Abstract

PURPOSE:To improve operation efficiency, by constituting a control circuit for detecting the amount of load with a programable controller. CONSTITUTION:When the speed of motor is lower than a base speed, a speed command NA inputted to a programable controller 40 is employed as it is as a speed command Nc. When the rotary speed N of a motor 1 reaches the base speed, a gate 51 is turned ON to input digital armature current Ia' to an average value processing circuit 52. The average armature current Ia'' is substituted with an increment speed rotation in a function simulating circuit 53 then converted through an inclined signal generating circuit 54 into an inclined speed command NE. Thereafter, it is added to a digital speed command NA' corresponding to the base speed in a data adding section 55 to produce a speed command Nc. Consequently, operation efficiency can be improved.
