Mech Fatigue Detect Speed
Level
Sets the speed level where the drive will operate the mechanical deterioration detection function, as a
percentage of the Maximum Output Frequency.
Note:
Parameter A1-02 [Control Method Selection] selects which parameter is the maximum output
frequency.
• A1-02 ≠ 8 [EZOLV]: E1-04 [Maximum Output Frequency]
• A1-02 = 8: E9-02 [Maximum Speed]
