Internal Speed Limit Function

If the internal speed limit function is selected in Pn002.1, set the limit of the maximum speed of the servomo-
tor in Pn480. The limit of the speed in Pn408.1 can be either the maximum speed of the servomotor or the

overspeed alarm detection speed. Select the overspeed alarm detection speed to limit the speed to the maxi-

mum speed of the servomotor or the equivalent.

Note: The servomotor’s maximum speed or the overspeed alarm detection speed will be used when the setting in this

parameter exceeds the maximum speed of the servomotor used.

External Speed Limit Function

If the external speed limit function is selected in Pn002.1, the motor speed is controlled by the speed limit
value (VLIM). For details, refer to

-V Series User’s Manual, MECHATROLINK-III Standard Servo Profile
