7. A system of analogue-digital position control of electrical drives, particularly of machine tools, containing a position sensor, an analogue-digital converter, a data processing block and drive movement executing systems, characterised in that a variable resistance sensor (1) whose one terminal is permanently connected with a positioned element (3), and a signal output (A) from the sensor (1) is connected with an input (B) of the analogue-digital converter (2) whose output (C) is connected with an information input (D) of the data processing block (5), which block has another information input (E) connected with an output (F) of the data input block (6), and signal outputs (H, I, J) of the data processing block (5) are connected with an input (K, L, M) of the drive control block (7), which block is connected with a drive control motor (8). |
