Note 1. 0.25A is the value applicable when all I/O signals are used. The current capacity can be decreased by reducing the number of I/O
points.
2. When closely mounting MR-J3W-44B, operate them at 90
3. The regenerative energy is generated under the following conditions.
Rotary servo motor: The energy is generated when a machine with the inertia moment equivalent to permissible charging amount
Linear servo motor: The energy is generated when a machine with the mass equivalent to permissible charging amount decelerates
Direct drive motor: The energy is generated when a machine with the inertia moment equivalent to permissible charging amount
4. This value is inertia moment when decelerating rotary servo motor from the rated speed to a stop. When decelerating two axes
simultaneously, the inertia moment is a total of two axes. When not decelerating two axes simultaneously, the inertia moment is for
one axis. This note also applies to the direct drive motor.
5. This value is mass when decelerating linear servo motor from the rated speed to a stop. The mass includes a mass of primary side
(coil). When decelerating two axes simultaneously, the mass is a total of two axes. When not decelerating two axes simultaneously,
the mass is for one axis.
