ULt
• Application underload time delay
0 to 100 s 0 s
ULt can be adjusted between 0 and 100 s.
If the motor current undershoots the underload threshold LUL for longer than the adjustable time delay
ULt, the drive will stop running and display ULF (Process underload fault) page 90
.
Underload detection is only active when the system is in steady state (speed reference reached).
A value of 0 will disable application underload detection.
LUL
• Application Underload threshold
20 to 100% of nCr 60%
Visible only if Application underload time delay ULt is not set to 0. This parameter is used to detect an
application underload condition on the motor. Application Underload thresholdLUL can be adjusted
between 20 and 100% of the nominal drive current
Ftd
• Motor frequency threshold
0 to 400 Hz 50 or 60 Hz
According to drive
rating
Visible only if R1 assignment r1 page 51 or a LO1 assignment LO1 page 52 is set to FtA.
Ctd
• Motor current threshold
0 to 1.5 In (1) InV
Visible only if R1 assignment r1 page 51 or a LO1 assignment LO1 page 52 is set to CtA.
ttd
• Motor thermal state threshold
0 to 118% of tHr 100%
Visible only if R1 assignment r1 page 51 is set to tSA.
