[LOSS LINE PHASE ] (IPL-) AND [OVERTEMP. DRIVE] (OHL-)
Code Name/Description Setting range Factory settings
IPL- [Input phase loss]
IPL [Input phase fault] According to in-
verter performance
nO [No.] (nO) : Fault ignored; to be used when the inverter is supplied via a single phase supply or by the DC bus.
YES [freewheel stop] (YES) : Fault with freewheel stop.
In the case of loss of one phase the inverter switches to the fault mode [Loss Power Phase] (IPL) ; in the event of the loss of two or three phases,
the inverter continues operating until it trips due to undervoltage.
Factory setting: [No] (nO) für 8I84T200037.01P-1 to 8I84T200300.01P-1, [freewheel stop] (YES) for all others.
OHL- [DRIVE OVERHEAT]
OHL [DRIVE OVERHEAT] [freewheel stop] (YES)
Caution!
RISK OF DAMAGE TO THE SYSTEM
The inverter is not protected when faults are inhibited. This invalidates the warranty. Check that the possible consequences do
not present any risk.
Failure to observe these instructions can result in damage to property.
Behavior in the event of the inverter overheating.
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 frequency 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) : Stopping via ramp.
FSt [Quick stop] (FSt) : Quick stop
dCI [DC brak.] (dCI) : Stop by DC injection
This normal hold cannot be used with certain other functions. see "APPLICATION FUNCT. FUn-" on page 197 .
Note:
A fault trip will occur when the thermal state reaches 118% of the rated state and reactivation will occur when the state falls back
below 90%.
tHA [Drv therm. state al] 0 to 118% 100%
Trip threshold for inverter thermal alarm (logic output or relay)
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.
Parameter that can be modified during operation or when stopped.
