Percussion unit

A percussion mechanism unit, comprising:

• a control unit configured to control a pneumatic percussion mechanism by one or more of open-loop control and closed-loop control,
• wherein, in at least one operating state in which an operating parameter is set at an above-critical working value, the control unit is configured to set the operating parameter temporarily to a starting value in order to change from an idling operating state to a percussive operating state,
• wherein the operating parameter is a percussion frequency of the percussion mechanism unit that drives a striker that is coupled to the percussion mechanism unit and the starting value lies in a frequency range below a critical working value frequency in which an amplitude of oscillation for the striker has a single value based on a predetermined relationship of the percussion frequency at the starting value to the amplitude of the striker, and
• wherein the above-critical working value is set to a percussion frequency of the striker in the percussion mechanism unit at a frequency that is above the critical working value frequency in a frequency range in which the amplitude of oscillation for the striker corresponds to a plurality of values based on the predetermined relationship of the percussion frequency at the above-critical working value to the amplitude of the striker.
