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.

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.

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 operation:
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.

3.5 Pin Assignment
"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 also
possible to connect two bender actuators (sharing the same
connector), but they cannot be commanded separately.
