Selecting the Speed Limit
The smaller of the external speed limit and internal speed limit will be used.
Parameter
 
n. 0 Reserved setting (Do not use.)
Use the speed limit from the VLIM (Limit

 
n. 1
Speed for Torque Control) command as the
(default setting)
speed limit. (Use external speed limiting.)
 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).

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
