10. CHARACTERISTICS
10 - 12
10.5 Inrush currents at power-on of main circuit and control circuit
POINT
The inrush current values can change depending on frequency of turning on/off
the power and ambient temperature.
The following shows the inrush currents (reference data) that will flow when 240 V AC (MR-J4-_A(-RJ) servo
amplifier) or 480 V AC (MR-J4-_A4(-RJ) servo amplifier) 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-
J4-70A(-RJ), the inrush currents of the main circuit power supply are the same.

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.
