Operating method of a piezolinear drive having a group of piezo stack actuators which drive a rotor, in which the actuators constitute a multilayer ceramic arrangement situated on a common substrate, wherein a first stack part within the stack of the multilayer arrangement is formed as a longitudinal actuator, and a second stack part as a shearing actuator, and the latter being at least indirectly in clamping and shearing contact with the rotor, and at least two identical actuators being situated next to each other in order to perform alternate clamping and advancing movements in the step operation for a rough positioning operation in the step mode, wherein the adjacent actuators of the group are controlled to perform alternate clamping and advancing movements, with control signals being derived from a speed-proportional control variable.
