the voltage display. The voltage display reading is the current PZT output voltage, and the value of
the displacement or angle is not meaningful because the piezoelectric actuator and sensor are not
connected.
If the system does not exhibit an abnormality when performing the above steps, the device has
passed the electrical check.
3.4 Connecting Cables
NOTE!
The E09 piezo servo control module of each channel is calibrated at the factory with the
corresponding piezo actuator, eliminating the need for the user to recalibrate. The piezo actuators
must be connected to the corresponding controller channel, and the number is indicated on the
rear panel label of the device to see if it corresponds to the number of the piezo actuator!
After the system has passed the electrical inspection, the piezoelectric actuator can be connected
to the system for corresponding operation. Please follow the steps below:
Turn off the system device.
Connect the piezoelectric actuator.
Each closed-loop piezoelectric actuator is equipped with two cables, a piezoelectric drive voltage
cable and a piezoelectric sensor cable, and each open-loop piezoelectric actuator is only equipped
with a piezoelectric drive voltage cable. Connect the piezo drive voltage cable to the PZT OUTPUT
output socket of the system's power amplifier module and the piezo sensor cable to the system's
piezo servo sensor SENSOR input socket.
3.5 Getting started
3.5.1 Simulation operation
prompt! The analog signal or other control signal given by the external analog input signal or
computer via DA can be used to generate the corresponding nominal analog signal!
Zero offset all DC-OFFSET bias potentiometers in the system.
Switch all servos to OFF (open loop operation).
(Note: In the closed-loop mode, the servo control circuit compares the control signal with the
sensor feedback signal as the final target signal. The effects of nonlinearity and drift are eliminated
in the closed-loop mode. The display module will display the position reading information in real
time. In the open loop mode, the servo control circuit is turned off. The device is a high voltage
amplifier, the input signal is amplified to the corresponding voltage to the piezoelectric ceramic
