(54) | Motor controlling system for individual-spindle-drive type textile machine |
(57) The present invention relates to a motor controlling system for an individual-spindle-drive
type textile machine and eliminates the need to provide each of the motor controllers
with a memory backup function for set values required to control motors, the motor
controllers each controlling a corresponding driving motor for each processing unit
of the textile machine. Motor controllers 30 each control a corresponding one of driving
motors 2, and a master controller 40 solely controls all the motor controllers 30.
A microcomputer 41 of the master controller 40 has a memory 43 always retaining set
values. When the master controller 40 is activated and when it receives a predetermined
signal from any of the motor controllers 30, the master controller 40 transmits the
corresponding set values retained in the memory 43, to the motor controller 30, which
then stores the values in a memory of a microcomputer 31 (Fig. 1). |
