Safety Guide
S20 piezo rotation 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 energized 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 S20 piezo rotation stage.
- Discharge S20 before installation, which can be done by connecting to the controller.
- Do not unplug the wire connecting with 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 power 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 when in use.
- S20 piezo rotation stage is 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.
- Do not disassemble the product to avoid damage.
- Avoid stretching and bending the cable interface to prevent damage to the cable. Use the dedicated cable provided by CoreMorrow to connect S20 piezo rotation stage to controller.
- Do not connect via an extension cable casually, if you need a longer cable, please contact CoreMorrow.
Product Overview
S20 piezo rotation stage has the following advantages:
-
High performance piezo stack:
S20 piezo rotation 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:
S20 piezo rotation stage adopts 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 sensor
Strain 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 a full bridge, no drift, and can be precisely positioned in the nanometer range.
The S20 can run up to 0.55mrad, and features 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.
S20 is mainly used in biotechnology, interferometry, quality detection, optical detection, nanometer positioning, microscopy and imaging, image processing and other fields, with a very good development prospect.
Product Features
- Good dynamic characteristics, fast response speed.
- Closed loop strain gauge sensor, high positioning accuracy.
- Can be used at high frequencies.
Motion Direction
Operating environment
- Operating temperature: -20~80℃
- Environment free of dust, clean, and non-corrosive substances
- Relative humidity: <60%
- Recommended voltage between 0 and 120V for long-term and high-reliability operation.
Installation and operation
Installation and Precautions
- Ensure that the installation plane is relatively flat;
- Mount M3 on the mounting surface directly and tighten it;
- Mounting the load and tighten it properly to ensure the positioning accuracy;
- Connect the S20 connector with the corresponding controller according to the identification at the connector;
The wiring mode of LEMO connector is shown as below:
S20 Installation diagram is as follows:
Load
When mounting the load, ensure that the load quality is less than the maximum
load capacity of S20, 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 high 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.
Excessive length of screws selected in the fastening and connecting process
will lead to failure in installation or leakage of bolts, which will expose
the product and scratch the product, affecting the motion accuracy of the
product. Short bolts will lead to insufficient compactness of the connection
and easy looseness, which will damage the internal structure of the product
during operation.
We recommend using the connection as shown 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 S20 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 S20 has been grounded.
- The operating environment meets the operating environment requirements of S20.
- Fixed screws must be tightened.
After the above information is confirmed, relevant controller operations can be carried out:
- Please read the user manual of the controller carefully before operation, and then start the controller.
- Set the controller’ output voltage to zero first.
- Check no abnormal phenomenon, then input voltage value (via keyboard or analog control) according to specified input voltage range.
- Operating normally within the rated voltage range of piezoelectric ceramics (0~120V, maximum 150V).
- After use, please carry out voltage reset operation.
Please take light steps when S20 in operation, do not knock the product, so as not to affect the use of the product or even damage the product.
In order to achieve better motion precision of S20, 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 relevant operation.
Notice:
- The driving voltage shall not exceed the voltage range of S20.
- If any abnormal noise or oscillation occurs during use, turn off the power immediately and check the parameter setting.
