E-625 Piezo Servo Controller

Piezo servo controller with position control

Single channel piezo servo controller for capacitive sensors (E-625.CR and E-625.C0) or strain gauge sensors (E-625.SR and E-625.S0). Integrated sensor module for strain gauge sensor evaluation in the E-625.SR and .S0. Integrated servo controller module for limiting the slew rate of the output voltage, notch filter, and servo loop.

Functions and interfaces

The E-625.CR and E-625.SR models with the E-816 computer interface submodule and therefore, additional functions:

• Multi-axis network: Several E-625s can be controlled from one single interface. A special network cable establishes communication between the individual controllers.
• Waveform memory: The user can save any function values in an internal table and output them by triggering. This makes it possible to repeat control motion profiles simply and reliably.
• General Command Set (GCS): For uniform control of nano- and micropositioning systems, the universal command set from PI is used. With GCS, control is independent of the hardware so that various positioning systems can be controlled together or new systems can be used with minimum programming effort.
