Applied Functions
6-7 Torque Limit Switching
The function switches the torque limit by the operation directions, and depending on the
Forward External Torque Limit (PCL), the Reverse External Torque Limit (NCL), and the
Forward/Reverse Torque Limit Input Commands from the MECHATROLINK-II
communications.
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.
The Torque Limit Selection (Pn521) is used to select a method to switch the torque limit.
Operating Conditions
The torque limit switching function works under the following conditions.
