[NETWORK FAULT MGT.] (CLL-)
Code Name/Description Factory settings
CLL- [COMM FAULT MGT]
CLL [Network fault mgt] [freewheel stop] (YES)
Behavior of the inverter in the event of a communication fault with a communication card
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)
.
Note:
The ACOPOSinverter P84 is reconfigured when the CPU is restarted. By configuring CLL = rLS, the CPU is not able to configure
the inverter → this leads to an error (module OK = FALSE).
Troubleshooting:
Download parameter = 0 → With this configuration, the inverter will be configured when the CPU is restarted.
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 .
COL [Mgt. faultCANopen] [freewheel stop] (YES)
Behavior of the inverter in the event of a communication fault with an integrated bus connection.
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

SLL [Modbus fault mgt] [freewheel stop] (YES)
Not applicable
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.
