Sets the torque limit function.
 
• Selects the torque limit switching method.
• When 1 or 2 is set, positive and negative torque limit values vary with state of the torque limit input 
(PCL/NCL) and Controlword (P_CL/N_CL).
• When the maximum torque value is smaller than the other torque limit values, it is used as the limit 
value.
 Description of Set Values
 
• Sets the maximum torque limit value. The function of this object is the same as the Max torque 
(6072 hex). Set this object when you use a limit value without mapping 6072 hex to a PDO.

Subindex 01 hex: Switching Selection
Set value Description
0 Switching by PCL/NCL signal is not allowed. Use the Positive torque limit value and Negative 
torque limit value.
1 Use the Positive Torque Limit Value 2 when both of the torque limit input (PCL) and Control-
word (P_CL) are OFF, and the Positive Torque Limit Value for the other combinations.
If both the torque limit input (NCL) and Controlword (N_CL) are OFF, the Negative torque limit 
value 2 is used. In other cases, the Negative torque limit value is used. 
2 Use the Positive Torque Limit Value when both of the torque limit input (PCL) and Controlword 
(P_CL) are OFF, and the Positive Torque Limit Value 2 for the other combinations.
If both the torque limit input (NCL) and Controlword (N_CL) are OFF, the Negative torque limit 
value is used. In other cases, the Negative torque limit value 2 is used.
