12.6 H: Terminal Function Selection
Note:
Parameter A1-02 [Control Method Selection] selects which parameter is the reference.
A1-02 Setting
0
2
ON : Output frequency < value of E1-09 or b2-01.
OFF : Output frequency ≥ value of E1-09 or b2-01.
■
2: Speed Agree 1
Setting Value Function
2 Speed Agree 1
Note:
The detection function operates in the two motor rotation directions.
ON : The output frequency is in the range of "frequency reference ± L4-02".
OFF : The output frequency does not align with the frequency reference although the drive is
running.
■
3: User-Set Speed Agree 1
Setting Value Function
3 User-Set Speed Agree 1
Note:
The detection function operates in the two motor rotation directions. The drive uses the L4-01 value as the forward/reverse detection
level.
ON : The output frequency is in the range of "L4-01 ± L4-02" and the range of frequency
reference ± L4-02.
OFF : The output frequency is not in the range of "L4-01 ± L4-02" nor the range of frequency
reference ± L4-02.
