All Modes
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 oL3/UL3 detection
settings (L6-01, L6-02, 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.
