Setting 1: Zero Speed
The output closes when the output frequency or motor speed falls below the minimum output frequency set to E1-09 or b2-01.
Status Description
Open Output frequency is above the minimum output frequency set to E1-09 or b2-01
Closed Output frequency is less than the minimum output frequency set to E1-09 or b2-01

Agree 1)
The output closes when the actual output frequency or motor speed is within the Speed Agree Width (L4-02) of the current
frequency reference regardless of the direction.
Status Description
Open Output frequency or motor speed does not match the frequency reference while the drive is running.
Closed Output frequency or motor speed is within the range of frequency reference ±L4-02.
Note: Detection works in forward and reverse.
