5.8.9 Output torque detection
Magnetic flux Magnetic flux Magnetic flux PM PM PM
A signal is output when the motor torque is higher than the setting.
This function can be used for electromagnetic brake operation, open signal, etc.
Pr. Name
864 Torque detection
M470
• The Torque detection (TU) signal turns ON when the output torque reaches the detection torque value set in Pr.864 or
higher. The TU signal turns OFF when the output torque drops lower than the detection torque value.
• Pr.864 is not available under V/F control.
• For 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.

TU ON
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.
