What means "softstart"?
Softstart is a procedure that initializes your complete system consisting of a piezo actuator and an amplifier. After powering on, the amplifier starts to apply voltage until it has reached the full voltage range, and then cycles it back to zero. This way the piezo actuator moves from the minimum position to the maximum and back.
Piezo actuators in the nanoX, nanoSX, nanoSXY, and nanoMIPOS series, as well as some of the piezo tilting systems, start their cycle from the middle position to the maximum and then to the minimum (zero position). This cycle takes approx. 3 seconds. After this process the system is ready for operation.
