1 : oL5 @ Speed > L6-09 - Alarm
When the speed (signed) ≥ L6-09 [Mech Fatigue Detect Speed Level], the drive detects mechanical weakening. The
drive will detect oL5 [Mechanical Weakening Detection 1] and continue operation.
2 : oL5 @ lSpeedl > L6-09 - Alarm
When the speed (absolute value) ≥ L6-09, the drive detects mechanical weakening. The drive will detect oL5 and
continue operation.
3 : oL5 @ Speed > L6-09 - Fault
When the speed (signed) ≥ L6-09, the drive detects mechanical weakening. The drive will detect oL5 and stop
operation.
4 : oL5 @ lSpeedl > L6-09 - Fault
When the speed (absolute value) ≥ L6-09, the drive detects mechanical weakening. The drive will detect oL5 and stop
operation.
5 : UL5 @ Speed < L6-09 - Alarm
When the speed (signed) ≤ L6-09, the drive detects mechanical weakening. The drive will detect UL5 [Mechanical
Weakening Detection 2] and continue operation.
6 : UL5 @ lSpeedl < L6-09 - Alarm
When the speed (absolute value) ≤ L6-09, the drive detects mechanical weakening. The drive will detect UL5 and
continue operation.
7 : UL5 @ Speed < L6-09 - Fault
When the speed (signed) ≤ L6-09, the drive detects mechanical weakening. The drive will detect UL5 and stop
operation.
8 : UL5 @ lSpeedl < L6-09 - Fault
When the speed (absolute value) ≤ L6-09, the drive detects mechanical weakening. The drive will detect UL5 and stop
operation.

L6-09: Mech Fatigue Detect Speed Level
No.
Name
(Hex.)
L6-09 Mech Fatigue Detect Speed
Level
(0469)
Parameters L6-01 to L6-03 [Torque Detection 1 Settings Parameters] set the overtorque/undertorque detection
conditions.
When L6-08 = 2, 4, 6, 8 [Mechanical Fatigue Detect Select = Speed : unsigned], the setting value of L6-09 is the
absolute value. When L6-09 is set to a negative number, the drive processes this value as a positive number.
■
L6-10: Mech Fatigue Detect Delay Time
No.
Name
(Hex.)
L6-10 Mech Fatigue Detect Delay
Time
(046A)
When the detection conditions set in L6-08 [Mechanical Weakening Detect Ope] continue for the time set in L6-10,
the drive will detect mechanical weakening.
■
L6-11: Mech Fatigue Hold Off Time
No.
