Safety Guide

H60 piezo hexapod 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 stage, 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 H60 piezo hexapod.
• Discharge H60 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.

• H60 piezo hexapod 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 H60 piezo hexapod Stage to controller.

• Do not connect via an extension cable casually, if you need a longer cable, please contact CoreMorrow.

Product Overview

Product Introduction

H60 piezo hexapod has the following advantages:

High performance piezo stack:

H60 piezo hexapod 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:

H60 piezo hexapod adopts 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.

H60 is a piezo stage with 6-axis motion of θx, θy, θz, X, Y, and Z. 6-axis movement in space is realized by the coordinated expansion and contraction of six piezoelectric actuators.
Closed-loop version has high positioning accuracy.

Product Features

• Motion in X, Y, Z, θx, θy, θz
• Small coupling
• Closed-loop version for high accuracy

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

1. Ensure that the installation plane is flat.
2. Secure the piezo stage with M4 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 head.

Installation diagram of H60 is as follows:

Load

When installing the load, ensure that the load mass is less than max load of H60, and install the load as much as possible at the center of the moving surface.

The correct placement of the load is shown below:

_
Load applied to the center of the stage_

For protection, we don’t recommend the load is too high. If it is used a higher load, please reduce the position center of the load gravity. The error placement method is as follows:

Try not to let the load center of gravity exceed the stage

It is forbidden to load the load on one side of the piezo stage, which would cause serious damage to the product, as shown in the following figure:

Do not load longer loads and add to the side of the piezo stage

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 stage 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 stage.

We recommend using the connection method shown below:

Correct connection

Please do not connect as shown below:

Incorrect connection

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 H60 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:

• H60 has been grounded.
• The environment meets requirements of H60 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 stage performance or even damage the piezo stage.
   The resolution of piezo ceramic 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.

Transportation and inspection

Transportation
