Mass [kg] 1.5 2.0
Note 1. 0.35 A 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. Reusable regenerative energy corresponds to energy generated under the following conditions.
Rotary servo motor: Regenerative energy is generated when the machine, whose moment of inertia is equivalent to the
permissible charging amount, decelerates from the rated speed to stop.
Linear servo motor: Regenerative energy is generated when the machine, whose mass is equivalent to the permissible
charging amount, decelerates from the maximum speed to stop.
Direct drive motor: Regenerative energy is generated when the machine, whose moment of inertia is equivalent to the
permissible charging amount, decelerates from the rated speed to stop.
3. Moment of inertia when the motor decelerates from the rated speed to stop
Moment of inertia for two axes when two motors decelerate simultaneously
Moment of inertia for each axis when multiple motors do not decelerate simultaneously
The values also apply to the direct drive motor.
4. Mass when the machine decelerates from the maximum speed to stop
The primary-side (coil) mass is included.
Mass for two axes when two motors decelerate simultaneously
Mass for each axis when multiple motors do not decelerate simultaneously
5. Test pulse is a signal which instantaneously turns off a signal to the servo amplifier at a constant period for external circuit to
self-diagnose.
6. The load-side encoder is compatible only with two-wire type communication method. Not compatible with pulse train interface
(A/B/Z-phase differential output type).
7. STO is common for all axes.
8. Fully closed loop control is compatible with the servo amplifiers with software version A3 or later.
Check the software version of the servo amplifier using MR Configurator2.
9. The command communication cycle depends on the controller specifications and the number of axes connected.
10. The scale measurement function is available for the MR-J4W2-_B servo amplifiers of software version A8 or later. Check the
software version of the servo amplifier using MR Configurator2.
11. This value is applicable when a 3-phase power supply is used.
