Notes: 1. Rated output and speed of a servo motor are applicable when the servo amplifier, combined with the servo motor, is operated within the specified power supply voltage.
2. The reusable regenerative energy is the energy generated when a machine, which has a moment of inertia equivalent to the permissible charging amount, decelerates
from the rated speed to a stop.
3. The permissible charging amount is equivalent to the moment of inertia when the servo motor decelerates from the rated speed to a stop. When two axes are
simultaneously decelerated, the permissible charging amount is equivalent to the total moments of inertia of the two axes. Otherwise, the permissible charging amount is
equivalent to the moment of inertia of each axis.
4. Set [Pr. Po04] to "1 _ _ _" to use 24 V DC.
5. 0.25 A is the value when all of the input/output points are used. The current capacity can be stepped down according to the number of input/output points.
6. The dynamic brake is electronic. The electronic dynamic brake does not operate when the control circuit power is off. It may not operate depending on the alarms and the
warnings. Refer to "MR-J3W-0303BN6 MR-J3W-
B Servo Amplifier Instruction Manual" for details.
7. When using the dynamic brake, refer to "MR-J3W-0303BN6 MR-J3W-
B Servo Amplifier Instruction Manual" for the permissible load to motor inertia ratio.
8. When the servo amplifiers are closely mounted, keep the ambient temperature within 0 °C to 45 °C, and use them with 75% or less of the effective load rate.
