Safety Guide

The amplified piezo actuator is designed with advanced technology and safety standards, for safety and proper use of the product, please pay attention to following points when using:

**** Temperature changed and pressure will charge the piezo actuator. Piezo actuator will remain charged for a period of time disconnected from the controller, so the operator should pay attention when using it:

• Do not disassemble the amplified piezo actuator.
• Discharge the amplified piezo actuator before installation, it could be achieved by connecting to the controller.
• Do not pull out the controller during operation.
• Before using, please check whether the connecting wire of the product is in good condition, whether the product and the controller are effectively protected from grounding,  in case of danger, please strictly regulate the operation during operation, do not touch it (up to 150V voltage) after power on.

**** In order to prevent damage to the product caused by improper operation, please pay attention to following points when using:

• The amplified piezo actuator 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.
• Recommended voltage 0~120V 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.
• Please use the dedicated cable provided by us to connect the piezo actuator and piezo controller.
• Please do not use cable extension wire, if need longer cable, please contact us.

Product Overview

3.1 Product Introduction
The amplified piezo actuator has the following advantages:

• High performance piezo stack:
  The amplified piezo actuator is driven by high-performance piezo stack. The piezo actuator is fully insulated, so its performance and service life are far superior to those  of conventional actuator. The insulating layer could effectively prevent the piezo stack from being damaged by moisture. The stability of piezo stack could be ensured  under extreme conditions. The piezo actuator has the characteristics of no rebound, no wear.

• Flexible hinge structure:
  Amplified piezo actuator adopts flexible hinge mechanism, which has the advantages of no friction and high positioning accuracy. The flexible hinge is a component that  is not affected by static and dynamic friction. It is based on the elastic deformation of solid (such as steel) and has no rolling and sliding parts. With high stiffness  and load carrying capacity, the hinge guides are maintenance-free and wear-free. Suitable for a wide range of temperatures without the need for lubricants.

• 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

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

1. Ensure that the installation plane is flat;
2. Secure the piezo actuator with M2.5 screws and tighten;
3. Install the load and tighten properly to ensure positioning accuracy;
4. Connect the cable to the corresponding interface of the controller according to the connector head;

Figure2. Connection diagram

Note: do not reverse the positive and negative electrode.
Amplified piezo actuator installation diagram is as follows:

Figure3. Amplified piezo actuator installation diagram

5.2 Load
When installing the load, ensure that the load mass is less than the max load of the amplified piezo actuator, and install the load as much as possible at the center of the moving surface.
The correct placement of the load is shown below:

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

For protection, we don’t recommend the load is too high. If it is used a higher load, please reduce the position center of the load gravity. The error placement method is as follows:

Figure6. Try not to let the load center of gravity exceed the actuator

The bottom fixing screws and load fixing screws should not touch the piezo stack. The wrong fixing methods are as follows:

Figure7. Fixing screw is too long to damage the piezo stack

If the screws used in tightening and connecting are too long, the screws will not be installed or some of screws will leak out, which will scratch the actuator and affect the motion accuracy. If the screws are too short, the connection will not be compact and easy to loosen. Looseness could damage the internal structure of the actuator.
We recommend using the connection method shown below:

Please do not connect as shown below:

Note :

• Slowly tighten the load when installing it, and the torque should not be too large to avoid damage to mechanism;

• Avoid stretching and bending cables;

• Please connect amplified piezo actuator and controller with special cable provided by
  CoreMorrow;

• Please do not extend the cable without authorization, please contact us if you need a longer cable.

5.3 Operating

• Please confirm the following information before starting the power supply:
• The environment meets requirements of amplified piezo actuator working environment;
• The positive and negative electrodes are connected correctly;
• The fixing screws must be tightened.
• The above information is determined to perform controller related operations:

1. Please carefully read piezo controller user manual before operating, then start the controller;
2. Set the piezo controller to zero;
3. After checking for no abnormalities, input voltage values according to requirements (keyboard or analog control);
4. It could work normally within the rated voltage range of piezo ceramic (0~120V, max not exceeding 150V);
5. Please set the piezo controller to zero after used.

Please do not touch the product during the operation, avoid affecting the piezo actuator performance or even damage the piezo 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.

Please do not loosen the screws on the actuator structure, avoiding to affect the accuracy of the actuator.

Daily cleaning:
Please disconnect the piezo actuator to 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 piezo 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 piezo actuator for protection, the piezo actuator  should not be too high from the sponge to prevent the piezo actuator from falling off.
