Note 1. Initial value is the 48 V DC. For 24 V DC, set [Pr. PC05] to "_ 1 _ _". The characteristics of the servo motor vary depending on
whether 48 V DC or 24 V DC is used. For details, refer to "Servo Motor Instruction Manual (Vol. 3)".
2. 0.25 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.
3. This is an electronic dynamic brake. This will not operate during control circuit power supply off. In addition, It may not operate
depending on the contents of alarms and warnings. Refer to chapter 8 for details.
4. The communication cycle depends on the controller specifications and the number of axes connected.
5. When closely mounting the servo amplifiers, operate them at the ambient temperatures of 45 ˚ C or lower, or the total effective
load ratio of 45 w or lower for the two axes.
6. 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.
7. This is moment of inertia when the motor decelerates from the rated speed to stop. This will be moment of inertia for two axes
when two motors decelerate simultaneously. And this will be moment of inertia for each axis when multiple motors do not
decelerate simultaneously.
