The invention relates to a standby control for machine tools for regulating the energy consumption of individual energy consuming components of the machine tool during the non-operation / standby phase of the machine tool. When the standby control starts, individual one of the power-consuming components is closed, so that the precision condition or precision of the individual components is adjusted during the non-operation time of the machine tool, therefore the machining accuracy of the entire machine tool is adjusted. When the machine tool starts, the starting or closing of the power-consuming components is executed through determining an input value EW, the input value EW can have electric sliding control with visual mode and corresponding to the expected machine precision.
