Under-torque judging:
If the torque is continually less than the torque detection value (P06.24) within the detection time (P06.25),
it is considered as the signal of under-torque detected.
Action selection for under-torque detected:
0: Under-torque detection is disabled
Do not detect under-torque.
1: Continue to run after the under-torque is detected only when the speed is consistent.
Detect the under-torque only in the process of running with the constant speed and the drive continues to
run after the under-torque is detected.
2: Continue to run after the under-torque is detected during running
The drive continues to run after the under-torque is detected during the whole running process.
3: Turn off the output after the under-torque is detected only when the speed is consistent.
Detect the under-torque only in the process of running with the constant speed and the drive will stop the
output and the motor will coast to stop after the under-torque is detected.
4: Turn off the output after the under-torque is detected during running
The drive will stop the output and the motor will coast to stop after the under-torque is detected in
the whole running process.
Under the V/F control mode, when the setting value is 100
％, it corresponds with the rated current of the
drive. Under the vector control mode, when the setting value is 100
％, it corresponds with the rated
torque of the motor. The over-torque/under-torque signal output can be monitored with the digital terminal
Yi or relay.
