Figure 7-26 Stall Overvoltage
Auto current limiting function is used to limit the load current under the
preset current in real time to avoid trip due to over-current. This function
is especially useful for the applications of larger load inertia or sharp
change of load.
PL.07 defines the threshold for current limiting. Its setting is a percentage
of inverter rated current.
The action mode of auto current limiting function is decided by PL.09.
PL.09
＝
0: When running in constant speed, auto current limit is invalid
PL.09
＝
1: When running in constant speed, auto current limit is valid
PL.09
＝
2: Auto current limit is valid all the time ( mode 1 )
PL.09
＝
3: Reserved
PL.09
＝
4: Reserved
PL.09
＝
5: Auto current limit is valid all the time ( mode 2 )
Because the output frequency might change during current limiting, the
function should be used for applications that require constant speed and
stable frequency output.
