Applied Functions
6-8 Torque Limit
Outline of Operation
 The output torque by the Servomotor can be limited.
 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 the 
mechanical system, etc.
 Various methods are available according to Torque Control Selection (Pn521).
