PURPOSE:To provide a high speed pulse output circuit that is inexpensively constituted and preventsan increase in the cost of motor driver control equipment itself. CONSTITUTION:CW pulses and CCW pulses are applied to a high speed type photocoupler 10. A CW direction select command to command motor forward rotation and a CCW direction select command to command motor reverse rotation are delivered to ordinary low speed type photocouplers 11 and 12, respectively. The CM pulses output from the high speed photocoupler 10 are taken through a first transistor 15 that is driven by the output of the low speed photocoupler 11; the CCW pulses output from the high speed photocoupler 10 are taken through a second transistor 16 that is driven by the output of the low speed photocoupler 12. These pulses are output through first and second output transistors 19 and 20, respectively. |
