3.1 Product Introduction

P87 Amplified Piezo Actuator has the following advantages:
High performance piezo stack:
P87 Amplified Piezo Actuator 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:
P87 Amplified Piezo Actuator 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 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.

P87 Amplified Piezo Actuator can travel up to 38μm, with small size, no mechanical friction, fast response speed, high repeatable positioning accuracy. This product can also be customized according to the needs, with high flexibility, easy to operate, to meet different applications.
P87 is mainly used in biotechnology, interferometry, quality detection, optical detection, nanometer positioning, microscopy and imaging, image processing and other fields.

In order to prevent damage to the product caused by improper operation, the following points should be paid attention to when in use. P87 Amplified Piezo Actuator should be used in a dust-free, oil-free and lubricantfree 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 P87 Amplified Piezo Actuator.
Do not connect via an extension cable casually, if you need a longer cable, please contact CoreMorrow.

5.1 Installation and Precautions

1.  Make sure the mounting surface is flat.
2.  Use M2.5 screws to mount the P87 and tighten.
3. Mount a load and tighten it properly to achieve high positioning accuracy.
4.  Connect P87’s connector to the corresponding interface of the controller according to the identification on the leads.

When screwing M3 screws with one hand, in order to avoid deformation of the mechanism or unnecessary damage, it is recommended to fix the actuator with the other hand

Fig.2 P87 Installation diagram

5.2 Load

When mounting the load, ensure that the load quality is less than the maximum load capacity of P87, and try to mount the load in the center of the moving surface.
The correct position to mount the load is shown below:

FIG.3 The load is applied to the center of the moving surface
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:

4 Try not to let the position of the center of gravity far exceed the active platform
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.

FIG.5 Do not mount long loads on one side of the platform

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 P87 and the controller.
• Do not connect via an extension cable casually, if you need a longer cable, please contact CoreMorrow.

5.3 Operating

• Please reconfirm the following information before turning on the power:
• The operating environment meets the operating environment requirements of P87.
• 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’ output voltage to zero first.
3. Check no abnormal phenomenon, then input voltage value (via keyboard or analog control) according to 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 voltage reset operation.

Please take light steps when P87 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 P87, 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

Notes：

The driving voltage shall not exceed the voltage range of P87.
If any abnormal noise or oscillation occurs during use, turn off the power immediately and check the parameter setting.
