Patent EP-0454853-A1 (EP)
Inventor: MATSUBARA SHUNSUKE - FANUC MAN
IPC: G05B19/23
Filed: 1990-10-15
Abstract: Procédé de commande de position de réaction permettant d'effectuer aisément et de manière appropriée une commande de position dans différentes installations mécaniques. Un convertisseur de comptage d'impulsions (5) calcule la somme du produit du nombre (xn) d'impulsions de réaction délivrées par un codeur d'impulsions (4) pendant une période déterminée, ainsi qu'un premier coefficient de conversion (A) et le reste (Rn - 1) pendant la période précédente (S1 ~ S3). Si la somme est positive ou nulle, il produit autant d'impulsions de réaction qu'un quotient (yn') que l'on obtient en divisant la valeur absolue de la somme par un deuxième coefficient de conversion (B), et le reste (Rn') résultant de la division est stocké en tant que reste (Rn) afin d'obtenir une somme pendant la période suivante (S4 ~ S8). Si la somme est négative, le nombre d'impulsions de réaction de position est fixé à une valeur (-yn' - 1) que l'on obtient en inversant le signe du quotient et en soustrayant 1 de la valeur résultante, et une valeur (B - Rn') que l'on obtient en soustrayant le reste du deuxième coefficient de conversion est utilisée comme reste (S9, S10). La pondération d'une seule impulsion de réaction de position est égale à une distance de déplacement d'une pièce mécanique mobile par impulsion d'instruction de position, et la commande de position dans différentes installations peut être effectuée par un seul type de codeur d'impulsions.

Abstract: According to this invention, a well region (17) is formed on a semiconductor substrate (11). An n⁺-type first semiconductor region (12) is formed in the well region (17), and an input pad (18) for receiving an external signal is connected near the first semiconductor region (12). This input pad (18) is connected to an input circuit (IN) of an integrated circuit constituted by an inverter circuit and to an external terminal (16) for receiving an external signal. N⁺-type second semiconductor regions (13, 14) are formed in the well region (17) located on both the sides of the first semiconductor region (12). A ground potential (Vss) is applied to these second semiconductor regions (13, 14). A p⁺-type third semiconductor region (15) is formed around these second semiconductor regions (13, 14) in the well region (17). The ground potential (Vss) is applied to the third semiconductor region (15). Therefore, a parallel circuit formed by a parasitic transistor (19) and a parasitic diode (10) is formed between the input pad (18) and the ground potential (Vss). The parasitic transistor (19) is turned on upon electrostatic discharge, and the parasitic diode (10) is turned on when a negative potential (V IL ) for test is applied to the input pad (18), thereby preventing an erroneous operation of a transistor arranged on the semiconductor substrate (11).
