Description
the weight to P92.41 and set P92.39=2, the
LED keypad displays "LoAd2". After pressing
"Run", the autotuning starts, and the obtained
torque value is automatically saved to P92.43.
In addition, the VFD decelerates to stop. When
the VFD stops, the LED keypad does not
display "LoAd2".

When the weighing function is enabled, if the
VFD reaches the constant speed running state,
the VFD output torque is obtained in real time,
and then the present weight is calculated by
using the torque and weight line simulated by
weight autotuning. The weight is displayed
through P94.37.
If the present weight is greater than the
protection point,
reported, and the VFD stops. If the present
weight is less than the protection point but
greater than the pre-alarm point, the overweight
alarm is reported, but the VFD still runs.
When the weighing function is enabled, the
VFD displays the weight in real time during
constant speed running; the VFD displays zero
during ACC/DEC or stop.
