D2 Series Servo Drive User Manual Protection Function
HIWIN MIKROSYSTEM CORP. 8-3
Table8.1.2
Parameter Name Description Default Value
Speed
Set the maximum velocity of
motor during motion
AC servo motor: 3,000 rpm
Acc.
Set the maximum acceleration of
motor during motion
AC servo motor: 1/2 * (Kt * Ip / (10 * Jm))
Dec.
Set the maximum deceleration of
motor during motion
AC servo motor: 1/2 * (Kt * Ip / (10 * Jm))
Dec. kill
Set the deceleration of motor for
emergency stop
AC servo motor: 2 * Acc.
Note:
Jm is the moment of inertia obtained by the inertia estimation.
As shown in figure 8.1.1, the “Motion Protection” area displays the maximum speed, maximum
acceleration, and maximum deceleration of movement. The unit can be set according to the user’s
custom unit by clicking “Position Units”. These settings are not only used for the motion protection,
but also used as test run parameters. Therefore, when the motion function (“P2P”, “Relative move”,
or “Jog”) in the performance center is used, it is important to check whether the data in the “Motion
Protection” area is the user’s motion protection setting, as shown in figure 8.1.2. In the position mode
or velocity mode, be sure to set “Acc.” and “Dec.” to the required value multiplied by 10 times, to
avoid being limited by the motion protection function. If this action is ignored, the desired speed or
acceleration/deceleration may not be achieved when the motion command is sent from the host
controller.
