Code Name/Description Setting range Factory settings
SdC1 [Auto DC inj. level 1] 0 to 1.2 In
1)
0.7 In
1)
Level of standstill DC injection current. This parameter can be activated if [Auto DC injection] (AdC) see "[Auto DC injection] AdC-" on page
208 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.
tdCI [Auto DC inj. time 1] 0.1 to 30 s 0.5 s
Standstill injection time.
This parameter can be activated if [Auto DC injection] (AdC) see "[Auto DC injection] AdC-" on page 208 is not set to [No] (nO) .
If [Motor control type] (Ctt) page 63 on [FVC] (FUC) or [Sync. Motor.] (SYn) is set, this time is the hold time at zero speed.

1)
2. Level of standstill DC injection current.
This parameter can be activated if [Auto DC injection] (AdC) see "[Auto DC injection] AdC-" on page 208 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] 0 to 30 s 0 s
2. Standstill injection time.
This parameter can be activated if [Auto DC injection] (AdC) , see "[Auto DC injection] AdC-" on page 208 is set to [Yes] (YES)
1) In is the same as the rated current specified in the installation instructions or on the nameplate of the inverter.

Note:
If [Motor control type] (Ctt) ( see "Drive parameters (Ctt)" on page 153 ) 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.
These parameters only appear if the corresponding function has been selected in another menu. When the parameters can also be
accessed and adjusted from within the configuration menu for the corresponding function, their description is detailed in these menus, on
the pages indicated, to aid programming.
