This is the net value at the rated load.
When using a 400V class power supply, turn the power supply ON and OFF at the
primary side of the voltage conversion transformer.
Note: Transformer inductance will cause a surge voltage if the power is turned ON and OFF at the
secondary, damaging the servo amplifier.
