Zusammenfassung: | PURPOSE:To simplify a circuit configuration by controlling a voltage or current supplied to the brake and the clutch by the combination of resistors connected in series with a brake and a clutch. CONSTITUTION:When the inputs of drivers 62-65 or low, a current is not flowed to input light emitting diodes of photocouplers 32-35. Thus, the output transistors of the photocouplers 32-35 and the transistors 12-15 are interrupted. Thus, resistors 2-5 are connected in series with a brake 1. On the other hand, when the inputs of the drivers 62-65 are high, a current is flowed to the input light emitting diodes of the photocouplers 32-35. Thus, the output transistors of the photocouplers 32-35 and the transistors 12-15 are conducted. Therefore, the resistors 2-5 are shortcircuited. The input lines of the drivers 62-65 are connected through the interface circuit such as a latch circuit with the data bus of a computer. |
