5.19.10 Speed Limit during Torque Control
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.
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.
Pn408
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).
• Rotary Servomotors
Pn407
• Linear Servomotors
Pn480
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 OW0E (Speed Limit for Torque/Force Reference).
Refer to the following manual for details.
