10.5 Inrush currents at power-on of main circuit and control circuit
POINT
For a servo amplifier of 600 W or less, the inrush current values can change
depending on frequency of turning on/off the power and ambient temperature.
Since large inrush currents flow in the power supplies, always use molded-case circuit breakers and
magnetic contactors. (Refer to section 11.10.)
When circuit protectors are used, it is recommended that the inertia delay type, which is not tripped by an
inrush current, be used.
(1) 200 V class
The following shows the inrush currents (reference data) that will flow when 240 V AC is applied at the
power supply capacity of 2500 kVA and the wiring length of 1 m. When you use a 1-phase 200 V AC
power supply with MR-J4-10A(-RJ) to MR-J4-200A(-RJ), the inrush currents of the main circuit power
supply are the same.
