If the motor torque which reaches a specific value is detected, the relative signal is output.
The signal is useful for applying or releasing electromagnetic brake, etc.

• The Torque detection (TU) signal turns ON when the motor output torque reaches the value of torque set in Pr.864 or
higher. The TU signal turns OFF when the motor output torque drops lower than the set value.
• Pr.864 is not available under V/F control.
• To use the TU signal, set "35" (positive logic) or "135" (negative logic) in one of Pr.190 to Pr.196 (Output terminal
function selection) to assign the function to the output terminal.

NOTE
• Changing the terminal assignment using Pr.190 to Pr.196 (Output terminal function selection) may affect the other
functions. Set parameters after confirming the function of each terminal.
