E-861 PiezoWalk® NEXACT® Controller for linear drives and positioners by PI

The new, compact E-861 controller is designed to operate NEXACT^® linear drives and closed-loop positioning systems using them, simply and precisely. In perfect harmony with the mechanics, the E-861 supports both motion modes of the PiezoWalk^® stepping drive: for longer moves, the stepping mode, and for moves shorter than typically 7 µm, the analog mode, which provides high-dynamics positioning with resolutions of less than 1 nm. The NEXACT^® drive design minimizes piezo operating voltages to 45 V and below.

E-861 controllers offer a number of features to support automation and handling. For example, macros can be stored in non-volatile memory.
A programmable autostart macro allows stand-alone operation without external communication. Upon power-up, the macro with its internal command sequence is executed automatically.

For easy synchronization of motion with internal or external trigger signals, four input and four output lines are provided.

Multi-Axis Operation
Up to 16 E-861 controllers can be networked and controlled over a single PC interface.

Such daisy chain networks are flexible, can be extended at any time and are compatible with other PI controllers (e.g. DC servo-motor and stepper motor controllers).

Easy System Setup, Comprehensive Software
All parameters can be set and checked by software. System setup and configuration is done with the included PIMikroMove user-interface software. Interfacing to custom software is facilitated with included LabView drivers and DLLs. With the PI General Command Set (GCS), system programming is the same with all PI controllers, so controlling a system with a variety of different controllers is possible without difficulty.
