Abstract

PURPOSE: To provide multi-speed control with a single speed controller, by comparing a frequency dividing pulse from a variable frequency divider with a speed reference pulse corresponding to the said frequency dividing pulse and controlling the speed of a servomotor by virtue of the differential output.
CONSTITUTION: When feed mode signals LS, MS, HS from a line printer controller are set, a variable frequency divider 21 for dividing an encoder pulse through a sensor amplifier 7 divides the encoder pulse into one, two and three divisions. A speed controller 22 compares the output of the variable frequency divider 21, that is, intervals of divided encoder pulses with a reference pulse from a speed reference pulse generator 23. A servomotor controller 24 puts out signal to the speed controller 22 until it reaches a jump position and encoder pulses to a motor 4 in case of positioning control.
