6.14.8 Detection of output torque (TU signal, Pr. 864)
Output the signal when the motor torque rises above the setting value. This function can be
used for electromagnetic brake operation, open signal, etc.
When the output torque reaches or exceeds the detected torque value set in Pr. 864 under real
sensorless vector control, advanced magnetic flux vector control or vector control, the torque
detection signal (TU) turns on.It turns off when the torque falls below the detection torque value.
For the TU signal, set "35 (source logic) or 135 (sink logic)" in Pr. 190 to Pr. 196 (output terminal
function selection) and assign functions to the output terminal.
