Goodrive3000 series medium voltage VFD
Function
code
The function code is used to enable protection against phase loss.
Function
code
Frequency drop at
P11.01
transient power-off
The function code is used to enable the frequency decrease at sudden power loss.
Function
code
Frequency drop rate
P11.02
at transient power-off
If the bus voltage drops to the sudden frequency decreasing point due to the power loss of the grid, the VFD begins to
decrease the running frequency according to P11.02 to make the motor in power generation state. The feedback power
can maintain the bus voltage to ensure the continuous running of the VFD until the recovery of power.
Voltage class
Frequency decrease point at sudden
power loss (bus voltage)
Note:
1. Adjusting the parameter properly can prevent the stop caused by the VFD protection during shifting the grid.
2. This function can be enabled only when the input phase protection function is disabled.
