Product Overview
Product Introduction
P70 piezoelectric nanopositioning scanner has the following advantages:
High performance piezo stack
P70 piezoelectric nanopositioning scanner is driven by high-performance piezo stack. The piezo scanner is fully insulated, so its performance and service life are far superior to those of conventional scanner. 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 scanner has the characteristics of no rebound, no wear.
Flexible hinge structure
P70 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.
SGS sensor
SGS sensor detects position information by expanding, they are fixed at appropriate positions in the transmission portion, and the displacement is measured. P70 piezoelectric nanopositioning scanner has two versions, namely twodimensional XY-direction motion and one-dimensional Z-direction motion. Both versions have four through holes at four corners with a 30mm hole center distance, making them ideal for cage construction. The XY motion version additionally has four countersinks and is also suitable for threaded mounting.
Product Features
- Quick response time.
- Closed-loop SGS sensor with high positioning accuracy.
- Mainly used for high frequency.
Motion direction
Operating environment
- Operating temperature: -20~80℃
- Environment free of dust, clean, and non-corrosive substances
- Relative humidity: <60%
- The 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
- Ensure that the installation plane is flat;
- Secure the piezo scanner with M2.5 screws and tighten;
- Connect ground protection, as shown.
- Install the load and tighten properly to ensure positioning accuracy;
- Connect the cable to the corresponding interface of the controller according to the connector head.

P70 installation diagram is as follows
Load
When mounting the load, ensure that the load quality is less than the maximum load capacity of P79, and try to mount the load in the center of the moving surface. The correct position to mount the load is shown below.
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:
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.
Excessive length of screws selected in the fastening and connecting process will lead to failure in installation or leakage of bolts, which will expose the product and scratch the product, affecting the motion accuracy of the product. Short bolts will lead to insufficient compactness of the connection and easy looseness, which will damage the internal structure of the product during operation.
We recommend using the connection as shown below
Please do not connect in this way as shown below
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 P79 and the controller.
- Do not connect via an extension cable casually, if you need a longer cable, please contact CoreMorrow
Operating
Please reconfirm the following information before turning on the power:
- The P79 has been grounded.
- The operating environment meets the operating environment requirements of P70.
- Fixed screws must be tightened.
After the above information is confirmed, relevant controller operations can be carried out:
- Please read the user manual of the controller carefully before operation, and then start the controller.
- Set the controller’ output voltage to zero first.
- Check no abnormal phenomenon, then input voltage value (via keyboard or analog control) according to the specified input voltage range.
- Operating normally within the rated voltage range of piezoelectric ceramics (0~120V, maximum 150V).
- After use, please carry out voltage reset operation.
Please take light steps when P70 in operation, do not knock the product, so as not to affect the use of the product or even damage product. In order to achieve better motion precision of P70, 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
- Do not remove the ground protection during operation. If it needs to be temporarily removed, please reconnect the ground protection before restart.
- The driving voltage shall not exceed the voltage range of P70.
- If any abnormal noise or oscillation occurs during use, turn off the power immediately and check the parameter setting.
