Do not disassemble P93 Fast Tool Positioning Stage.
Discharge P93 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.

• P93 Fast Tool Positioning Stage is used in a dust-free, oil-free and lubricant-free environment.

Product Overview

3.1 Product Introduction
P93 Fast Tool Positioning Stage has the following advantages:

• High performance piezo stack:
  P93 Fast Tool Positioning 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:
  P93 Fast Tool Positioning Stage 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.d.

• Capacitance Sensor
  The capacitance sensor converts the displacement signal into electrical signal and can directly measure the displacement of the moving part. The capacitance sensor has the advantages of high precision, stable temperature and good dynamic performance.

• LVDT Sensor
  LVDT sensor is a device to the measured displacement into the change of self- inductance or mutual inductance . It also measures the displacement of the moving part directly with high precision.
  P93 Fast Tool Positioning Stage has a travel range up to 118μm and features fast response speed, no mechanical friction,high repeatable positioning accuracy, high flexibility.

• Relative humidity: <60%
• Recommended voltage between 0 and 120V for long-term and high-reliability operation.

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 connection

1. Ensure that the installation plane is relatively flat;
2. Use M6(P93.X70) or M8(P93.X100) Screws to mount P93 on the mounting surface directly and tighten it;
3. Mounting the load and tighten it properly to ensure the positioning accuracy;
4. Connect the P93 connector with the corresponding controller according to the identification;
   The wiring mode of LEMO connector is shown as below:

Installation diagram is as follows:

5.2 Load
When mounting the load, ensure that the load quality is less than the maximum load capacity of P93, 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 long,The wrong mounting way is shown below.

It is forbidden to mount the load on one side of the moving platform, which will cause serious damage to the product, as shown 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.

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 P93 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 P93 has been grounded.
• The operating environment meets the operating environment requirements of P93.
• Fixed screws must be tightened.

1. P93 transport package (locking protective plates)
2. Preparation before installation(Remove two protective plates in left and right)
3. P93 normal service condition(Protective plates must be removed)

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 P93 in operation, do not knock the product, so as not to affect the use of the product or even damage the product.
In order to achieve better motion precision of P93, 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.

Notice:

• 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(150V) range of P93.
• If any abnormal noise or oscillation occurs during use, turn off the power immediately and check the parameter setting.
