4.6

Torque limit

The torque limit function limits the torque generated by the servo motor.
The following torque limit can be set.

 • When setting the torque above the maximum torque of the servo motor, the torque is limited by the 

maximum torque of the servo motor.

 • Servo parameters that are mapped to an object from the controller will overwrite those written from the 

engineering tool. 

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 "0.0" is set, no torque is generated.

Setting method

Servo parameter setting

The maximum torque is always limited by the value of [Pr. PA11 Forward rotation torque limit] and [Pr. PA12 Reverse rotation 
torque limit] during operation.
Set the rated torque at 100.0 [%].

Relation between servo parameters and objects

[Pr. PA11] and [Pr. PA12] is used for [Positive torque limit value (Obj. 60E0h)] or [Negative torque limit value (Obj. 60E1h)].
For [Pr. PA14 Travel direction selection] and [Pr. PC29 POL reflection selection at torque mode ], the relationship between 
objects and servo parameters that limit the torque changes as follows.
