Note 1. 0.45 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
Direct drive motor: Regenerative energy is generated when the machine, whose moment of inertia is equivalent to the
3. Moment of inertia when the machine decelerates from the rated speed to stop
Moment of inertia for three axes when three 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 three axes when three 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. STO is common for all axes.
7. The command communication cycle depends on the controller specifications and the number of axes connected.
8. Servo amplifier with software version A3 or later is compatible with the command communication cycle of 0.222 ms. However,
note that the following functions are not available when 0.222 ms is used: auto tuning (real time, one-touch, and vibration
suppression control), adaptive filter II, vibration tough drive, and power monitoring.
9. This value is applicable when a 3-phase power supply is used.
10. The safety level depends on the setting value of [Pr. PF18 STO diagnosis error detection time] and whether STO input
diagnosis by TOFB output is performed or not. For details, refer to the Function column of [Pr. PF18] in section 5.2.6.
11. Follow the restrictions in section 2.7 when using this product at altitude exceeding 1000 m and up to 2000 m above sea level.
