Title:
MODULATION PULSE GENERATOR
Document Type and Number:
Japanese Patent JPS6192197
Kind Code:
A
Abstract:
PURPOSE:To efficiently control the entire generator with less load of a controller by outputting control pulse number necessary for a device to be controlled by the start addressing of the first recording means by a corresponding mode. CONSTITUTION:A pulse train having various periods necessary to control 4-phase pulse motor is written and set in a memory 17 in advance. A controller 1 sets the start address for reading the memory 17 in a register 12, and the stop address for reading the memory 17 in a register 13. A gate signal from a start/ stop controller 9 is output to an address counter 16, the memory 17, a counter 18 and an output circuit 19 to turn ON them. The pulse of the period is output to the circuit 19 in response to the period stored in the address in the memory 17 to drive a pulse motor.
