13.3 Notes
Take note of the following points if you are using a high acceleration/deceleration type:
(1) Keep the duty within 50%. If the duty exceeds 50%, an overload error may occur.
(2) The maximum loading capacity follows the applicable value specified in the table under “Specifications
of High Acceleration/Deceleration Actuators” regardless of the acceleration setting.
(3) Refer to p. 24 for the maximum speed.

*1
When the power is turned on, rush current corresponding to around 5 to 12 times the rated current
will flow for approx. 1 to 2 msec. Take note that the specific level of rush current varies depending on
the impedance of the power-supply line.
*2
The current becomes the greatest during the detection of excited servo-motor phase, which is
performed when the servo is turned on for the first time following the power on.
(Normal: 1 to 2 seconds / Maximum: 10 seconds)
The applicable controllers vary depending on the actuator specification. Check the model of the actuator
you will be using.
