10.3.2 The dynamic brake at the load inertia moment
Use the dynamic brake under the load inertia moment ratio indicated in the following table. If the load inertia
moment is higher than this value, the built-in dynamic brake may burn. If there is a possibility that the load
inertia moment may exceed the value, contact Mitsubishi.
The values of the load inertia moment ratio in the table are the values at the maximum rotation speed of the
servo motor.

10.5 Inrush currents at power-on of main circuit and control circuit
The following table indicates the inrush currents (reference data) that will flow when the maximum permissible
voltage (200V class: 253VAC, 400V class: 528VAC) is applied at the power supply capacity of 2500kVA and
the wiring length of 1m (3.28ft).

Since large inrush currents flow in the power supplies, always use no-fuse breakers and magnetic contactors.
(Refer to section 11.12.)
When circuit protectors are used, it is recommended to use the inertia delay type that will not be tripped by an
inrush current.

11. OPTIONS AND AUXILIARY EQUIPMENT
11. OPTIONS AND AUXILIARY EQUIPMENT
WARNING
Before connecting any option or peripheral equipment, turn off the power and wait
for 15 minutes or more until the charge lamp turns off. Then, confirm that the
voltage between P(
) and N( ) is safe with a voltage tester and others.
Otherwise, an electric shock may occur. In addition, always confirm from the front
of the servo amplifier whether the charge lamp is off or not.
CAUTION
Use the specified auxiliary equipment and options. Unspecified ones may lead to a
fault or fire.
11.1 Cable/connector sets
POINT
Protective structure indicated for cables and connecters is for a cable or
connector alone. When the cables and connectors are used to connect the
servo amplifier and servo motor, and if protective structures of the servo
amplifier and servo motor are lower than that of the cable and connector,
specifications of the servo amplifier and servo motor apply.
As the cables and connectors used with this servo, purchase the options indicated in this section.
