The drive detects mechanical weakening through overtorque or undertorque as specified by the conditions set in
L6-08 to L6-11 [MechFatigue Hold Off Time], and L6-56 to L6-58 [MechF Action to MechF Method] . Set
overtorque/undertorque detection conditions in L6-01 to L6-03 [Trq Det1 Select to Trq Det1 Time] . The drive
disables the operation selection set in L6-01 [Trq Det1 Select] .
0 : Disabled
The drive does not detect mechanical weakening.
1 : Enabled
The drive detects mechanical weakening. Use parameters L6-56 [MechF Action] , L6-57 [MechF AbsSpeed] , and
L6-58 [MechF Method] to adjust the conditions.
■
L6-09: MechFatigue Speed Detect Level
No.
(Hex.)
Name Description
Default
(Range)
L6-09
(0469)
MechFatigue Speed Detect
Level
Sets the speed level where the drive will operate the mechanical deterioration detection function,
as a percentage of the Maximum Output Frequency.
110.0%
(-110.0 - 110.0%)
Parameters L6-01 to L6-03 [Trq Det1 Select to Trq Det1 Time] set the overtorque/undertorque detection
conditions.
When L6-08 = 2, 4, 6, 8 [MechF Enable = 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: MechFatigue Delay Time
No.
(Hex.)
Name Description
Default
(Range)
L6-10
(046A)
MechFatigue Delay Time
Sets the time for mechanical deterioration detection.
0.1 s
(0.0 - 10.0 s)
When the detection conditions set in L6-08 [MechF Enable] continue for the time set in L6-10 , the drive will
detect mechanical weakening.
■
L6-11: MechFatigue Hold Off Time
No.
(Hex.)
Name Description
Default
(Range)
L6-11
(046B)
MechFatigue Hold Off
Time
Sets the time that the drive will start mechanical deterioration detection triggered by the
cumulative operation time of the drive.
0 h
(0 - 65535 h)
When the total operation time of the drive is more than the value set in L6-11 , the drive will detect mechanical
weakening. Use U4-01 [Cumulative OpeTime] to monitor the drive total operation time.
■
L6-50: Trq Det1 Type
No.
(Hex.)
Name Description
Default
(Range)
L6-50
(04CC)
Trq Det1 Type
Sets the speed range that detects overtorque and undertorque.
0
(0, 1)
■
L6-51: Trq Det1 Action
No.
(Hex.)
Name Description
Default
(Range)
L6-51
(04CD)
Trq Det1 Action
Sets operation of drives (operation status) after detection.
0

L6-52: Trq Det1 Condition
No.
(Hex.)
Name Description
