E-709.1C1L digital piezo controller for capacitive sensors, 1 axis

E-709.1C1L: Operatings limits (open loop) with various piezo loads, capacitance values in µF

E-709.1C1L: Dimensions in mm

Cost-optimized, high-performance controller

For piezo-based single-axis nanopositioning systems with capacitive sensors. Output voltage -30 V to 130 V. Amplifier and sensor evaluation optimized for dynamic applications. Digital linearization. Digital servo controller can optionally be combined with profile generator and position feedforward control. Wave generator. Data recorder. Autozero. Trigger I/O. Supports all current ID chips from PI. Compact design with functional blocks for an easy derivation of OEM versions.

Temperature management

High position stability of the sensor electronics thanks to active temperature control. Adaptable to a wide variety of operating conditions. Temperature stable in less than 10 minutes after switching on. A short warm-up phase allows continuous operation to be dispensed with, therefore increasing the lifetime of the nanopositioning system while reducing energy requirement.

Safety and monitoring functionalities

Overtemperature protection for amplifier and sensor electronics. Short-circuit proof. Continuous, hardware-based measurement of input and output values such as voltage and current as well as internal temperature. High-frequency measurements for static and dynamic evaluation. Remote diagnostics possible thanks to specific query and recording of values.

Interfaces

USB and RS-232 (optional: RS-485) for commanding via PI General Command Set (GCS). Real-time SPI interface for position specification and query. High-bandwidth analog control input or sensor input. Analog output for sensor monitor or controlling an external amplifier. The servo cycle can be synchronized via differential inputs and outputs and the SPI interface.

Software interfaces

Extensive software support, e.g., for NI LabVIEW, C, C++, MATLAB, Python. Compatible with µManager. PIMikroMove user software.
