FIELD: engines and pumps.SUBSTANCE: invention relates to ACS and can be used in programmable discrete drive motor. Claimed device comprises the main four cycle reversible pulse distributor for control over stepped motor including two-digit reversible binary counter. Clock, permit and count direction inputs of the latter are connected to appropriate clock pulse, control and reverse buses. The latter are group inputs of said distributor. Besides, it comprises two inverters and XOR elements. Note here that additionally this device incorporates 1and 2standby distributors, unit of majority gates, 1and 2sets of XOR of fault address detection unit. First outputs of the main and standby distributors are connected to 1?3inputs of 1majority gate. Second outputs of the main and standby distributors are connected to 1?3inputs of 2majority gate. Third distributor outputs are connected to 1?3inputs of 3majority gate. Third distributor outputs are connected to 1?3inputs of 3majority gate. Outputs of majority gates are connected via power amplifiers to windings of stepped motor to make the 1group output of the device. 1and 2output of fault address detection unit group are connected to 1?3outputs of the main and standby distributors.EFFECT: expanded operating performances, higher reliability, simplified operation.3 tbl, 1 dwg |
