⚠️ Warning: 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 this when in use.

• Do not disassemble S38 Piezo Tip/Tilt Platform.
• Discharge S38 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 power on, in case of danger.

❗ Attention: In order to prevent damage to the product caused by improper operation, the following points should be paid attention to when in use.

• S38 Piezo Tip/Tilt Platform should be used in a dust-free, oil-free, and lubricant-free environment.
• As the product is designed with a flexible structure, it is recommended that the load should not exceed the load capacity of the 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.

• Do not connect via an extension cable casually; if you need a longer cable, please contact CoreMorrow.

3. Product Overview

3.1 Product Introduction

S38 Piezo Tip/Tilt Platform has the following advantages:

High performance piezo stack:

S38 Piezo Tip/Tilt Platform 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 mechanisms, there are no transmission parts and friction. Therefore, the ceramic actuator has the characteristics of no rebound, no maintenance, and no wear, etc.

Flexible hinge structure:

S38 Piezo Tip/Tilt Platform adopting a flexible hinge mechanism has advantages of no friction and high positioning accuracy. The flexible hinge is an element not affected by static and dynamic friction, based on the elastic deformation of metal material (e.g., steel), with no rolling and sliding parts. The flexible unit has very high load capacity and stiffness. The hinge guide needs no maintenance and no wear and tear. It is suitable for a wide range of temperatures, and no lubricating oil is required.

Strain sensor

Strain sensors detect position information by their 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 S38 piezo tip tilt platform is a θx, θy two-dimensional deflection piezo fast steering mirror. It is equipped with a lens mounting cap and is small in size and easy to integrate. It can be integrated into a cage structure with a right-angle adapter.

3.2 Product Features

• θx, θy tilt
• Tilt stroke up to 2.4mrad
• Optional closed loop sensor
• Optional right-angle adapter structure

3.3 Principle

The piezo control principle is as follows:

The piezo tilt stage (two-axis motion) is based on parallel kinematic design with coplanar axis and moving platform. Four piezo actuators are placed at a 90° angle interval, with paired differential control distribution. Two pairs of differentially driven actuators provide the highest achievable angular stability over a wide temperature range. Its tilt motion is achieved by two pairs of piezo actuators in a push-pull motion, controlled by a bridge connection circuit.

3.4 Motion Direction

4. 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

5. Installation and operation

Before installation, first check the safety, such as whether the cable is damaged or broken, and whether the power supply has grounding protection.

5.1 Installation and connection

S38 installation diagram is as follows:

1. Before attaching the mirror, please clean the mirror and motion surface. After the mirror is glued, please wait for a period of time until the adhesive solidifies.
2. You need to use M2 screws to mount the S38, and you can also adopt an adapter. CoreMorrow has many adapters for your choice, as shown in the diagrams. Before mounting, please clean the mounting surface and adapter.
3. Mount S38 on the mounting surface directly or by an adapter. Please contact CoreMorrow if you don't mount it with a stand, such as lean or lateral mounting.

Mounting notes:

• Do not knock the moving part of the product to prevent flexure hinge deformation affecting the movement accuracy, or even damage the product.
• Do not drop mirror adhesive into the gap at the moving end, and do not have other objects to hinder the movement, so as not to affect the accuracy or damage the equipment.

Please select appropriate screws for the mounting connection to prevent the mounting from being not firm and the mirror falling off, causing permanent damage.

Please pay attention to standard operation during the whole mounting and operation process. Users should carry out relevant operation under the guidance of professionals.

5.2 Load

When installing the load, ensure that the load mass is less than the max load of S38, and install the load as much as possible at the center of the moving surface.

The correct placement of the load is shown below:

For protection, CoreMorrow does not recommend the load to be too high. If a higher load is used, please reduce the position center of the load gravity. The error placement method is as follows:

It is forbidden to load the load on one side of the piezo stage, which would cause serious damage to the product, as shown in the following figure:

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 S38 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:

• S38 has been grounded protection.
• Operating environment meets the operating requirements of S38.
• 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 for any abnormal phenomenon, then input voltage value (via keyboard or analog control) according to the specified input voltage range.
4. Operate normally within the rated voltage range of piezo products.
5. After use, please carry out voltage reset operation.

Please take light steps when S38 is 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 S38, it is recommended to use CoreMorrow's supporting controller. Please refer to the user manual of the controller for the specific operation to ensure correct operation before relevant operation.

Notice:

• Do not remove the grounding protection during 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 S38.
• If any abnormal noise or oscillation occurs during use, turn off the power immediately and check the parameter setting.
