2: Speed Agree 1
Setting Value Function
2 Speed Agree 1
Note:
• The detection function operates in the two motor rotation directions.
• The drive outputs the motor speed status when A1-02 = 3, 7 [CLV, CLV/PM]. It also outputs the motor speed status when A1-02 = 4
and n4-72 = 1.
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.
