OEM modules for low-voltage piezo actuators

E-610 amplifier / servo controller modules are designed for operating low-voltage piezo actuators and positioning systems. They are equipped with an integrated low-noise piezo amplifier that can input and output peak currents of 140 mA in the low-voltage range. Four versions are available: E-610.00 (amplifier only) as well as the E-610.S0, E-610.L0, and E-610.C0 versions with additional components for control as well as measuring the position. The E-610.S0 was designed for piezo mechanics with strain gauge positioning sensors, the E-610.L0 for systems with LVDT sensors, and the E-610.C0 for systems with capacitive sensors.

Control via PC

The E-621 and E-625 models are available for control via a digital PC interface. Alternatively, analog control is possible from the PC via D/A converter. PI offers a full driver set for use with NI LabVIEW software for certain D/A converter boards from National Instruments.

Closed-loop and open-loop piezo positioning

The E-610 modules offer precision control of piezo actuators and piezo positioning systems both in closed-loop and voltage-controlled operation. The piezo controllers already have electronics for position sensing and position control. The control signal controls the piezo position directly. A positioning accuracy and repeatability in the nanometer range is therefore possible depending on the piezo mechanics and the sensor type.
