high frequencies in closed loop mode
Can actuators equipped with strain gauges be operated with high frequencies in closed loop mode?
No, the highest frequency actuators with strain gauges can reach is around 30 Hz.
The bandwidth of the sensor pre-amplifier is 5 kHz, nevertheless the control electronics still need time to process the signals and to correct the actuator´s position.
A frequency of about 100 Hz can be reached by optimizing several parameters of the control electronics. This is done by piezosystem jena within the context of a special calibration.
