• Piezo actuators is used as much as possible in dust-free, oil-free, lubricant-free environments
• Since the product adopts flexible structure design, it is recommended that the load not exceed the bearing capacity of the product. Pay attention to the torque when loading. Do not twist or twist the load surface to avoid damage to the structure
• When an abnormal situation occurs, the relevant part should be closed immediately
• For low voltage piezo acutator, recommended voltage 0~120V for long-term operation to extend lifetime
• For high voltage piezo acutator, recommended voltage 0~800V for long-term operation to extend lifetime
• Do not disassemble the product to avoid product damage.；
• Avoid stretching and bending the cable interface to prevent damage to the cable
• Use the dedicated cable provided by us to connect the piezo actuator and piezo controller

Product Overview

Product Introduction
Preloaded piezo actuators offer nanometer resolution with stroke up to 260μm, microsecond response time. The high internal mechanical preload force is suitable for high-load, high dynamic applications. The blocking force is up to 50,000 N, making it ideal for machine tools, active vibration insulation or adaptive mechanics. The small size and high resonant frequency of them make it ideal for applications such as scanning microscopy, laser tuning, beam deflection, patch clamp or microlithography. There are 4 types about the multiple ends: plane, sphere, internal thread, external thread.

According to the appearance, it could be divided into cylindrical, and external thread shapes

Working principle

Product Features
Preloaded piezo actuators are superior to piezo stacks, mainly in the following aspects:

• Easy to installing and fixing
• Piezo stacks are not easily damaged
• High closed loop accuracy
• Could withstand axial tensile and shear forces
• Resistance to electric field interference

Motion direction
Motion direction is shown in .

Operating environment

• Operating temperature: -20~80℃
• Environment free of dust, clean, and non-corrosive substances
• Relative humidity: <60%
• Low voltage piezo actuator recommended voltage between 0 and 120V for long-term and high-reliability operation and high voltage piezo actuator recommended 0~800V.

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.

Installation and connection

Piezo actuator installation steps are as follows:

1. Clean the installation plane before fixing the installation
2. Connect the load, the load should not exceed the max load that the piezo actuator could bear. Pay attention to the clamping surface with a wrench when installing. Please refer to the size of each actuator to select the appropriate connection form.
3. Mount the piezo actuator on the measuring platform or fix it on the measuring plane through the optical platform adapter. Please select the appropriate screws according to the structural dimension drawing for fixed installation. Pay attention to the clamping surface with the wrench when installing. Torque is generated during installation to avoid damage to piezo actuator
4. Connect the piezo actuator to the controller
5. If you have any questions, please contact us.。

LEMO connector wiring is as shown below:

• If the installation plane is not shown in the above figure, other directions or mounting apertures are required, we also could provide corresponding adapters, as shown below:

Fixed and loaded
In order to prevent piezo actuator being damaged during use, the following points need to be noted:

• Please do not drive piezo actuators beyond the voltage range in parameter.
• Do not drop piezo actuator and avoid any form of mechanical impact.
• Preload piezo actuators could withstand tensile force (not the contraction of the piezo actuator), but could not withstand shear, torque and bending moments. These conditions may cause damage to the piezo ceramic inside the actuator. Shear, torque and bending moments could be removed by ball head or suitable guiding mechanism.

Operating
Please confirm the following information before starting the power supply:

• The environment meets the requirements of the piezo actuator working environment;
• The fixing screws must be tightened; The above information is determined to perform controller related operations:
  1. Please carefully read the piezo controller user manual selected before operating, and then start the controller.
  2. Set the piezo controller to zero;
  3. fter checking for no abnormalities, input voltage values according to requirements (keyboard or analog control); Please set the piezo controller to zero after used； Please do not touch the product during the operation, avoid affecting the actuator performance or even damage the actuator. The resolution of piezo ceramic is not limited. It depends on the performance of piezo controller. In order to better achieve the motion accuracy, it is recommended to use CoreMorrow piezo controller. For the operation of piezo controller, please refer to piezo controller usual manual.

Transportation and inspection

Transportation
Piezo actuator is packed in carton. The transportation is carried out under the condition of packaging. This product can be transported by various means of transportation under normal conditions. During transportation, it should avoid direct rain and snow, avoid contact with corrosive substances, and avoid strong collision, try to avoid improper behavior such as squeezing, irregular placement.

Unpacking inspection

• Please handle gently when unpacking to avoid permanent damage to the platform caused by bumps;
• Please do not use heavy tools or use rough methods to open them;
• Do not discard all packaging materials for return shipments.

Maintenance and processing

Problem Processing
If the user has problems that could not be solved. Please record the fault situation and contact with us. The professional technical engineer would help solve the problem. Problems caused by improper operation are not covered by the warranty; CoreMorrow is not responsible for any problems caused by dismantling the peizo actuator without permission.

Daily maintenance
If the actuator is not used for a long time, please store it in an room environment with no dust, good ventilation, clean and non-corrosive substances. Please do not loosen the screws on the actuator structure, avoiding to affect the accuracy of the actuator.

Daily cleaning:
Please disconnect the actuator to the controller, then clean the surface of it. When cleaning, first wipe a small amount of detergent with a towel and gently wipe the surface of the actuator, then wash it with alcohol. Please do not use ultrasonic waves for cleaning. When cleaning the surface, try not to pick up the product. If it is necessary to pick up, please place a sponge under the actuator for protection, the actuator should not be too high from the sponge to prevent the actuator from falling off.
