It is triggeredby a specified operation time and uses the oL3/UL3 detectionsettings (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 (notsigned) 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 (notsigned) 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 (notsigned) is less than L6-09.7: Interrupt drive output (fault).
