[DYNAMIC LOAD DETECT.] (dLd-)
Code Name/Description Setting range Factory settings
dLd- [DYNAMIC LOAD DETECT.]
Load variation detection. The parameter is accessible if
[optim HSP hoist]
(HSO) is not equal to
[No]
(nO) .
tLd [Dynamic load time] [No] (nO)
Activation of the detection of load variations and setting the delay of the fault acquisition
[Dynamic load fault]
(dLF) .
nO [No] (nO) : No detection of a dynamic load.
- 0.00 s to 10.00 s : Sets the delay for the acquisition of the fault.
dLd
[Dynamic load threshold]
1 to 100% 100%
Adjustment of the trip threshold for load variation detection, as a % of the load measured during the frequency step.
dLb
[Dyn. load Mgt.] [freewheel stop]
(YES)
Behavior of the inverter in the event of a load variation fault.
nO [No] (nO) : Fault is ignored.
YES [freewheel stop] (YES) : Freewheel stop
Stt [in accordance with STT] (Stt) : Stop in accordance with the configuration of [STOP MODE] (Stt) , see "STOP MODE (Stt-)" on page 206 , without
fault tripping. In this case, the alarm relay does not open and once the fault disappears the inverter is ready for operation in accordance with the
restarting conditions of the active command channel (for example according to [2/3-wire ctrl] (tCC) and [Type 2-wire ctrl] (tCt) , see "Input and
output parameters (tCC - rr5)" on page 166 , if the control is on the terminal side). Configuring an alarm for this fault is recommended (assigned
to a logic output, for example) in order to indicate the cause of the stop.
LFF [FALLBACK SPEED] (LFF) : Change to fallback speed, maintained as long as the fault persists and the run command has not been removed
1)
.
rLS
[Hold freq.]
(rLS) : The inverter maintains the speed being applied when the fault occurred, as long as the fault is present and the run command
has not been removed
1)
.
rMP [StopRamp] (rMP) : Deceleration via ramp
FSt [Quick stop] (FSt) : Quick stop
1) Since the fault does not trip a stop in this case, the display of this fault must be assigned to a relay or a logic output.
