6-8-1 Outline of the Function
6-8 Torque Limit
• The torque limit function limits the output torque of the Servomotor.
• This function is used in the following conditions.
• When push-motion operation, such as pressing, is performed.
• When the torque at startup and during deceleration should be suppressed to protect mechanical
systems, etc.
• Various torque limit options can be set in Torque Limit Selection (Pn521).
• When torque feed-forward is selected, the torque limit function is enabled only during speed control
when the set value is 1 to 3.
