[ENCODER FAULT] (Sdd-) and [LIMIT. CURRENT/TORQUE] (tld-)
Code Name/Description Setting range Factory settings
Sdd- [ENCODER FAULT]
Can be activated if the encoder option card has been inserted and the encoder is used for the speed feedback ( see "Drive parameters (EnC -
EnU)" on page 157 ).
Sdd [Load slip detection] [No] (nO)
nO
[No]
(nO) : Fault is not monitored. Only the alarm can be assigned to a logic output or a relay.
YES [Yes] (YES) : Monitored fault.
[Load slip detection] (Sdd) is forced to [Yes] (YES) if [Motor control type] (Ctt) = [FVC] (FUC) .
The error is tripped by a comparison with the ramp output and the actual speed value and is only effective for speeds of more than 10% of the
[rated motor frequency] (FrS) , see "Drive parameters (bFr - nSP)" on page 151 .
In the event of a fault the inverter switches off in a free run, and if the brake logic function has been configured, the braking command is set to 0.
ECC [Encoder coupling] [No] (nO)
nO
[No]
(nO) : Fault is not monitored.
YES [Yes] (YES) : Monitored fault.
If the brake logic control function has been configured, the factory setting switches to [Yes] (YES) . [Encoder coupling] (ECC) = [Yes] (YES)
is only possible if [load slip detection] (Sdd) = [Yes] (YES) , if [Motor control type] (Ctt) = [FVC] (FUC) and if [BRAKE LOGIC] (bLC) does
not equal [No] (nO) .
The monitored fault is a break in the mechanical coupling of the encoder.
In the event of a fault the inverter switches off in a free run, and if the brake logic function has been configured, the braking command is set to 0.
ECt [Encoder test time] 2 to 10 s 2 s
Filtering time of the encoder fault.
The parameters can be activated if [Encoder coupling] (ECC) = [Yes] (YES) .
tId- [TORQUE/CURRENT LIM .]
SSb [Trq/I limit. stop] [ign fault] (nO)
Behavior in the event of switching to torque or current limiting mode
nO [ign fault] (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) : Deceleration via ramp
FSt
[Quick stop]
(FSt) : Quick stop
dCI [DC inj.] (dCI) : Stop by DC injection. This function cannot be used with certain other functions.
StO
[Trq/I limit. time out]
0 to 9999 ms 1000 ms
(If fault has been configured).
Delay in the detection of the limit fault SSF.
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.
