Quick Start Over current
Suppression Gain
0~100 30
○
In process of inverter acceleration/deceleration, when output current more than overcurrent stall
protection current, frequency converter to stop deceleration process, keep the current running
frequency, after the output current drops tocontinue to acceleration/deceleration.
Overcurrent stall gain, used to adjust in the process of acceleration/deceleration, frequency converter
overcurrent control capability. The biger the value is, the greater the inhibition of overcrrent ability is.
On the premise of not occur overcurrent, the gain settings as small as possible.
For small inertia load, the gain of the overcurrent stall is small is better, otherwise the system dynamic
response is slow. For large inertia load, this value should be larger, otherwise the supppression effect
is not good, may apppear overcurrent fault.
When overcurrent stall gain is set to 0, cancel the function of overcurrent stall..

○
Can select the inverter in the power, to detect wether the motor is short circuit to ground.
If this function is effective, then inverter UVW terninal will have voltage output after power on a period
of time.

○
Selecte whether to protect the intput phase loss.
Just G type 11 kW and above power of VD120 inverter have the input phase loss protection function,
P type machine under the power of 7.5 kW, regardless of F8-13 set to 0 or 1 no input phase protection
function.

F8-19 Offload Detection Time 0.0s~60.0s 1.0s
○
If offload protection function is effective, then when the inverter output current is less than the loffoad
detection levels F8-18 and duration time is greater than the offload detection time F8-19, the inverter
output frequency decreased to 7% of the rated frequency automatically. During the offload protection,
if the load recovery, then frequency inverter automatic recovery to run according to set ferquency.
