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.
A molded-case circuit breaker and magnetic contactor may fail or malfunction due to an inrush current
flowing through the servo amplifier's power lines (input lines) at power on. Therefore, use products with the
specifications as described. (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 servo amplifier) is
applied at the power supply capacity. Even when you use a 1-phase 200 V AC power supply with MR-
J4-10B(-RJ) to MR-J4-200B(-RJ), the inrush currents of the main circuit power supply is the same.
