Torque limit function
The "torque limit function" limits the generated torque to a value within the "torque limit value" setting range when the torque
generated in the servomotor exceeds the "torque limit value".
The "torque limit function" protects the deceleration function, limits the power of the operation pressing against the stopper,
etc. It controls the operation so that unnecessary force is not applied to the load and machine.
Relation between the torque limit function and various controls
The following table shows the relation of the "torque limit function" and various controls.
: Set when required (Set to " " when not used.)
: Setting not required (Use the initial value or a value within the setting range.)

function
"[Pr.17] Torque limit setting value"
or
"[Cd.101] Torque output setting value".
After the "[Pr.47] Creep speed" is reached,
this value becomes the "[Pr.54] Home
position return torque limit value".
"[Pr.17] Torque limit setting value"
or
"[Cd.101] Torque output setting value".
Setting value is invalid.
"[Pr.17] Torque limit setting value"
or
"[Cd.101] Torque output setting value".
Torque limit value is continued after control
mode switching.
