218
0: Continuously attempt to restart while incrementing restart counter only at
a successful restart (same as F7 and G7).
1: Attempt to restart with the interval time set in L5-04 and increment the
restart counter with each attempt (same as V7).
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
Sets the overtorque and undertorque detection level.
Sets the time an overtorque or undertorque condition must exist to trigger
torque detection 1.
0: Disabled
1: oL4 detection only active during speed agree, operation continues after
detection
2: oL4 detection always active during run, operation continues after detection
3: oL4 detection only active during speed agree, output shuts down on an oL4
fault
4: oL4 detection always active during run, output shuts down on an oL4 fault
5: UL4 detection only active during speed agree, operation continues after
detection
6: UL4 detection always active during run, operation continues after detection
7: UL4 detection only active during speed agree, output shuts down on an oL4
fault
8: UL4 detection always active during run, output shuts down on an oL4 fault
Sets the overtorque and undertorque detection level.
Sets the time an overtorque or undertorque condition must exist to trigger
torque detection 2.
This function can detect an overtorque or undertorque in a certain speed range
as a result of machine fatigue. It is triggered by a specified operation time and
uses the oL1 detection settings (L6-01 and L6-03).
0: Mechanical Weakening Detection disabled.
1: Continue running (alarm only). Detected when the speed (signed) is greater
than L6-09.
2: Continue running (alarm only). Detected when the speed (not signed) is
greater than L6-09.
3: Interrupt drive output (fault). Detected when the speed (signed) is greater
than L6-09.
4: Interrupt drive output (fault). Detected when the speed (not signed) is greater
than L6-09.
5: Continue running (alarm only). Detected when the speed (signed) is less
than L6-09.
6: Continue running (alarm only). Detected when the speed (not signed) is less
than L6-09.
7: Interrupt drive output (fault). Detected when the speed (signed) is less than
L6-09.
8: Interrupt drive output (fault). Detected when the speed (not signed) is less
than L6-09.
