Detailed instruction of parameters
If the VFD current or the output current is lower than
P11.11, and its lasting time is beyond P11.12, the VFD
will output underload pre-alarm.
Setting range of P11.11: 0–P11.09
Setting range of P11.12: 0.1–3600.0s
Select the action of fault output terminals on
undervoltage and fault reset.

LED ones:
0: Action under fault undervoltage
1: No action under fault undervoltage
LED tens:
0: Action during the automatic reset
1: No action during the automatic reset

Set the speed deviation detection time.
This parameter is used to set the speed deviation
detection time.

After the VFD starts, when P01.00=0, set P13.14 to
non-zero value and begin short circuit braking.
