1.1 Intended Use
The E-650 is a laboratory device according to DIN EN 61010-1.
It is intended to be used in interior spaces and in an
environment which is free of dirt, oil and lubricants.
The E-650 is designed and intended for driving capacitive loads
(e. g. piezo ceramic actuators).
The E-650 must not be used for purposes other than those
named in this user manual. In particular, the E-650 must not be
used to drive ohmic or inductive loads.
The E-650 can be used for static as well as dynamic
applications.
1.2 General Safety Instructions
The E-650 is built according to state-of-the-art technology and
recognized safety standards. Improper use can result in
personal injury and/or damage to the E-650.
Only use the E-650 for its intended purpose, and only
use it if it is in a good working order.
Read the user documentation (user manuals, Technical
Notes).
Immediately eliminate any faults and malfunctions that
are likely to affect safety.
The operator is responsible for the correct installation and
operation of the E-650.
Install the E-650 near the power source so that the
power plug can be quickly and easily disconnected from
the mains.
Use the supplied components to connect the E-650 to
the power source.
If one of the supplied components for connecting to the
power source has to be replaced, use a sufficiently
dimensioned component.
Only use cables and connections that meet local safety
regulations.
www.pi.ws E-650 Piezo Amplifier PZ 97E Release 1.1.0 Page 2
Safety
If an E-650 OEM module is operated without a housing, live
parts will be accessible. Touching the live parts can result in
minor injury. Electrical, magnetic and electromagnetic fields
emitted by live parts can disturb the E-650 OEM module and/or
the environment.
Only operate the E-650 OEM module when it is installed
in a shielded housing that securely encloses all live
parts and fulfills the requirements of electromagnetic
compatibility.
Since parts of the circuit will store charge, precautions
must also be taken when the E-650 OEM module is not
powered. After switching off the E-650 OEM module,
wait a minute before you touch parts of the E-650 OEM
module to be sure that any residual voltage has
dissipated.
The E-650 contains electrostatic-sensitive devices (ESD) that
can be damaged if handled improperly.
Avoid touching assemblies, pins and PCB traces.
Before you touch the E-650, discharge yourself of any
electric charges, e.g., by wearing an antistatic wrist
strap.
Only handle and store the E-650 in environments that
dissipate existing static charges to earth in a controlled
way and prevent electrostatic charges (ESD protected
workstation or electrostatically protected area, in short
EPA).
Before cleaning, disconnect the E-650 from the power
source by removing the mains plug.
1.3 Organizational Measures
User documentation (user manual, Technical Notes):
Always keep this user documentation available by the E-
650.
The latest versions of the user documentation are
available from PI.
Add all information given by the manufacturer to the
user documentation, for example supplements or
Technical Notes.
If you pass the E-650 on to other users, also turn over
the user documentation as well as other relevant
information provided by the manufacturer.

Safety
Only use the device on the basis of the complete user
documentation. Missing information due to an
incomplete user documentation can result in minor injury
as well as property damage.
Only install and operate the E-650 after having read and
understood this user manual.
1.4 Personnel Qualification
The E-650 may only be installed, started up, operated, and
cleaned by authorized and qualified staff.

Introduction
2 Introduction
E-650.00 is a benchtop amplifier especially designed for
PICMA
®
multilayer bender actuators from PI such as the
PL-112 to PL-140. It contains one amplifier that can output and
sink a peak current of 300 mA.
An OEM version is also available (E-650.OE, see p. 10).
Features:
Specially Designed to Drive Multilayer "Bimorph"
Actuators
Benchtop device only: LCD Voltage Display
Output Voltage Range 0 to 60 V
One Fixed Voltage for Full Differential-Voltage Control
The PICMA
®
actuators require full differential-voltage control
with constant voltages of 0 V and +60 V and a variable voltage
from 0 V to +60 V (see Fig. 1). Note that a control input voltage
of 5 V corresponds to a PZT variable output of about +30 V,
which puts the actuator in the middle position (i.e. deflection ≈
0 μm).

3.3 Operation
External oper at ion:
Output voltage is controlled by an analog signal applied to the
BNC input, ranging from 0 to 10 V. Multiplying by the gain factor
of 6, an output voltage range of 0 to 60 V results. The DC offset
potentiometer can be used to bias the control input voltage. The
control voltage is applied to the input socket (BNC connector)
"Control Input", Input range: 0 ...+10 V.

Manual Operation:
Output voltage can be set by a 10-turn, DC offset potentiometer
in the range of 0 to 60 V.

"PZT Output" connector
Fig. 3: Pin Assignment
Pin 1 is internally connected to pin 2 and pin 4 is internally
connected to pin 5, so that the appropriate output voltages are
present on both pins of such a "pair" in parallel. It is als o
possible to connect two bender actuators (sharing the same
connector), but they cannot be commanded separately.
