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 (1)(a) in Section
15.2.5.) Resolution:10bit

TC
CN1-2
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 (2)(a) in Section 15.2.5.)
The torque at
8V input can be changed using parameter No. 26.
