Power supply measurement control circuit and robot controller

The invention provides a power supply measurement control circuit capable of monitoring an external AC power supply supplying power for driving an industrial robot and detecting an abnormality of the AC power supply. The power supply measurement control circuit is provided with: an AC current detection unit (21) and an AC voltage detection unit (22) that are located between an AC power supply (10) and a main circuit relay (23) that supplies or interrupts power supplied to the robot, and that respectively detect the current waveform and voltage waveform of AC power from the AC power supply (10); a detection processing unit (40) provided with a detection storage unit (41) that stores the detected current waveform and voltage waveform and calculates a current and a voltage on the basis of the current waveform and the voltage waveform; and an abnormality detection unit (46) that is connected to the detection processing unit (40) so as to detect an abnormality in the AC power supply (10). 本发明提供一种电源测量控制电路，其能够监视供给用于
