7-7 Torque Limit Switching
This function switches the torque limit according to the operation direction, and depending on the
Forward External Torque Limit (PCL), the Reverse External Torque Limit (NCL), and the Forward/
Reverse Torque Limit Input Commands from EtherCAT 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 (3521 hex) is used to select a method to switch the torque limit.
The torque limit switching function works under the following conditions.
