must be tightened.
• After the above information is confirmed, relevant controller operations can be carried out:

1. Please read the user manual of the controller carefully before operation, and then start the controller.

2. Set the controller’s output voltage to zero first.

3. Check no abnormal phenomenon, then input voltage value (via keyboard or analog control) according to the specified input voltage range.

4. Operating normally within the rated voltage range of piezoelectric ceramics (0~120V, maximum 150V).

5. After use, please carry out a voltage reset operation.
   Please take light steps when P60.XYZ200 in operation, do not knock the product, so as not to affect the use of the product or even damage the product.

6. The resolution of the product itself is unlimited, and the resolution depends on the performance of the controller. In order to achieve better motion precision, it is recommended to use our company’s supporting controller. Please refer to the user manual of the controller for the specific operation to ensure correct operation before the relevant operation.

Notes：

• Do not remove the grounding protection during the operation. If you need to remove it temporarily, please reconnect the grounding protection before starting it again.
• The driving voltage shall not exceed the voltage range of P60.XYZ200(150V).
• If any abnormal noise or oscillation occurs during use, turn off the power immediately and check the parameter setting.
