Programmable linear drive, in particular for an electrode holder as well as method for the control of the linear drive

摘要

The subject matter of the present invention relates to a programmable linear drive (1) and a method for controlling a programmable linear drive (1), comprising a double-acting, with a working piston (8) provided with the pneumatic cylinder (2) and of a programmable pressure regulating unit (3), comprising at least a multiway valve to the pressure means exposure of the pneumatic cylinder (2), at least one sensor (11) for the acquisition of measured values, as well as a in an electronics housing (9) of the drive electronics for driving the multiway valve, wherein the pressure regulating unit (3) at least two mutually independent control circuits for the pressurization of two, by means of the working piston (8) separate working chambers (7a, 7b) of the pneumatic cylinder (1) to a continuous movement of the working piston (8) to realize, whereby the control circuits via at least two independent multi-way valves acted upon by the rules.
