In the torque mode, this group of parameters is used to set the value of the internal
speed limit. We can select which parameter gives out the internal speed limit through
the speed limit selection terminal (SC1 and SC2). The corresponding relationships are
listed in the table above. Please note that the magnitude of the speed limit is the
absolute value of the corresponding parameter, the direction of it is the same as that of
the torque command.

T
This parameter is used to set the internal torque setting. Taking the rated torque of the
servo motor as 100%, this setting is the percentage of the rated torque of the servo
motor. In the torque mode, if the absolute value of this parameter is larger than the max
torque limit (PA.14), the magnitude of the output torque is the setting value of PA.14,
and the direction is the same as that of the parameter.

P.S
In the speed and position modes, this parameter is used to set the value of internal
torque limit. Taking the rated torque of the servo motor as 100%, this setting is the
percentage of the rated torque of the servo motor. In the speed and position modes, we
can select whether the torque limit is the internal torque limit or external analog torque
limit through the torque limit selection terminal (TQC). See chapter 4.5.8.3 for details.
