Torque limit selection
The torque limit can be selected using TL (External torque limit selection).
In addition, by turning on TL1 (Internal torque limit selection) through servo parameters, [Pr. PC35 Internal torque limit 2] can
be selected.
However, if the value for [Pr. PA11] or [Pr. PA12] is less than the limit value selected using TL/TL1, the value for [Pr. PA11] or
[Pr. PA12] is enabled.

Checking "Limiting torque" status
TLC (Limiting torque) turns on when the servo motor torque reaches the torque that was limited by the forward rotation torque
limit, reverse rotation torque limit, internal torque limit, or analog torque limit.
