SYNCHRONOUS DRIVING DEVICE OF POSITION DECISION MODULE

摘要

PURPOSE: A synchronous driving device of a position decision module is provided to perform a synchronous driving operation by using an independent position decision IC to control an external driving approval signal and a synchronous driving signal. CONSTITUTION: A synchronous driving device(10) of a position decision module includes a plurality of AND gates(G1-G3), a NOR gate(G4), and an external synchronous driving input pin. The AND gates(G1-G3) are used for multiplying an axis driving signal inverted by an inverter by an axis external-driving approval signal corresponding to the axis driving signal and outputting the multiplied value. The NOR gate(G4) is used for outputting an external synchronous driving signal by calculating the sum of the output signals of the AND gates(G1-G3) and inverting the result. The external synchronous driving input pin is used for receiving the external synchronous driving signal from the outside.
