1Introduction
The E-665 is a bench-top device for operating stages with low-
voltage piezoelectric translators (LVPZTs). All E-665 models
have RS-232, USB and I2C interfaces for computer control and
networking, a power amplifier, sensor excitation and readout
circuitry with different filters and a proportional-integral (P-I)
servo-controller. The integrated amplifier can output and sink a
peak current of 360 mA and an average current of 150 mA over
an extended voltage range of -30 to 130 V. The units can be
operated in both open-loop and closed-loop modes. Different
models are available for use with LVPZTs equipped with strain
gauge (SGS) or capacitive displacement sensors.
The E-665 can be operated manually by front-panel
potentiometers, by external analog signals or by computer over
a USB or RS-232 communications link. Up to 12 E-665s can be
controlled off a single computer interface. The block diagram on
p. 25 answers most questions about how the various elements
interact with each other. Commands are compatible with the PI
General Command Set (see the E-816 User Manual for
computer interfacing and command set details).
E-665s can be used for both static and dynamic applications.
High output stability and low noise assures stable
micropositioning. Because LVPZT translators have high
capacitances, the amplifier is designed to supply appropriately
high peak currents for dynamic applications. Excellent linearity
and stability allow the use of E-665s in precision measurement
and control systems.
1.1 How to use the Documentation
E-665 User Manual (this document)
This User Manual enables you to put your stage with the E-665
into operation for the first time. Furthermore, it gives an
overview of the E-665 functions and specifications.
Always keep this user manual available by the E-665.
The latest versions of the user manuals are available for
download on our website (www.pi.ws).
Add all information given by the manufacturer to the User
Manual, for example supplements or Technical Notes.

Introduction
www.pi.ws E-665 PZ127E Release 1.7.2 Page 4
If you pass the E-665 on to other users, also turn over
this User Manual as well as all other relevant information
provided by the manufacturer.
Only use the device on the basis of the complete User
Manual. Missing information due to an incomplete User
Manual can lead to injury as well as property damage.
Only install and operate the E-665 after having read and
understood this User Manual.
E-816 User Manual (E-816_User_PZ116Exxx.pdf)
provided on the E-816 CD
Remote control via computer interface ("computer-controlled
mode", p. 19) makes use of the E-816 computer interface
module which is integrated in the E-665. For detailed
instructions, descriptions and examples, refer to the E-816 User
Manual.
Software Manuals provided on the E-816 CD
During remote control via computer interface, the E-665 is
identified as “E-816”. Use the PC software and the
corresponding software documentation provided on the E-816
CD.
E-802 User Manual (PZ150E) and E-801 User
Manual (PZ117E) available for download at
www.pi.ws
In addition to the E-816 computer interface module, the
following submodules are integrated in the E-665:
E-802.55 servo-control submodule
With E-665.SR models only: E-801 sensor processing
submodule
The information given in the User Manuals of those submodules
is only relevant if you should ever need to re-calibrate your
system. For normal operation of the E-665, you do not need
those manuals because your system will be fully calibrated
before being shipped. Note that re-calibration should only be
done by adequate trained personnel and after consultation with
PI.

1.2 Intended Use
Based on their design and realization, E-665 LVPZT Amplifier
and Position Servo-Controllers are intended to drive capacitive
loads, in the present case, piezoceramic actuators. E-665 must
not be used for applications other than stated in this manual,
especially not for driving ohmic (resistive) or inductive loads.
E-665s can be operated in closed-loop mode using position
sensors (SGS or capacitive sensors). Appropriate sensors are
provided by PI and integrated in the stages according to their
product specifications. Other sensors may be used as position
sensors only with permission of PI.
Observe the safety precautions given in this User Manual.
If the E-665 is used in a manner not specified by PI, the
protection provided by the E-665 may be impaired.
E-665s meet the following minimum specifications for operation*
Indoor use only
Altitude up to 2000 m
Temperature range 5°C to 40°C
Max. relative humidity 80% for temperatures up to 31°C,
decreasing linearly to 50% relative humidity at 40°C
Line voltage fluctuations not greater than ±10% of the
line voltage
Transient overvoltages as typical for public power supply
Note: The nominal level of the transient overvoltage is the standing surge
voltage according to the overvoltage category II (IEC 60364-4-443).
Degree of pollution: 2
*Any more stringent specifications in the Technical Data table are, of course,
also met.

1.3 Safety Precautions
DANGER
Read This Before Operation:
E-665s are amplifiers generating voltages up to 130 V for
driving LVPZTs. The output power may cause serious
injury.
Only connect original PI parts to the »PZT« socket of the
E-665.
All work done with and on the devices described here
requires adequate knowledge and training in handling High
Voltages.
We strongly advise you to follow general accident
prevention regulations. Never touch any conductive
surface that might be connected to the High Voltage circuit.
Procedures which require opening the case should be
carried out by authorized, qualified personnel only.
Disconnect unit from power when opening the case, and
when resetting internal switches or jumpers.
Procedures which require operating the device with the
case open require adequate knowledge and training in
handling High Voltages and should be carried out by
authorized, qualified personnel only. When the unit must
be operated with the case open, voltages of up to 130 V
can be exposed. Do not touch internal conductors.
WARNING
Connect the AC power cord of the E-665 to a grounded
wall socket (115 VAC or 230 VAC).
Only use the supplied power cord or a sufficiently
dimensioned power cord to connect the E-665 to the power
source (ratings see table on p. 10).
Two new line power fuses are required when changing the
supply voltage. See p. 39 for more information.
To disconnect the system from the power source
completely, remove the power plug from the wall socket, or
remove the power cord from the E-665.
Install this unit near the AC outlet and such that the AC
power plug can be reached easily.

Introduction
www.pi.ws E-665 PZ127E Release 1.7.2 Page 7
CAUTION
Calibration should only be done by qualified authorized
personnel after consultation with PI, otherwise internal
configuration data may be destroyed by erroneous
operation.
If you inform PI about your application, your E-665s will be
fully calibrated before being shipped. It is usually not
necessary for you to do anything more than adjust the zero
point before operating the system.
CAUTION
Place the E-665 in a location with adequate ventilation to
prevent internal heat build-up. Allow at least 10 cm
(4 inches) clearance from the top and the rear of the unit
and 5 cm (2 inches) from each side.
Never cover the ventilation slots as this will impede
ventilation.
CAUTION
Thermally stable systems have the best performance. For
a thermally stable system, switch on the E-665 at least one
hour before you start working with it.
CAUTION
If the stage starts oscillating (humming noise):
In closed-loop operation, switch off the servo immediately.
The load and / or the dynamics of operation probably differ
too much from the setup for which the system was
calibrated.
In open-loop operation, stop the motion immediately. Do
not operate the piezo stage at its resonant frequency even
though the notch filter by default is also active in open-loop
operation.
Otherwise the piezo stage could be irreparable damaged.
