Parameters described in this page can be accessed by:
(1) Because, in this case, the detected fault does not trigger a stop, it is recommended to assign a relay or logic output to
its indication.
UPL [Prevention level]
133 to 261 V According to drive rating
g
Undervoltage prevention level setting in Volts, which can be accessed if [UnderV. prevention] (StP) is not [No] (nO). The
adjustment range and factory setting are determined by the drive voltage rating and the [Mains voltage] (UrES) value.
StM [Max stop time]
0.01 to 60.00 s 1.00 s
g
T
Ramp time if [UnderV. prevention] (StP) is set to [Ramp stop] (rMP).
tbS [DC bus maintain tm]
1 to 9,999 s 9,999 s
g
T
DC bus maintain time if [UnderV. prevention] (StP) is set to [DC Maintain] (MMS).
FLt- [FAULT MANAGEMENT] (continued)
tIt- [IGBT TESTS]
Strt [IGBT test]
[No] (nO)
nO
YES
[No] (nO): No test
[Yes] (YES): The IGBTs are tested on power up and every time a run command is sent. These tests cause a slight delay (a
few ms). In the event of a detected fault, the drive will lock. The following faults can be detected:
- Drive output short-circuit (terminals U-V-W): SCF display.
- IGBT inoperable: xtF, where x indicates the number of the IGBT concerned.
- IGBT short-circuited: x2F, where x indicates the number of the IGBT concerned.
FLt- [FAULT MANAGEMENT] (continued)
LFL- [4-20mA LOSS]
LFL3 [AI3 4-20mA loss]
[Ignore] (nO)
nO
YES
Stt
LFF
rLS
rMP
FSt
dCI
[Ignore] (nO): Detected fault ignored. This is the only possible configuration if [AI3 min. value] (CrL3) page 121 is not
greater than 3 mA
[Freewheel] (YES): Freewheel stop
[Per STT] (Stt): Stop according to configuration of [Type of stop] (Stt) page 158
, without fault tripping. In this case, the
fault relay does not open and the drive is ready to restart as soon as the detected fault disappears, according to the restart
conditions of the active command channel (for example, according to [2/3 wire control] (tCC) and [2 wire type] (tCt)
page
112 if control is via the terminals). Configuring an alarm for this detected fault is recommended (assigned to a logic
output, for example) in order to indicate the cause of the stop
[Fallback spd] (LFF): Change to fallback speed, maintained as long as the detected fault persists and the run command
has not been removed (1)
[Spd maint.] (rLS): The drive maintains the speed being applied when the detected fault occurred, as long as the detected
fault is present and the run command has not been removed (1)
[Ramp stop] (rMP): Stop on ramp
[Fast stop] (FSt): Fast stop
[DC injection] (dCI): DC injection stop. This type of stop cannot be used with certain other functions. See table on page 148
Code Name / Description Adjustment range Factory setting
g
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.
T
Parameter that can be modified during operation or when stopped.
