Closes when the actual output frequency or motor speed (CLV, CLV/PM) and the frequency reference are within the speed
agree width (L4-02) of the programmed speed agree level (L4-01).
Status Description
Open Output frequency or motor speed and frequency reference are not both within the range of L4-01 ±L4-02.
Closed Output frequency or motor speed and the frequency reference are both within the range of L4-01 ±L4-02.
Note: Frequency detection works in forward and reverse. The value of L4-01 is used as the detection level for both directions.

H3-01: Terminal A1 Signal Level Selection
Selects the input signal level for analog input A1.
No. Name Setting Range Default
H3-01 Terminal A1 Signal Level Selection 0 to 1 0
Setting 0: 0 to 10 Vdc
The
input level is 0 to 10 Vdc. The minimum input level is limited to 0%, so that a negative input signal due to gain and bias
settings will be read as 0%.
Setting 1: -10 to 10 Vdc
The input level is -10 to 10 Vdc. If the resulting voltage is negative after being adjusted by gain and bias settings, then the
motor will rotate in reverse.
