Power Supply Check From Extension Power Supply Module (Current Consumption Calculation) - Mitsubishi Electric MELSEC iQ-F Series User Manual

Power supply check from extension power supply module
(current consumption calculation)
If the maximum number of CPU modules that can be connected is exceeded and further expansion modules are connected,
add an extension power supply module.
Check if power can be supplied to extension modules with the power supply capacity of the extension power supply module.
