Short cut positioning circuit of selecting point

Abstract

Abstract PURPOSE:To turn an object to be controlled to a commanded position with short cut, by driving the object to be controlled at a relay group having three contacts and a circuit selecting right or left turning with the turning command. CONSTITUTION:A drive circuit 2, a stop circuit 3 and right and left turning selecting circuits 4, 5 are operated interlockingly mutually with a relay group and relays CR1-5 operated with 6 command contacts (not shown). The relay group each has three contacts RY1A-C,...RY6A-C, and connected to 6 contacts k1-6...m1-6 of rotary switches RT1-3. When a command is given from the 1st position (shown in Figure) to the 5th position, the contacts RY5A-C are closed and the RY1A-C are opened, the relay CR3 is opened and the CR5 is closed. The relay CR5 is excited via contacts V3, m5 and the contact RY5C, the contact CR5K is closed to excite the relay CR2 and the contact 2R2A is closed and self-held to drive left the object. Thus, the short cut is selected automatically with sector type contacts V3, V4 as shown in the previous example.
