The speed of movement along the coordinates is controlled by an arrow instrument. In this case, it is possible to automatically signal an excess of the magnitude of the speed and acceleration relative to that set by the switch.

Claims

programs 1 logical block 2, registration block 3, feedback node n movement 4, switch 5 and display unit 6. Block 1 consists of a tape-reading device 7, a decoder 8, a reference channel amplifier 9, and encoders 10 and control channel amplifiers 11. Block 2 consists of recalculated modules 12. Assembly 4 includes pulse formers 13 and differentiating unit 14. The device operates as follows. Node 7 reads a phase pulse signal from a magnetic tape over several channels. In the decoder 8 and 10 of the corresponding channel, a predetermined phase division algorithm is generated, for example 7:11, when seven negative signals follow each positive pulse. In each channel, the specified algorithm is monitored by a scaling module 12, at the output of the second one, when a failure occurs, the potential of the voltage is detected by block 3, for example, by a light and sound signal. The initial start-up of module 12 is effected by a pulse from the output of blocks 3. According to the indications of the indication block b, zero geometric information in the program is monitored, as well as the speed characteristics of the program. Thus, the recording quality of a phase-pulse signal on a magnetic tape is monitored. In this case, the functions of the feedback feedback sensor are performed by the differentiating unit 14. The transfer function of such a static feedback link corresponds to the static transfer function of the feedback sensor of the inductosyn type. Pulse shapers 13 lashes; | adjust the phase of the feedback signal. The operation mode of the electronic control units 1 is controlled by block 3 and the display unit 6. The operating mode of the display unit 6 is set by switch 5. The device operates in two modes of quality control check, tape recording (a set of reference electronic components is used in block 1 of program playback) and checks electronic components included in block 1 (using the standard test program on a magnetic tape). The device allows improving the quality of control programs issued to the machine, as well as reducing the time of a simple machine during the repair of electro-HHJJX nodes in the program playback unit.
