Mechanical
Weakening Detection
Operation
0: Mechanical Weakening Detection disabled.
1: Continue running if the speed (signed) is
greater than L6-09 (alarm only).
2: Continue running if the speed (not signed) is
greater than L6-09 (alarm only).
3: Interrupt drive output when the motor speed
(signed) is greater than L6-09 (protection
operation).
4: Interrupt drive output when the motor speed
(not signed) is greater than L6-09 (protection
operation).
5: Continue running if the speed (signed) is
less than L6-09 (alarm only).
6: Continue running if the speed (not signed) is
less than L6-09 (alarm only).
7: Interrupt drive output when the motor speed
(signed) is less than L6-09 (protection
operation).
8: Interrupt drive output when the motor speed
(not signed) is less than L6-09 (protection
operation).

Mechanical
Weakening Detection
Speed Level
• Sets the speed that triggers mechanical
weakening detection.
• Uses torque detection 1 to set the torque (L6-
01 to L6-03).
• When L6-08 is set for an unsigned value, the
absolute value is used even if the speed is a
negative value.

Mechanical
Weakening Detection
Start Time
Mechanical weakening detection is triggered
when the cumulative operation time (U4-01)
exceeds this value. When one of the multi-
function outputs is set for mechanical
weakening detection (H2-= 22) the output
signal is switched on.
