Analog and Pulsed Drivers for PILine
® The products described in thisdocument are in part protected
by the following patents: US-Patent No. 6,765,335. C-184, C-185 Analog Driver
® motors andstages can be operated in a
high-speed CW mode with
acceleration up to 20 g and
velocities up to 500 mm/s and
more. The CW mode is practi-
cal for applications where fast
end-to-end motion is required,such as shutter or switchingapplications.A flexible, programmablepulse generator with integrat-
ed C-180 driver is available as
C-170.161.
Ordering Information The C-185 analog driver con-trols the motor speed as a
function of a 10 V differentialanalog input. With an externalposition sensor and a con-
troller, it is thus possible to set
up a very fast, closed-loop sys-
tem. The M-663 stage (see p. 10-18) with integrated linearencoder can also be run withthis driver.For closed-loop systems, PIalso provides the C-865 con-
troller (see p. 9-12), which
already contains the analogdrive electronics.

M-665 Translation Stages; with
Power Supply C-180 to C-185 are single-chan-nel drive electronics for PILine
® ultrasonic piezomotors and
stages. They were developedfor customers who do not want
to use the fully integrated C-170 and C-865 PILine C-180, C-181 – Pulsed-ModeOperation
® Pulsed operation with C-180(OEM-Board) or C-181 (box
with interface
industrial connectors) is
especially suited for applica-
tions requiring small steps or
rapid end-to-end motion, as inmicroscopy, automation orsimilar applications. The motor
can be controlled with 5 V TTL
pulses connected to the signal
input on the driver electronics.
The width of the pulses willdetermine the approximatelength of the steps the motor
makes. The smallest possible
step is about 50 nm, requiring
a pulse of about 10 µs in dura-
tion. The pulse rate and widthcan be used to influence thestep size and rate, thus deter-
mining the velocity.In addition to the single-stepand step-sequence operating
modes, PILine con-trollers/drivers. Drive electron-ics for piezomotors convert an
analog or PWM input signal
into a high-frequency drive sig-
nal which excites the required
oscillations in the piezomotorand cause it to move. OEM or Packaged Electronics The philosophy behind thedesign of PILine
® ultrasonicdrives dictates that they be
easily adaptable to customer
requirements. This includesmaking the drive electronics,independent of control signal
type, available either as an
OEM board or as a stand-alone
unit in its own case. While the
OEM boards are the most eco-
nomic solution for large quan-tities, the stand-alone unitsmake it possible to plug a sys-
tem with PILine
