Setting 1: Zero Speed
Terminal closes when the output frequency or motor speed (CLV) falls below the minimum output frequency set in
E1-09 or b2-01.
Note: When using CLV control mode, the zero speed level is defined by b2-01. In all other control modes, the zero speed level is the
minimum output frequency set in E1-09.

out
Agree 1)
Closes when the actual output frequency or motor speed (CLV) is within the Speed Agree Width (L4-02) of the current
frequency reference regardless of the direction.
Note: 1. Detection works in both directions, forward and reverse.
2. When using the CLV control mode, it is the motor speed
±
L4-02 that is considered.

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.
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.
