COREMORROW E52 Series Piezo Controller
DECLARATION
This user manual is a integrated user manual of the E52 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 E52 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
E52 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.

Power Calculation
- Average output（Sine wave operation mode）
- Pa ≈ Upp • Us • f• Cpiezo
- Pa=Average output[W]
- Upp=Peak and peak drive voltage [V]
- Us=Drive voltage[V]（（Vs+）-（Vs-））
- Cpiezo=Piezo actuator capacitance[F]
- f=Operating frequency of the sine wave[Hz]
Notes and Suggestions
- When the power used is large or the ambient temperature is high, external auxiliary heat dissipation can be considered.
- The temperature of the over-temperature power off protection is 75±5, but this function should be used as protection against accidents under limited conditions.
- When in normal use, please try to keep the top heat dissipation shell below 55.
- When the step amplitude is less than 3V, the peak current is small, less than 0.5A. As the step amplitude increases, the peak current also increases.
- When the step amplitude is greater than 10V, the peak current is greater than 17A.
- When the output power is too large or the output is short-circuited to the ground, the overcurrent indicator will light up, and the power supply part will
- output with a smaller cross-current.
- When the short circuit or power output is withdrawn, the overcurrent indicator goes out and the power supply returns to normal.
- But do not overflow for a long time.
- E52 cannot be used to drive inductive loads.
- If the inductive loads are driven, the product may be damaged.
- If there is no need, please do not twist the potentiometer easily.
Maintenance, Storage, Transportation
Cleaning Measures
Note The PCB board of the function module in the E52 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 E52 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.
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.
Note: Pay attention to frost when the E52 series piezo controller is powered on in winter to avoid burning the controller! Check whether the controller has frost before power on (frost usually occurs when moving from outdoor to indoor). If the controller is frosted, wipe it or dry it and store it indoors for more than two hours before powering it up for relevant operation.
