Piezo system specialist PI
introduces a breakthrough development in nanopositioning stage control. The
new E-709 provides digital functionality at the price-point of an analog controller,
all in the volume of a paperback book!
The true digital servo performance comes without compromise:
Features and Advantages
- 5th order polynomial digital linearization ensures higher accuracy than
- 2 notch filters allow faster response and piezo operation at higher frequencies
- A fast servo update rate ensures responsiveness
- DAC-in-the-loop architecture guarantees positional stability
- Several high speed interfaces: USB, RS-232, Real Time Analog and TTL
- Easy-to-use setup software for remote access and servo tuning. No trimpots!
- Extensive, well-documented, interface-independent software support includes
Windows .dll, Linux .so, and LabVIEW .llbs

Digital Piezo Control Functionality at a Breakthrough Price- One-Third
of the Nearest Competitor
The E-709 opens up the possibilities of digital control for piezo-driven nanopositioning
systems for the same price as analog controllers. It was designed for piezo
actuators and nanopositioning stages which low-cost piezoresistive sensors and
the higher performing capacitive sensors. The digital servo technology allows
higher linearity and precision and provides more control options (changeing
parameters on-the-fly, software optimized servo tuning, etc) and very comfortable
operation. The E-709 also includes a piezo power amplifier (driver). No additional
hardware is required to operate a piezo mechanics.
Comprehensive Software Support
In addition, PI provides the full functionality of its comprehensive software
packages free of charge. The E-709 can also be used for applications providing
analog control signals, as still widely used in microscopy applications. In
addition to 2 digital interfaces, a standard broadband analog input is installed
True Digital or Analog?
Many "digital" piezo nanopositioning controllers are actually analog
controllers with a USB or other communications interface grafted on. The digital
command is converted into an analog voltage by a D/A converter that sits outside
the servo loop and feeds the analog voltage to the servo. The servo technology
in these controllers remains analog (op-amps, capacitors, resistors), with its
inherent limits in accuracy, stability and functionality. A true digital controller
puts the DAC inside the servo loop.
