DECLARATION

Declaration!
This user manual is a integrated user manual of the E70 series piezoelectric controller. Please read this user manual carefully before using this controller. Follow the instructions in the manual during use. If there is any problem, please contact us for technical support. If you do not follow this manual or disassemble and modify the product yourself, the company will not be liable for any consequences arising therefrom. Please read the following to avoid personal injury and to prevent damage to this product or any other product connected to it. In order to avoid possible hazards, this product can only be used within the specified range.
Notice!
Do not touch any exposed ends of the product and its accessories. There is high voltage inside. Do not open the case without permission. Do not connect or disconnect input, output, or sensor cables with power on. Please keep surface of E70 clean and dry, don’t operate in humid or static environment. After use, output voltage should be cleared to zero before turning off the controller switch, such as switching the servo state to the open-loop state.
Danger!
The piezoelectric power amplifier described in this manual is a high-voltage device capable of outputting high currents, which can cause serious or even fatal damage if not used properly. It is strongly recommended that you do not touch any parts that connect to the high voltage output. Special Note: If you connect it with other products in addition to our company, please follow the general accident prevention procedures. Operating the high-voltage amplification requires training professional operators.
Warning!
If the voltage exceeds the PZT’s tolerable range, it will cause permanent damage to the PZT. Before adding voltage to the PZT poles, it must be ensured that the positive and negative poles of the PZT are connected correctly and the operating voltage is within the allowable range of this PZT.
Cautious!
E70 housing should be installed on a horizontal surface in an area with a 3CM air flow area to prevent internal convection in the vertical direction. Insufficient airflow can cause equipment to overheat or premature instrument damage.

Features and Applications

E70 series piezo controller is a 3-channel piezoelectric ceramic controller with small size, high power, low power consumption, high bandwidth and low ripple noise. The controller uses a dedicated operational amplifier circuit to ensure high-voltage and high-current output capability. By optimizing the sensing servo module, the accuracy and stability of control are improved. The reliable anti-interference design ensures the high-frequency response of the controller.

Installment

4.1 Installation Precautions
Note! Improper installation of the E70 series piezoelectric controller may cause personal injury or damage the E70 series piezoelectric controller!
Installation and using of E70 should be close to the power source, so that the power plug can be easily and quickly disconnected from the main power source.

• Use included power cord to connect E70 series piezoelectric controller system.
• If power cord provided by our company must be replaced, please use power cord with large enough size and effective grounding.

4.2 Ensure ventilation
Note! Overheating of equipment due to high temperature may damage the E70 controller!

• Ensure that the cooling area of the controller is sufficiently cooled.
• Ensure that there is adequate ventilation equipment.
• Keep ambient temperature to non-critical level(<50 ).
• Temperature of cooling surface of controller>50 , it is recommended to take external heat dissipation measures to improve the stability of the controller.

4.3 Connect power
Use power adapter (output range +20V~+30V/3A) to connect to power supply interface of the E70 power supply.
4.4 Cable connection

• When the power supply is disconnected, connect the PZT&Sensor cable to the E70 controller interface. Note that the number on the piezoelectric actuator corresponds to the number of the controller.
• Analog control mode, when the signal source (signal generator, analog signal source, DA control card) output is 0, connect the SMB cable to the SMB interface of the E70 controller.
• Connect to the computer control mode of PC, connect to PC through the cable connection USB interface or RS-232/422 interface socket.

Maintenance, storage, transportation

8.1 Cleaning measures
Note! The PCB board of the function module in the E07 system is an ESD (electrostatic discharge) sensitive device. Take precautions against any static build-up of these devices before use to avoid contact with circuit component leads and PCB wiring. Before touching any electronic components, the body first touches the grounding conductor to discharge static electricity, ensuring that any type of conductive particles (metal, dust or debris, pencil lead, screws) enter the device. Be careful not to drop the equipment when cleaning, to avoid any form of mechanical shock!
Disconnect the power plug of the E70 system before cleaning.
Prevent cleaning fluid and any liquid from entering the system module to avoid short circuits.
The surface of the system chassis and the front panel of the module, please do not use an organic solvent for surface wiping.
8.2 Transportation and storage
This product is packed in carton. Transportation must be carried out under product packaging conditions, and direct rain and snow, direct contact with corrosive gases and strong vibrations should be avoided during transportation.
The instrument can be transported under various conditions of normal transportation, and should avoid damp, load, collision, extrusion, irregular placement and other adverse conditions during transportation.
If the instrument is not used for a long time, the instrument should be packaged and stored. The instrument should be stored in a non-corrosive atmosphere and in a well ventilated, clean room.
In the process of transportation, storage and use, attention should be paid to fire prevention, shockproof, waterproof and moisture proof.
