Safety Guide

P84 Piezo Micrometers 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.

A change in temperature and pressure will charge the piezoelectric actuator, and the actuator will remain energized 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 P84 Piezo Micrometers.
• Discharge P84 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.

In order to prevent damage to the product caused by improper operation, the following points should be paid attention to when in use.

• P84 Piezo Micrometers is 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 N35 Piezo Tip/Tilt Platform to controller.
• Do not connect via an extension cable casually, if you need a longer cable, please contact CoreMorrow.

Product Overview

Product Introduction
P84 Piezo Micrometers is composed by a standard micrometer and a piezo stage that can produce high resolution displacement. 13mm travel from micrometer is manually adjusted and 100μm piezo travel is controlled by driving voltage.
Through free combination, P84 can realize 1~3 dimensional movement. Piezoelectric ceramic is used as the core driving element of the system. The flexible hinge guiding system with zero friction characteristics is optimized through finite element analysis to achieve precise motion control. The flexible hinge has high stiffness , high resolution and no wear.
P84 can choose a built-in high-precision displacement sensor for full closed- loop position feedback, which can ensure the linearity and repeat positioning accuracy of the system, and effectively eliminate the hysteresis and creep characteristics of piezoelectric ceramics. It is a high-precision instrument that meets national standards.

Principle
The piezo control principle is as follows:

Note: Open-loop piezoelectric actuators have no sensors

Product Features

• Built-in high-performance piezoelectric ceramics, high reliability.
• Optional built-in precision displacement sensor.
• Compact and easy to integrate.
• Mainly used in static positioning system.

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

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.

Installation and Precautions
Installation diagram of P84 is as follows:

The installation diagram is as follows:

Instructions:

1. Lock handwheel
2. Motion platform
3. Mounting hole (M6 screw)
4. Load mounting hole (M6 screw)
5. Load mounting hole (M3 screw)

Installation procedure

A) During installation, it shall be handled with care to avoid damaging P84 Piezo Micrometers.
B) Loosen the hand wheel at the bottom, push open the moving platform in the direction shown in Figure 5, screw and lock the hand wheel. After mounting the platform with M6 screws, hold the moving surface, slowly loosen the hand wheel, and make the platform slowly rest on the micrometer.
C) Connect the product connector to the corresponding interface of the controller according to the connector identification.
The wiring mode of LEMO connector is shown below:

Load
Please refer to the following loading method for mounting load, as 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.
The wrong mounting way is shown in the figure below:

FIG.8 Try not to let the position of the center of gravity far exceed the active 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.

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.
Please do not connect in this way 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 P84 and the controller.
• Do not connect via an extension cable casually, if you need a longer cable, please contact CoreMorrow.

Operating
The stroke of P84 Piezo Micrometers consists of the displacement of micrometer and that the piezo mechanism. The displacement of the micrometer is manually adjusted, and the displacement of the piezo mechanism is adjusted by piezo controller. The operation is as follows.

Please reconfirm the following information before turning on the power:

• The operating environment meets the operating environment requirements of P84.
• 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 P84 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 P84, 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.
