[Auto DC injection] (AdC-)
Code Name/Description Setting range Factory settings
AdC- [Auto DC injection]
AdC [Auto DC injection] [Yes] (YES)
Automatic current injection on stopping (at the end of the ramp)
nO [No] (nO) : No activation.
YES [YES] (YES) : Activation with adjustable duration
Ct [permanent] (Ct) : Continuous activation at standstill.
Warning!
This function blocks the function [Magnet Mot] (FLU) ( see "FLUXING BY LI (FLI-)" on page 217 ). If [Magnet Mot] (FLU) is set to
[permanent] (FCt) , [Auto DC injection] (AdC) must be set to [No] (nO) .
Note:
This parameter gives rise to the injection of current even if a run command has not been sent. It can be accessed with the frequency
inverter running.
SdC1 [Auto DC inj. level 1]
1)
0 to 1.2 In
2)
0.7 In
2)
Height of the DC connection at standstill
[Auto DC injection]
(AdC) is not set to
[No]
(nO) . For this parameter, the value 0 will be forced if
[Motor
control type] (Ctt) ( see "Drive parameters (Ctt)" on page 153 ) = [Sync. Motor.] (SYn) .
Caution!
Check that the motor will withstand this current without overheating.
Failure to follow this instruction can result in equipment damage.
tdC1 [Auto DC inj. time 1]
1)
0.1 to 30 s 0.5 s
Standstill injection time. The parameter can be activated if
[Auto DC injection]
(AdC) is not set to
[No]
(nO) .
If [Typ Motor control] (Ctt) ( see "Drive parameters (Ctt)" on page 153 ) is set to [FVC] (FUC) or [Sync. Motor] (Syn) , this time is the hold time
at zero speed.
SdC2
[Auto DC inj. level 2]
1)
0 to 1.2 In
2)
0.5 In
2)
2nd level of standstill DC injection current.
The parameter can be activated if [Auto DC injection] (AdC) is not set to [No] (nO) .
For this parameter, the value 0 will be forced if [Motor control type] (Ctt) ( see "Drive parameters (Ctt)" on page 153 ) = [Sync. Motor.] (SYn) .
Caution!
Check that the motor will withstand this current without overheating.
Failure to follow this instruction can result in equipment damage.
tdC2 [Auto DC inj. time 2]
1)
0 to 30 s 0 s
2nd standstill injection time.
The parameter can be activated if [Auto DC injection] (AdC) is not set to [Yes] (YES) .

Note:
If [Motor control type] (Ctt) is set to [FVC] (FUC) : [I DC-Auto braking 1] (SdC1) , [I DC-Auto braking 2] (SdC2) and [time aut. DC
brake2] (tdC2) cannot be activated. Only [time aut. DC brake 1] (tdC1) can be activated. This is then a hold time at zero speed.
1) This parameter can also be accessed via the [SETTINGS] (SEt-) menu.
2) In is the same as the rated current specified in the installation instructions and on the nameplate of the inverter.
Parameter that can be modified during operation or when stopped.
