[FALLBACK SPEED] (LFF-), [FAST STOP] (FSt-) and [DC INJECT.] (dCI)
Code Name/Description Setting range Factory settings
LFF- [FALLBACK SPEED]
LFF [Fallback speed] 0 to 599 Hz 0 Hz
Selection of the fallback speed
FSt- [FAST STOP]
dCF [Ramp divider]
1)
0 to 10 4
The activated ramp (dEC or dE2) is then divided by this coefficient in the sending of stop commands.
Value 0 corresponds to a minimum ramp time.
dCI-
[DC Injection]
IdC [DC inject. level 1]
1)3)
0.1 to 1.41 In
2)
0.64 In
2)
Level of DC injection braking current activated via logic input or selected as stop mode.
Note:
Check that the motor will withstand this current without overheating.
Failure to follow this instruction can result in equipment damage.
tdI [DC injection time 1]
1)3)
0.1 to 30 s 0.5 s
Maximum duration of current injection [Current DC brake 1] (IdC) . After this time has expired, the DC connection becomes
[DC current brake 2] (IdC2) .
IdC2 [DC inject. level 2]
1)3)
0.1 In
2)
to
[DC current brake 1]
(IdC)
0.5 In
2)
The braking current is activated by the logic input or as a stop mode is selected, once the time span [DC injection time 1] (tdI) has expired.
Caution!
Check that the motor will withstand this current without overheating.
Failure to follow this instruction can result in equipment damage.
tdC [DC injection time 2]
1)3)
0.1 to 30 s 0.5 s
Maximum braking time
[DC current brak. 2]
(IdC2) for the DC injection, only selected as stop mode.
(Accessible if [STOP MODE] (Stt) = [DC brak.] (dCI ) ).
1) Access to this parameter is also possible via the menu [SETTINGS] (SEt-) and [APPLICATION FCT.] (FUn-) .
2) In is the same as the rated current specified in the installation instructions and on the nameplate of the inverter.
3) Warning: These settings are independent of the function [Auto DC injection] (AdC-) .
Parameter that can be modified during operation or when stopped.
