(4A4H)
Torque Detection
Selection 2
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
Default: 0
Min: 0
Max: 8
L6-05
(4A5H)
Torque Detection
Level 2
Sets the overtorque and undertorque detection level.
Default: 150%
Min: 0%
Max: 300%
L6-06
(4A6H)
Torque Detection
Time 2
Sets the time an overtorque or undertorque condition must exist to trigger
torque detection 2.
Default: 0.1 s
Min: 0.0 s
Max: 10.0 s
L6-08
(468H)
Mechanical
Weakening
Detection Operation
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.
Default: 0
Min: 0
Max: 8
L6-09
(469H)
Mechanical
Weakening
Detection Speed
Level
Sets the speed that triggers Mechanical Weakening Detection. When L6-08
is set for an unsigned value, the absolute value is used if the setting is
negative.
Default: 110.0%
Min: -110.0%
Max: 110.0%
L6-10
(46AH)
Mechanical
Weakening
Detection Time
Sets the time mechanical weakening has to be detected before an alarm or
fault is triggered.
Default: 0.1 s
Min: 0.0 s
Max: 10.0 s
L6-11
(46BH)
Mechanical
Weakening
Detection Start Time
Sets the operation time (U1-04) required before Mechanical Weakening
Detection is active.
Default: 0 h
Min: 0 h
Max: 65535 h
No.
