E81.A1K Series Piezo Controller
User Manual
Version: V1.0

Declaration!
This user manual is a integrated user manual of the E81.A1K 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 specied 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 E81.A1K 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 amplier 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 amplication 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.
E81.A1K 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.
Insu󰀩cient airow can cause equipment to overheat or premature instrument damage.

E81.A1K Series Piezo Controller User Manual
1.Security
1.1 Introduction
Please keep surface of E81.A1K clean and dry.
Do not operate in the humid or static environment.
E81.A1K is used to drive capacitive loads (such as piezo actuators).
E81.A1K should not be used in user manuals of other products of the same name.
Pay special attention E81.A1K cannot be used to drive resistive or inductive loads.
E81.A1K could be used for static and dynamic operating applications.
1.2 Safety Instructions
E81.A1K is based on the national safety standard. Improper use may cause personal injury
or damage to the piezo controller. The operator is responsible for the correct installation
and operation of the piezo controller.
Please read the user manual in detail.
Please eliminate any faults and potential safety hazards caused by the faults.
If the protective ground wire is not connected or connected incorrectly, there will be a
possibility of leakage. If you touch the E81.A1K piezo controller, it may cause serious or
even fatal injuries.
If the piezo controller housing is opened without permission, touching the live parts
may cause electric shock, resulting in serious or even fatal injury or damage to the piezo
controller.
Only authorized professional technicians with corresponding qualifications could
open the piezo controller.
When opening E81.A1K series controller, please disconnect the power plug.
Please do not touch any internal parts when operating under bare conditions.
1.3 Notes
The contents in the user manual are all standard descriptions, and the customized
parameters are not explained in detail in this manual.
