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 10VDC
across TLA-LG. Connect the positive terminal of the power supply
to TLA. Maximum torque is generated at 10V. (Refer to section
3.4.1 (5)) Resolution:10bit Analog
input
Analog torque
command TC
CN1B
12
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 section 3.4.3 (1))
The torque at 8V input can be changed using parameter No. 26. Analog
