User Manual
Version: V1.0
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 specied 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 o the controller switch, such as
switching the servo state to the open-loop state.
Danger!
The piezoelectric power amplier 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 amplication requires training professional operators.
Cautious!
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.
Modular E70 housing should be installed on a horizontal surface in an area with a 3CM air ow
area to prevent internal convection in the vertical direction.
Insucient airow can cause equipment to overheat or premature instrument damage.

Modular E70 Series Piezo Controller User Manual
1.Security
1.1 Introduction
Please keep surface of Modular E70 clean and dry.
Do't operate in humid or static environment.
Modular E70 is used to drive capacitive loads (such as piezo ceramic actuators).
Modular E70 cannot be used in user manuals of other products with the same name.
Pay attention to Modular E70 cannot be used to drive inductive loads.
Modular E70 can be used for static and dynamic operating applications.
Modular E70 with SGS sensor can use closed loop operation mode.
1.2 Safety Instructions
Modular E70 is based on nationally recognized safety standards. Improper use may cause
personal injury or damage Modular E70. Operator is responsible for correct installation
and operation of it.
Please read the user manual in detail.
Please immediately eliminate any malfunctions and safety hazards caused by
malfunctions.
If the protective grounding wire is not connected or connected incorrectly, there will be
possibility of electric leakage. If you touch Modular E70 piezo controller, it can cause
serious or even fatal injuries.
If open Modular E70 privately, touching live parts may cause electric shock, resulting in
serious or even fatal injury or damage to the Modular E70 series controller.
Only authorized professional could open the Modular E70 series controller.
When opening Modular E70 series controller, please disconnect the power plug.
Please do not touch any internal parts when operating in an exposed state.
1.3 User Manual Notes
The contents described in user manual are standard product descriptions, special
product parameters are not described in detail in this manual.

The latest user manual is available for download on the company website.
When using Modular E70 series piezo controller, the user manual should be placed
near the system for easy reference in time. If the user manual is lost or damaged, please
contact our customer service department.
Please timely add all the information given in the manufacturer's user manual, such
as supplements or technical descriptions.
If your user manual is incomplete, it will miss a lot of important information, cause
serious or fatal injuries, and cause property damage. You have read and understood the
contents of the user manual before installing and operating the Modular E70 series piezo
controller.
Only authorized professionals who meet the technical requirements can install,
operate, maintain and clean the Modular E70 series of digital piezo controllers.
2.Features and Applications
Modular E70 can freely choose the number of cascaded modules according to the user's
needs. The number of channels for a single module is 3 channels/module, and up to 32
modules can be cascaded. It can be controlled by external analog signals or digital signals
via RS-422 interface and optional servo control function.

PZT&Sensor LEMO-ECG-2B-312 Output voltage to drive piezo actuator(PZT) . Sensor
input signal
Analog In SMB
Set DIP switch/software to select control mode. Analog
input is used as the target value of the input voltage.
The input voltage can be an analog signal generated
by computer(such as DA card). You can use signal
generator, analog signal source to connect.
Sensor
Monitor LEMO-EPG.0B-304 Sensor output signal monitoring terminal. Output range
is 0 to 10V
ZERO Potentiometer
Changing mechanical load or temperature changes will
cause deviation of sensor zero. No operating is required
after zero adjustment.( If closed-loop state works
normally, the zero point potential does not need to be
adjusted.)
Target LED yellow
When signal is not within range of target position, the
target detection abnormal indicator lights up.(TTL, active
low).
Limit LED red When output current of channel exceeds set value, the
corresponding over-current indicator lights up.

4.4 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.
