This function can detect an over/undertorque in
a certain speed range as a result of machine
fatigue. It is triggered by a certain operation
time and uses the OL1 detection settings (L6-
01 to L6-03)
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).
• Sets the speed that triggers mechanical
weakening detection.
• When L6-08 is set for an unsigned value, the
absolute value is used even if the setting is
negative.
Sets the time a mechanical weakening has to be
detected before an Alarm/Fault is triggered.
Sets the operation time (U1-04) that has to be
passed before Mechanical weakening detection
is active.
