• 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:

• ZT50M14 is used as much as possible in dust-free, oil-free, lubricant-free environments;
• 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 piezo actuator and piezo controller;
• Please do not use cable extension wire, if need longer cable, please contact us.

Product Overview

Product Introduction
ZT50M14 piezo actuator has the following advantages:

• High performance piezo stack:
  ZT50M14 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.

• SGS sensor：
  SGS sensor detects position information by expanding, they are fixed at appropriate positions in transmission portion, and the displacement is measured.
  The sensor is connected through the full-bridge, without drift, and can be accurately located within the nano -range.
  ZT50M14 is designed for optical cage applications and can be installed directly in the cage structure. It integrates piezo stack into hand-adjusted two-dimensional lens regulator, wherein the lens can be pasted on the surface of the lens holder at the moving end of the piezo stack. First, the orientation of the lens is adjusted manually by the two-dimensional lens adjusting frame, and then the linear piezoelectric actuator is controlled by the electrical signal to make the linear motion with nanometer precision. The piezoelectric actuator has a variety of models and can be selected among various displacements.

• 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.

Installation and connection

1. Ensure that the installation plane is flat;
2. Secure the piezo actuator with M6 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.

ZT50M14 installation diagram is as follows:

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 piezo 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 ZT50M14 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.

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

• The environment meets requirements of ZT50M14 working environment;
• 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 actuator 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.

Note:

• Please do not remove the grounding protection during operation. If it needs to be temporarily removed, reconnect the grounding protection before starting again.
• Drive voltage should not exceed 150V;
• If abnormal noise or oscillation occurs during operating, immediately turn off the power check parameter setting.

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

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.
