In order to prevent damage to the product caused by improper operation, the
following points should be paid attention to when in use.
P87 Amplified Piezo Actuator 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 P87 Amplified Piezo
Actuator.
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 P87 Amplified Piezo Actuator.
Discharge P87 before installation, 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.
2. Safety Guide
P87 Amplified Piezo Actuator is designed with the most advanced technology and safety
standards for your own safety and the correct use of the product, please observe the
following points when in use.

3. Product Overview
3.1 Product Introduction
P87 Amplified Piezo Actuator has the following advantages:
High performance piezo stack:
P87 Amplified Piezo Actuator 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:
P87 Amplified Piezo Actuator 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.
Strain 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 sensor is connected by a full bridge, no drift, and can be precisely positioned in the
nanometer range.

3.2 Product Features
Small size.
Closed loop strain gauge sensor, high positioning accuracy.
High resonant frequency.
Good dynamic performance
3.3 Motion direction
P87 Amplified Piezo Actuator can travel up to 38μm, with small size, no mechanical friction,
fast response speed, high repeatable positioning accuracy. This product can also be
customized according to the needs, with high flexibility, easy to operate, to meet different
applications.
P87 is mainly used in biotechnology, interferometry, quality detection, optical detection,
nanometer positioning, microscopy and imaging, image processing and other fields.

4. Operating environment
A clean, dustfree and non-corrosive environment
Operating temperature : -20~80℃
Relative humidity : <60%
Recommended voltage range is 0~120V for long-term use and lifetime
5. Installation and operation
Safety check should be carried out before installation, such as whether the connection wire
is damaged or broken, whether the drive power supply is grounded, etc.
5.1 Installation and Precautions
1. Make sure the mounting surface is flat.
2. Use M2.5 screws to mount the P87 and tighten.
3. Mount a load and tighten it properly to achieve high positioning accuracy.
4. Connect P87's connector to the corresponding interface of the controller according to
the identification on the leads.
When screwing M3 screws with one hand, in order to avoid deformation of the mechanism
or unnecessary damage, it is recommended to fix the actuator with the other hand

5.2 Load
When mounting the load, ensure that the load quality is less than the maximum load
capacity of P87, and try to mount the load in the center of the moving surface.
The correct position to mount the load is shown below:
FIG.3 The load is applied to the center of the moving surface
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.

FIG.4 Try not to let the position of the center of gravity far exceed the active platform
The wrong mounting way is shown in the figure below:
FIG.5 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.

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 P87 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 P87.
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 P87 in operation, do not knock the product, so as not to
affect the use of the product or even damage the product.
