All Modes
L4-03 sets the frequency detection level for contact output functions H2-
= 13, 14, 15, 16.
L4-04 sets the hysteresis or allowable margin for speed detection.
All Modes
0: Stop. Drive stops when the frequency reference is lost.
1: Run. Drive runs at a reduced speed when the frequency reference is lost.
If the frequency reference decreases to 10% of the frequency reference of
0.4 s before, the drive runs at "frequency reference of 0.4 s before × value
set in L4-06".
Note: This parameter is valid only when Frequency Reference Selection 1
is set to analog input terminals (b1-01 = 1).
All Modes
Sets the percentage of the frequency reference that the drive should run
with when the frequency reference is lost.
All Modes
1: Detection always enabled.
L5: Fault Restart
All Modes
Sets the number of times the drive may attempt to restart after faults occur.
All Modes
0: Fault output not active.
1: Fault output active during restart attempt.
All Modes
Sets the amount of time to wait between performing fault restarts.
All Modes
0: Continuously attempt to restart while incrementing restart counter only
at a successful restarts.
1: Attempt to restart with the interval time set in L5-04 and increment the
restart counter with each attempt.
L6: Torque Detection
All Modes
0: Disabled
1: oL3 detection only active during speed agree, operation continues after
detection
2: oL3 detection always active during run, operation continues after
detection
3: oL3 detection only active during speed agree, output shuts down on an
oL3 fault
4: oL3 detection always active during run, output shuts down on an oL3
fault
5: UL3 detection only active during speed agree, operation continues after
detection
6: UL3 detection always active during run, operation continues after
detection
7: UL3 detection only active during speed agree, output shuts down on an
oL3 fault
8: UL3 detection always active during run, output shuts down on an oL3
fault
