F2 Dynamic Operating Current Coefficient (DOCC)
Average electrical current (supplied by the amplifier) required to drive a piezo actuator per unit frequency and unit displacement (sine wave operation). For example, to find out if a selected amplifier can drive a given piezo tilt platform at 50 Hz with 300 Árad amplitude, multiply DOC coefficient by 50 and 300 and check if the result is less than or equal to the output current of the selected amplifier. For details see link ff. in the "Tutorial: Piezoelectrics in Positioning" section.
G2 Unloaded Resonant Frequency (f0)
Lowest tilt resonant frequency around active axis without mirror attached to platform (is above the maximum operating frequency). For further details see link in the "Tutorial: Piezoelectrics in Positioning" section.
G3 Resonant Frequency with Mirror
Example of how a load (mirror) attached to the platform affects the resonant frequency (calculated data). See "Dynamic Behavior" see link for further details.
Performance specifications are valid for room temperature (22 ░C +/-5 ░C) and closed-loop systems are calibrated for optimum performance in this range (specifications for other operating temperatures on request). Recalibration is recommended for operation at a significantly higher or lower temperature. Custom designs for ultra-low or ultra-high temperatures on request.
