<P>PROBLEM TO BE SOLVED: To provide a motor controller having a function of displaying or outputting the loss of a power line. <P>SOLUTION: The motor controller 10 performs drive control of motors by providing a command, based on the current detection values detected by ammeters 18-1 to 18-n, which detect currents flowing through the motors, and a current command value for driving the motors to a power supply unit having inverters 14-1 through 14-n, which convert DC power into AC power for supply to motors 16-1 through 16-n for machine tools or for industrial machines, and includes a loss calculation unit which calculates the loss values of power lines 20-1 through 20-n between the motors and the inverters, preset in the memory of the motor controller 10, and either a display unit which displays the loss values calculated by the loss calculating unit or an output unit which outputs the loss values to an external apparatus of a motor control unit. <P>COPYRIGHT: (C)2011,JPO&INPIT |
