In order to prevent damage to the product caused by improper operation, the
following points should be paid attention to the following points when in use.
N60 piezoelectric nanopositioning stage should be used in a dust-free, oil-free and
lubricant-free environment.
As the product is designed with flexible structure, it is recommended that the load
should not exceed load capacity of 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;
Use the dedicated cable provided by CoreMorrow to connect N60 piezoelectric
nanopositioning stage to controller.
Do not connect via an extension cable casually, if you need a longer cable, please
contact CoreMorrow.
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 when in use.
Do not disassemble N60 piezoelectric nanopositioning stage.
Discharge N60 before mounting, which can be done by connecting to the
controller.
Do not unplug the wire connecting with 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.

3. Product Overview
3.1 Product Introduction
N60 piezoelectric nanopositioning stage has the following advantages:
High performance piezo stack:
N60 piezoelectric nanopositioning stage 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 mechanism, there are no transmission parts and friction. Therefore, ceramic
actuator has the characteristics of no rebound, no maintenance, and no wear, etc.
Flexible hinge structure:
N60 piezoelectric nanopositioning stage adopting flexible hinge mechanism has
advantages of no friction, high positioning accuracy. Flexible hinge is an element not
affected by static and dynamic friction, based on the elastic deformation of metal material
(e.g., steel) , there is no rolling and sliding parts. Flexible unit has very high load capacity
and stiffness. Hinge guide needs no maintenance and no wear and tear. Suitable for a wide
range of temperatures, no lubricating oil is required.
SGS sensor：
Strain sensor detects the position information by its 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 maximum X-axis stroke of N60 piezoelectric nano-positioning table can reach 34μm,
which has the advantages of no mechanical friction, fast response speed and high repeated
positioning accuracy, high flexibility, and easy to operate, and suitable for different

5.1 Installation and connection
You need to use M2.5 screws to mount the N35, and you also can adopt a adapter, and we
have many adapters for your choice, as shown below. And before mount, please clean the
mounting surface and adapter.
1、Make sure the mounting surface is flat.
2、Use M2.5 screws to mount the N60 and tighten.
3、Mount a load and tighten it properly to achieve high positioning accuracy.
4、Connect N60's connector to the corresponding interface of the controller according
to the identification on the leads.
The connection mode of LEMO connector is shown in the following figure.

5.2 Load
When mounting the load, ensure that the load quality is less than the maximum load
capacity of N60, and try to mount the load in the center of the moving surface.
The correct position to mount the load is shown below.
FIG.4 The load is applied to the center of the moving surface

N60 Piezo Nanopositioning Stage User Manual

FIG.5 Try not to let the position of the center of gravity far exceed the active platform
FIG.6 Do not mount long loads on one side of the platform
It is forbidden to mount the load on one side of the moving platform, which will cause
serious damage to the product, as shown in the figure below.
Too long screws selected in the fastening and connection process will lead to failure of
mounting or part of bolts will be exposed, which will scratch the product and affect the
motion accuracy of the product. If the bolt is too short, the connection will be weak, and
it is easy to be loosened. Loosening during operation will damage the internal structure of
the product.
For the protection of the product, we do not recommend that the load is too high. If a
higher 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.

FIG.7 Correct bolt connection
Please do not connect in this way as shown in the following figure.
FIG.8 Inappropriate bolt connection
We recommend using the connection method shown in the figure 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 N60 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:
The operating environment meets the operating environment requirements of N60.
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’ output voltage to zero first.
3.Check no abnormal phenomenon, then input voltage value (via keyboard or analog
control) according to specified input voltage range.
4.Operating normally within the rated voltage range of piezoelectric ceramics (0~120V,
maximum 150V).
5.After use, please carry out voltage reset operation.
Please take light steps when N60 in operation, do not knock the product, so as not to
affect the use of the product or even damage the product.
The resolution of the product itself is unlimited, and the resolution depends on the
performance of the controller. In order to achieve better motion precision of N35, 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 grounding protection during the 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 N60.
If any abnormal noise or oscillation occurs during use, turn off the power immediately
and check the parameter setting.
