Selecting the Speed Limit
The smaller of the external speed limit and internal speed limit will be used.
Internal Speed Limiting
Set the speed limit for the motor in Pn407 (Speed Limit during Torque Control) or Pn480
(Speed Limit during Force Control).
Also set Pn408 = n.
X
(Speed Limit Selection) to specify using the maximum motor speed
or the overspeed alarm detection speed as the speed limit. Select the overspeed alarm detec-
tion speed to limit the speed to the equivalent of the maximum motor speed.
Note: If you are using a Rotary Servomotor, set Pn407 (Speed Limit during Torque Control). If you are using a Linear
Servomotor, set Pn480 (Speed Limit during Force Control).

Linear Servomotors
Note: If the parameter setting exceeds the maximum speed of the Servomotor, the Servomotor’s maximum speed
or the overspeed alarm detection speed will be used.
External Speed Limiting
The motor speed will be limited by VLIM (Limit Speed for Torque Control). Refer to the following
manual for details.
