<P>PROBLEM TO BE SOLVED: To properly evaluate a power consumption amount and a regeneration power amount in a machine system of a power supply constitution having a plurality of amplifier groups. <P>SOLUTION: The drive control device of a servomotor of the machine system having a common power supply connected to a host power supply, a plurality of power feeding parts for feeding power to the servomotor from the common power supply, and the plurality of amplifier groups each constituted of these items has an amplifier group power detection part for obtaining the power amount at each amplifier group. Each amplifier group power detection part sums an individual periodical power amount dEak with respect to the servomotor connected to the power feeding part belonging to the corresponding amplifier group, obtains an amplifier group periodical power amount dEbg which is the power consumption amount or the regeneration power amount in the amplifier group, and obtains an amplifier group power consumption amount Ebng by integrating it for a prescribed period of time. The individual periodic power amount dEak is a positive value when the servomotor consumes power, and a negative value when the servomotor regenerates power. <P>COPYRIGHT: (C)2010,JPO&INPIT |
