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

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%

(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
