PI Intros New Lower Cost Piezo Controller
Auburn, MA — PI has extended its E-616 multi-channel controller line for piezo-based steering and stabilization mirror platforms. Four open and closed-loop models are now available in benchtop and OEM module versions. The closed-loop units contain two servo controllers, sensor circuit channels and 3 power amplifiers.
The E-616 Multi-Axis Controller has three integrated amplifiers that provide up to 10W peak power; it is available in both closed-loop and open-loop versions; bench-top and OEM modules are available; internal coordinate transformation simplifies control of parallel kinematics designs (tripod and differential drive).
The controllers can drive parallel-kinematics (highest performance mechanics, where all piezo actuators are connected to the same moving platform) steering mirror designs. With the tripod design (for S-325 Z/Tip/Tilt mirrors), the platform is driven by three piezo actuators at 120° spacing. The quadra-pod differential drive design (as used in the S-330, or S-334 mirror models) runs two orthogonal axes with a fixed pivot point based on two pairs of actuators operating in push/pull mode. The differential evaluation of two sensors per axis improves linearity, stability and resolution.
To facilitate integration, setup and operation the E-616 has both front and rear panel connections: The 25-pin sub-D piezo and sensor connector is located on the front, along with offset trim pots and LEDs for Power and Overflow. A 32-pin rear connector allows commanding and reading the sensor and amplifier monitor outputs.
