The present disclosure takes account of such problems in the background art, and an object thereof is to provide a power supply control device and a power supply control method of a component supply device capable of enabling efficient changeover work of tape feeders by making sufficient use of output current capacity of the power supply within a range in which excess current does not occur.
A power supply control device of a component supply device of the present disclosure that solves the above problems is a device for controlling a consumption current supplied from a power supply device to a tape feeder loaded on the component supply device, the component supply device being exchangeably loaded with multiple of the tape feeders to which the consumption current is supplied and that perform a specified operation, the power supply control device including: a consumption current acquiring section configured to acquire the consumption current corresponding to a state of the multiple tape feeders loaded on the component supply device, based on a measured value or a design value; a total consumption current calculating section configured to calculate a total consumption current that is a total of each of the consumption currents corresponding to the multiple tape feeders; and an operation controlling section configured to control the specified operation of the multiple tape feeders within a range in which the total consumption current does not exceed an output current capacity of the power supply device.
