how to operate the digital amplifier series 30DVxxx

8.1 common introduction

Our line of digital piezo amplifiers d-Drive from piezosystem jena has now been expanded with
the addition of the OEM amplifier series 30DVxxx including 30DV50 with 50mA output current
and 30DV300 with 300mA output current. These amplifiers are designed for use as a single unit
in industrial settings. It is compact, robust, and mountable in different manners and is highly
reliable. The 30DVxxx was designed for universal use with a wide main supply voltage from
10V to 30V DC. The casing is available in a screw slot version, or for mounting in a 19" rack
mount casing.
Piezo actuators can be controlled in three different ways, either by using the encoder knob on
the front panel, by analog signal ranging from 0 to +10V, or by PC-Interface RS232. The best
results for resolution and accuracy can only be achieved by setting the digital target values. The
high performance of the 30DVxxx with 20bit effective resolution guarantees the customer high
speed positioning, with the highest accuracy available. It includes rise time optimization and an
active oscillation damping for every special application.
The 30DVxxx comes with an auto calibration routine and automatic sensor identification (ASI).
All values of the actuating system, like capacitance, measurement system, resonant frequency,
and motion, are automatically stored in the amplifier. An automatic amplifier optimization occurs
after actuator identification. All this makes our system configuration very easy and saves our
customers a lot of time.
A unique feature of the 30DVxxx is that it can be used in combination with strain gauge or
capacitive feedback sensors without additional modification. The DSP (digital signal processor)
runs at 64 MHz, and at a sampling rate of only 20 µsec. We have also implemented adjustable
features such as slew rate, notch filter, and pass filters. A built-in function generator offers sine,
triangular, and square functions, as well as noise and sweep.
All operating elements are usable from the front side. The PC-interface on the back side allows
wiring in switch cabinets. Extension cables for great distances are available.
