DECLARATION
Declaration!
This user manual is a integrated user manual of the Modular 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 Modular 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.
Cautious!
Modular 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.

Checking
Modular E70 controller has been carefully checked for electrical and mechanical aspects before shipment. When you receive the device, unpack and inspect the surface of the system for any obvious signs of damage. If it is damaged, it may be damaged during transportation, please contact our customer service department in time. Check whether the accessories are complete according to the packing list. Please keep the original packaging materials for subsequent maintenance and using.
Installment
Installation Precautions
Note! Improper installation of modular E70 series piezo controller may cause personal injury or damage modular E70 series piezo controller!

- Installation and using of modular 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 modular E70 series piezo controller system.
- If power cord provided by our company must be replaced, please use power cord with large enough size and effective grounding.
Ensure ventilation
Note! Overheating of equipment due to high temperature may damage modular E70!
- 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.
Connect power
Use power adapter (output range +20V~+30V/3A) to connect to power supply
interface of modular E70 power supply.
Cable connection
When the power supply is disconnected, connect the PZT&Sensor cable to modular
E70 interface. Note that the number on the piezo 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 modular 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.
