Zařízení pro kontrolu rozdílů otáček na kovoobráběcíohstrojích, zejména v lisech s mechanickým pohonem smykadla,přitom jak na straně náhonu, tak na straně poháněného me-chanismu s kontrolovanou hřídeli se otáčejí ovládací ko-touče s obvodovými výstupky a signály ze snímačů pro pře-rušení ovládacího proudu při zlomení hnací hřídele postu-pují na zpracování, vyznačující se tím, že při libovolnévzájemné poloze ovládacích kotoučů (1, 2) a poměru počtuvýstupků menším než 2 : 1 je každému bezkontaktnímu sní-mači (3,4) přiřazen článek odblokování a mazání (5.1, 5.2) a impulzní paměí (6.1, 6.2), přičemž článek odbloko-vání a mazání (5.1, 5.2) jednoho ze snímačů (3, 4) je spo-jen logicky s impulzní pamětí (6.1, 6.2) druhého ze sníma-čů (4, 3) a jak tento článek odblokování a mazání (5.1, 5.2) , tak i tato impulzní paměč (6.2, 6.1) jsou logicky .spojeny s impulzním selektorem (7.1, 7.2), napojeným napaměí poruch (8.1).
  2. 2. Zařízení podle bodu 1, vyznačující se tím, že pro dvou-kanálový systém řízení se impulsnímu selektoru (7.2) přidá-vá přídavná chybová parně t (8.2). 260960
