2.7 H: Terminal Functions
Setting 1: Zero speed
Terminal closes whenever the output frequency or motor speed (CLV) falls below the minimum output frequency set in
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: When using CLV 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 in E1-09.
Figure 2.51
Setting 2: Speed agree 1 (f
Closes whenever 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.
Status
Open Output frequency or motor speed does not match the frequency reference while the drive is running.
Output frequency or motor speed is within the range of frequency reference ±L4-02.
Closed
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.

Speed agree 1
Refer to L4-01, L4-02: Speed Agreement Detection Level and Detection Width on page 204
Setting 3: User-set speed agree 1 (f
Closes whenever the actual output frequency or motor speed (CLV) and the frequency reference are within the speed
agree width (L4-02) of the programmed speed agree level (L4-01).
Status
The output frequency is outside the range "L4-01 ± L4-02" or outside the range "frequency reference ±L4-02".
Open
The output frequency is within the range "L4-01 ± L4-02" and also within the range "frequency reference ±L4-02".
Closed
Note: Frequency detection works in both forward and reverse. The value of L4-01 is used as the detection level for both directions.
