5: Alm Spd 6: Alm [Spd] 7: Flt Spd 8: Flt [Spd] 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 oL1 detection settings (L6-01 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. Default: 0 Range: 0 to 8 – L6-09 (0469) Mechanical Weakening Detection Speed Level MechFat Det Spd Sets the speed that triggers Mechanical Weakening Detection. When L6-08 is set for an unsigned value, the absolute value is used if the setting is negative. Default: 110.0% Min.: -110.0 Max.: 110.0 – L6-10 (046A) Mechanical Weakening Detection Time MechFat Det Time Sets the time mechanical weakening has to be detected before an alarm or fault is triggered. Default: 0.1 s Min.: 0.0 Max.: 10.0 – L6-11 (046B) Mechanical Weakening Detection Start Time MechFat Det Hour Sets the operation time (U1-04) required before Mechanical Weakening Detection is active.
