7-8 Torque Limit Switching
This function switches the torque limit according to the operation direction, and depending on the Posi-
tive Torque Limit (PCL), the Negative Torque Limit (NCL), and the Positive/Negative 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 is suppressed to protect mechanical systems,
etc.
The Torque Limit - Switching Selection (3330-01 hex) is used to select a method to switch the torque
limit.
The torque limit switching function is enabled under the following conditions.
• Position control, velocity control, and torque control
• The Servo is ON.
