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.

1.3 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.

Quick Start
www.pi.ws E-665 PZ127E Release 1.7.2 Page 12
1 Make sure that the E-665 is switched off (on-/off switch
on the rear panel is in „OFF“ position ( )).
2 Connect the E-665 to the line power. Strictly observe
the instructions in “Line Voltage Connection” on p. 10
3 Set the desired control mode using the
“ANALOG/DIGITAL” toggle switch on the E-665 front
panel:
ANALOG = analog mode
DIGITAL = computer-controlled mode
See “Control Modes” on p. 18 for details
4 Set the desired servo mode using the “SERVO
ON/OFF” toggle switch on the E-665 front panel:
OFF (down) = servo off (open-loop operation)
ON (up) = servo on (closed-loop operation)
See “Servo Modes (ON / OFF)” on p. 19 for details.
Notes:
The servo must be ON in analog mode, when you want
to work with a computer-generated signal (e.g. from a
DAQ board) and the analog LabVIEW driver set from
PI (see step 8 below).
To give the E-816 computer interface submodule
complete control over the servo mode selection, the
“SERVO ON/OFF” toggle switch on the front panel
must be set to OFF (down).
5 Connect the stage to the E-665. In a calibrated system,
controller and stage are not interchangeable. Respect
the assignment given by the serial numbers marked on
the calibration label of the controller.
6 Optional: Connect a suitable measurement device to
the “SENSOR MONITOR” BNC socket. This socket
carries the filtered and processed sensor output value,
with 0 to 10 V representing nominal travel range. See
“User Electronics and Sensor Monitor Signal” on p. 24
for further specifications
7 If you want to work with multiple E-665s, interconnect
their I2C bus lines. See “Networking on I2C Bus” on
p. 21 for details
8 If you want to work in analog mode:
Connect a suitable signal source to the “CONTROL IN”
BNC socket. This input signal is used as control input
and can also be a computer-generated analog signal
(e.g. from a DAQ board). You can use the PI LabVIEW
Analog Driver set provided on the included E-816 CD

Quick Start
www.pi.ws E-665 PZ127E Release 1.7.2 Page 13
to generate that analog signal. Install that driver set by
running Setup on the E-816 CD. See the driver
documentation on the E-816 CD for operation
9 If you want to work in computer-controlled mode:
Connect a suitable trigger signal to pin 9 of the “I/O
Connector” socket in the E-665 rear panel, see p. 52
for details. This signal is used as trigger input for wave
table operation and triggered motion described in the
E-816 User Manual.
10 Switch on the E-665 (move on-/off switch on the rear
panel into „On“ position (I)).
11 Command motion of the connected stage:
Analog mode: Change the control input signal on
“CONTROL IN” in the range of 0 to 10 V, and/or use
the “DC-OFFSET” potentiometer
Computer-controlled mode: Follow the instructions in
“First Steps” in the E-816 Computer Interface
Submodule User Manual
If at the yellow “OFL” overflow LED glows in closed-loop
operation (servo ON), then a zero-point adjustment is
necessary. Follow the instructions for zero-point adjustment
given in Section “Open-Loop Zero-Point Adjustment” on p. 32.
To avoid an overflow of the amplifier in open-loop operation, do
not exceed the allowable control input range (-2 to +12 V).

Operation
www.pi.ws E-665 PZ127E Release 1.7.2 Page 14
3Operation
The E-665 amplifier/controller is a stand-alone desktop device
designed to drive and control the displacement of a stage with
low-voltage piezoelectric actuators (LVPZT) in a system with
sensor position feedback (SGS or capacitive sensors,
depending on model type).
Operation involves the user commanding a motion and the E-
665 supplying the required voltage on the piezo output line for
the piezo to execute the commanded motion.

Voltage and Position Displays
4½ digit displays for analog mode.
In computer-controlled mode both displays are off (position and
voltage values are always available over the computer
interface).
“DC-OFFSET” knob
10-turn DC-offset potentiometer, adds 0 to 10 V to the
“CONTROL IN” signal (only relevant in analog mode)
“ON-T” LED, green
On target signal from E-802 servo-control submodule, glows if
the distance from target is less than ±0.19% of the travel range.
The signal (TTL active-low) is also on pin 6 of the “I/O
Connector” socket on the rear panel, see p. 52.
“OFL” LED, yellow
Overflow signal, indicates power amplifier is so near the end of
its range that it is no longer able to follow input changes
properly. If this LED glows in closed-loop operation (servo ON),
a zero-point adjustment is necessary. Follow the instructions for
zero-point adjustment given in Section Open-Loop Zero-Point
Adjustment” on p. 32. To avoid an overflow of the amplifier in
open-loop operation, do not exceed the allowable control input
range (-2 to +12 V).
“S-ON” LED, green
Servo mode indicator, permanent glow indicates that the servo
is ON (closed-loop operation).
“SERVO ON/OFF” toggle switch
Servo mode selection:
OFF (down) = servo off (open-loop operation)
ON (up) = servo on (closed-loop operation)
To give the E-816 computer interface submodule complete
control over the servo mode selection, this switch must be set
to open-loop operation (= OFF).
“SENSOR MONITOR” BNC socket
Filtered and processed sensor output value, 0 to 10 V
representing nominal travel range.
“SENSOR ZERO” potentiometer
Trim pot accessible with small screwdriver for sensor zero-point
adjustment. Readjustment may become necessary with time or
if the load is changed. Do the adjustment with Servo OFF! See
“Open-Loop Zero-Point Adjustment” on p. 32 for more details.

servo on, and reduce the lifetime of the piezo actuator).
The control input range can be shifted using the “DC-OFFSET”
potentiometer.
The control input voltage can also be a computer-generated
analog signal (e.g. from a DAQ board). You can use the PI
LabVIEW Analog Driver set provided on the E-816 CD to
generate that analog signal. See “Control Modes” on p. 18 for
details.
