S22 Piezo Tip/tilt Platform User Manual 1. Introduction 1.1 Purpose and content The manual is mainly for your smooth and correct use of FSM. The manual contains all necessary information for S22 series. The manual describes the precautions during installation and use. 1.2 Symbol and meaning DANGER: Improper handling may could cause injury to the operator. Attention: Improper handling can cause damage to the equipment. No order between items. 1. 2. Please operating in order. 1.
2. Safety Guide S22 piezo tip/tilt platform is designed with advanced technology and safety standards, for safety and proper use of the product, please pay attention to following points when using: Temperature changed and pressure will charge the piezo tip/tilt platform. It will remain charged for a period of time disconnected from the controller, so the operator should pay attention when using it: Do not disassemble S22 piezo tip/tilt platform.
S22 Piezo Tip/tilt Platform User Manual 3. Product Overview 3.1 Product Introduction S22 series piezo tip/tilt platform has the following advantages: High performance piezo stack: S22 piezo tip/tilt platform is driven by high-performance piezo stack. It is fully insulated, so its performance and service life are far superior to those of conventional platform. The insulating layer could effectively prevent the piezo stack from being damaged by moisture.
3.2 Driving Principle S22 driving principle 0V Output voltage 电压输出 PZT ---------------------------- AXIS S22 driving principle The piezo tip/tilt mirror is designed based on a single piezoelectric ceramic structure, using piezoelectric ceramic, deflecting movement in a push-pull mode stroke, and using a bridge connection circuit control, which could eliminate the influence of temperature on the piezoelectric ceramic, under a wide range of temperature changes Maintain good angular stability.
S22 Piezo Tip/tilt Platform User Manual X-axis tilt angle: θ X = LPZT / a where, LPZT - PZT travel range a - Distance between PZT and rotation axis Dynamic characteristics of piezo tip/tilt platform: Operating frequency of S22 depends on the resonance frequency. In order to estimate the resonance frequency (moving surface and lens) after loading the lens, the rotational inertia of the lens must be taken into account.
The overall resonance frequency can be calculated using the unload resonance frequency and the rotational inertia of the lens. The calculation formula is as follows: f0 f = 1 + Im / I0 ' where, f ' - Overall resonance frequency I 0 - Rotating inertia of unload moving surface f - Unload resonance frequency I m - Rotational inertia of lens 3.3 Features θx tilt Tilt angle up to 4mrad Sub-ms response time High closed loop positioning accuracy 3.4 Moving direction AXIS1 Figure3.
S22 Piezo Tip/tilt Platform User Manual 4. Operating environment Operating temperature: -20~80℃ Environment free of dust, clean, and non-corrosive substances Relative humidity: <60% Recommended voltage between 0 and 120V for long-term and high-reliability operation. 5. Installation and operation 5.1 Installation and connection Before installation, first check the safety, such as whether the cable is damaged or broken, and whether the power supply has grounding protection.
2. Choose the mounting bracket or install the piezo tip/tilt platform through the transfer method. It is recommended to use M3 screws. Clean the mounting bracket before installation, or you can contact us to select the appropriate transfer method for installation. 3. S22 is fixed on the installation plane or fixed on the installation plane through related tooling. Please note that if the related rotating mirror products need to be placed in other places (such as side, oblique, etc.
S22 Piezo Tip/tilt Platform User Manual 5.2 Load When installing the load, ensure that the load mass is less than the max load of the S22, and install the load as much as possible at the center of the moving surface. The correct placement of the load is shown below: Figure7. 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: Figure8.
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 S22 piezo tip/tilt platform 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. 5.
S22 Piezo Tip/tilt Platform User 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. 6. Transportation and inspection 6.1 Transportation Piezo stage is packed in carton.
caused by bumps; Please do not use heavy tools or use rough methods to open them;； Please do not discard all packaging materials for return shipments. 7. Maintenance and processing 7.1 Problem Processing Common problems are shown in the following table: Problem Description Possible reasons The cable is not connected correctly or is in faulty contact.
