Torque limit [A]
The torque limit function limits the torque generated by the servo motor.
The following torque limit can be set. The torque limit function can be used by switching the following limit vales.
Item
Internal torque limit
Internal torque limit 2
External analog torque limit
• When setting the torque above the maximum torque of the servo motor, the torque is limited by the
maximum torque of the servo motor.
• Analog torque limit cannot be used during torque control mode.
Precautions
• If the torque limit is canceled during servo-lock, the servo motor may suddenly rotate, depending on the amount of the
position deviation from the command position.
• When using the torque limit, check that [Pr. PB06 Load to motor inertia ratio/load to motor mass ratio] is set properly.
Improper settings may cause an unexpected operation such as an overshoot.
• When [Pr. PA11 Forward rotation torque limit] and [Pr. PA12 Reverse rotation torque limit] are set to "0.0", no torque or
thrust is generated.

Outline
The maximum torque is limited by the values of [Pr. PA11 Forward rotation torque limit] and [Pr.
PA12 Reverse rotation torque limit].
The generated torque is limited by the value of [Pr. PC35 Internal torque limit 2].
The maximum torque is limited by the value input to the TLA (analog torque limit).
