Melles Griot 17 PCZ 013 Controller
The Melles Griot Piezoelectric Controllers with Feedback, Model 17PCZ013 is a Three-Channel Piezoelectric Controller with IEEE Interface. It provides active precision feedback control when used with active feedback actuators. An ultrasensitive position transducer monitors the exact extension of the piezo actuator and generates an error signal to close the position loop, thereby eliminating hysteresis and creep and achieving on-demand poistion at low nanometric levels.
The feedback loop has been desiged to drive a piezoelectric actuator at frequencies of 300 Hz with a step response of 2 to 3 milliseconds.
- Linearity response of better than +/- 0.5%
- Noise-equivalent motion less than 5 nm
- Voltage (V) and Position (um) modes
