E-625 Piezo Servo Controller
INFORMATION
Thermal instabilities can reduce the performance of the E-625 directly after it is switched on.
Switch on the E-625 at least one hour before starting work.
If the device is not in use, but should remain switched on to ensure the temperature
stability:
Make sure that servo mode is switched off (open-loop operation) and the piezo output
voltage is set to 0 V:
−
Analog mode: The input voltage for the target value is 0 V
−
Computer-controlled mode: Corresponding commanding

Perform System Test
During the first startup, do a system test under conditions typical to your application.
This ensures that the E-625 and the positioner are optimally adapted to your conditions
of use.
INFORMATION
If you do the system test in the computer-controlled mode, you will not require a function
generator or a voltmeter. You can then use the wave table output to generate a square-wave
signal (to determine the resonant frequency and the settling behavior of the positioner), and
read out the position and output voltage via query commands.
For more information, refer to the user manual for the E-816 computer interface submodule.
Requirements
You have read and understood the general notes on startup (p. 23).
The E-625 has been installed properly (p. 15).
You have installed the positioner in the same way as it will be used in your application
(corresponding load and orientation).
The E-625 is switched off, i.e., the wide input range power supply is
not
connected to
the power socket with the power cord.
You have the user manual of the E-802 servo controller submodule within reach.
Tools and Accessories
Oscilloscope; recommended: Digital storage oscilloscope (p. 18)
Function generator for the output of a 1-V square-wave signal with 2 to 5 Hz
Voltmeter
2 SMB/BNC adapter cables (included in the scope of delivery)
