Up/Down 2 Bias Lower
Limit
Sets the lower limit of the Up/Down 2 bias 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]
