In the VF control mode, the motor output current is used as the load warning judgment value, 100.0% corresponds to
the rated motor current; in the vector control mode, the motor output torque is used as the load warning judgment value,
100.0% corresponds to the rated output torque of the motor, and the load warning judgment value is The detection time
[F10.19/F10.21] is compared with the detection threshold [F10.18/F10.20], and the corresponding action is performed
according to [F10.17]. The alarm can be output through the terminal output. See Y Terminal function for details..
Check out the selection (Protection 1):
1: Detection load is too large
The running detection value is greater than [F10.18] load warning detection level 1 and the valid signal is output after
[F10.19] load warning detection time 1;
2: Excessive load detection only at constant speed
In the constant speed state, the detected value is greater than [F10.18] load warning detection level 1 and the valid
signal is output after [F10.19] load warning detection time 1;
3: Insufficient detection load
The running detection value is less than [F10.20] load warning detection level 2 and the valid signal is output after
[F10.21] load warning detection time 2;
4: Insufficient load detection only at constant speed

detection threshold when speed slip is too large
Set range: 0.0-60.0%
Factory default: 10.0%

detection time when speed slip is too large
Set range:0.0-60.0s
Factory default: 2.0s
Under VC control,if the speed feedback value and speed setting bias are more than detection threshold
[F10.24]
during the detection time
[F10.25],
inverter judges that the detection bias is too large and operate according to
[F10.23].
Speed bias detection threshold 100% corresponds to max frequency..
