    • A servo amplifier for a robot capable of avoiding an excessive capacity for dealing with a regenerative power to achieve downsizing, cost reduction and energy saving of the device. A servo amplifier for driving servomotors of a robot to perform an operation using an electric power from a power source. The servo amplifier comprises a changeable converter connected with the power source and a plurality of inverters electrically connected with the converter and the servomotors. The changeable converter is selectively provided as a converter having a regenerative function of returning a regenerative power generated in the servomotors to the power source, or a converter having a regenerative function of discharging the regenerative power through a resistor, depending on conditions of the operation by the robot.

    • Selected switching devices (e.g., Tra and Trd) of an inverter are turned on to supply a current between selected phases. If the respective inclinations of current waveforms then detected by current detection circuits IR and IS are equal to a reference inclination, it can be concluded that the current detection circuit in a circuit through which the current then flows, switching devices, and motor windings are normal. If the inclinations of the detected current waveforms are "0" or smaller than the reference, it can be concluded that the current detection circuits, switching devices, or motor windings are abnormal. In such a case, an abnormal spot is identified by checking the inclinations of the waveforms of the current detection circuits in like manner after changing the switching device to be turned on. If the inclinations of the detected current waveforms are very much greater than the reference, cables or motor windings can be concluded to be shorted.
