6.6 Internal Torque Limits
6-22
6.6
Internal Torque Limits
You can limit the torque that is output by the Servomotor.
If you use internal torque limits, the maximum output torque will always be limited to the speci-
fied forward torque limit (Pn402) and reverse torque limit (Pn403).
Note: If you set a value that exceeds the maximum torque of the Servomotor, the torque will be limited to the maxi-
mum torque of the Servomotor.
•
Rotary Servomotors
*
Set a percentage of the rated motor torque.
Note: If the setting of Pn402 or Pn403 is too low, the torque may be insufficient for acceleration or deceleration of
the Servomotor.
•
Linear Servomotors
*
Set a percentage of the rated motor force.
Note: If the setting of Pn483 or Pn484 is too low, the force may be insufficient for acceleration or deceleration of the
Servomotor.
