Analog torque
limit TLA To use this signal in the speed control mode, set any of
parameters No. 43 to 48 to make TL available.
When the analog torque limit (TLA) is valid, torque is limited in
the full servo motor output torque range. Apply 0 to +10 VDC
across TLA-LG. Connect the positive terminal of the power supply
to TLA. Maximum torque is generated at +10 V. (Refer to (2) in
Section 3.4.1.)

Used to control torque in the full servo motor output torque
range.
Apply 0 to ±8VDC across TC-LG. Maximum torque is generated at
±8V. (Refer to (1) in Section 3.4.3.)
The torque generated at ±8V input can be changed using
parameter No. 26.
