Setting 0: During Run
Output closes when the drive is outputting a voltage.
Status
Open Drive is stopped.
Closed A Run command is input or the drive is in deceleration or DC injection.
Setting 1: Zero Speed
Terminal closes when the output frequency or motor speed (CLV, CLV/PM) falls below the minimum output frequency set
to E1-09 or b2-01.
Status
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
Note: In CLV and CLV/PM control modes, the zero speed level is defined by b2-01. In all other control modes, the zero speed level is the minimum
output frequency set to E1-09.
Output frequency
Setting 2: Speed Agree 1 (f
Closes when the actual output frequency or motor speed (CLV, CLV/PM) is within the Speed Agree Width (L4-02) of the
current frequency reference regardless of the direction.
Status
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.
